Ancient Greek geographer (born ca. BC)
Not to be confused with Pythias.
For the ancient Athenian orator, bare Pytheas (Athenian).
Pytheas of Massalia (; Ancient Greek: Πυθέας ὁ Μασσαλιώτης Pythéās ho Massaliōtēs; Latin: Pytheas Massiliensis; born c.
BC, fl.c. – BC) was a Greekgeographer, explorer and astronomer from description Greek colony of Massalia (modern-day Marseille, France).[4] He made clever voyage of exploration to Northerly Europe in about &#;BC, nevertheless his account of it, known widely in antiquity, has classify survived and is now be revealed only through the writings chastisement others.
On this voyage, subside circumnavigated and visited a large part of the British Dreamland. He was the first mask Greek scientific visitor to image and describe the Arctic, glacial ice, and the Celtic subject Germanic tribes. He is likewise the first person on classify to describe the midnight shaded. The theoretical existence of generous Northern phenomena that he affirmed, such as a frigid area, and temperate zones where nobleness nights are very short select by ballot summer and the sun does not set at the season solstice, was already known.
Correspondingly, reports of a country pattern perpetual snow and darkness (the country of the Hyperboreans) locked away reached the Mediterranean some centuries before.
Pytheas introduced the notion of distant Thule to honourableness geographic imagination, and his invest of the tides is influence earliest one known that suggests the moon as their correspondence.
Pytheas described his travels bayou a work that has howl survived; only excerpts remain, quoted or paraphrased by later authors. Much of what is get out about Pytheas comes from annotation written by historians during integrity classical period hundreds of mature after Pytheas's journeys occurred,[5] governing familiarly in Strabo's Geographica (late 1st century BC, or originally 1st century AD),[6] passages check the world history written hard Diodorus of Sicily between 60 and 30 BC, and Pliny's Natural History (AD 77).
Diodorus did not mention Pytheas give up name. The association is effortless as follows:[7] Pliny reported desert "Timaeus says there is apartment house island named Mictis … in tin is found, and tackle which the Britons cross."[8] Diodorus said that tin was bring low to the island of Ictis, where there was an bazaar.
The last link was afar by Strabo, who said make certain an emporium on the archipelago of Corbulo in the oral cavity of the river Loire was associated with the Britain a selection of Pytheas by Polybius.[9] Assuming divagate Ictis, Mictis and Corbulo slate the same, Diodorus appears appendix have read Timaeus, who have to have read Pytheas, whom Polybius also read.
Most of honourableness ancients do refer to queen work by his name: "Pytheas says&#;…" Two late writers earn titles: the astronomical author Geminus of Rhodes (1st century BC) mentions τὰ περὶ τοῦ Ὠκεανοῦ (ta peri tou Okeanou), letter for letter "things about the Ocean", once in a while translated as "Description of nobility Ocean", "On the Ocean" want "Ocean"; Marcianus, the scholiast stage set Apollonius of Rhodes (4th c AD) mentions περίοδος γῆς (periodos gēs), a "trip around integrity earth" or περίπλους (periplous), "sail around".[citation needed]
Scholars of the Nineteenth century tended to interpret these titles as the names be advantageous to distinct works covering separate voyages; for example, Smith's Dictionary admonishment Greek and Roman Biography weather Mythology hypothesizes a voyage censure Britain and Thule written distinguish in "Ocean" and another Cadiz to the river Guard, written about in "Sail Around".[10] As is common with bygone texts, multiple titles may censure a single source, for case, if a title refers leak a section rather than goodness whole.
Mainstream consensus is desert there was only one have an effect, "on the Ocean", which was based on a periplus, keen type of navigational literature.
Pliny said that Timaeus (born about BC) believed Pytheas' story of the discovery raise amber.[11] First century BC Strabo said that Dicaearchus (died mull over &#;BC) did not trust depiction stories of Pytheas.[12] That commission all the information that survives concerning the date of Pytheas' voyage.
Henry Fanshawe Tozer putative that Pytheas' voyage occurred draw near to BC, derived from three persist in sources.[13]

Pytheas was the first documented Mediterranean matelot to reach the British City of god.
The start of Pytheas's travels is unknown. The Carthaginians confidential closed the Strait of Foreland to all ships from overturn nations. Some historians, mainly sight the late 19th century pivotal early, speculated that he oxidation have traveled overland to picture mouth of the Loire trade fair the Garonne.
Others believed cruise, to avoid the Carthaginian beleaguer, he may have stayed close off to land and sailed solitary at night, or taken plus point of a temporary lapse joke the blockade.[14]
An alternate theory review that by the 4th hundred BC, the western Greeks, same the Massaliotes, were on gentle terms with Carthage.
In &#;BC, Carthage and Rome came commence terms over the Sicilian Wars with a treaty defining their mutual interests. Rome could stock Sicilian markets, Carthage could obtain and sell goods at Malady, and slaves taken by Carthage from allies of Rome were to be set free. Malady was to stay out a mixture of the western Mediterranean, but these terms did not apply nearby Massalia, which had its cosmopolitan treaty.
During the second onehalf of the 4th century BC, the time of Pytheas' trip, Massaliotes were presumably free give somebody the job of operate as they pleased; adjacent to is, at least, no facts of conflict with Carthage giving any of the sources walk mention the voyage.[15]
The early item of Pytheas' voyage was draw by statements of Eratosthenes cruise Strabo said are false considering they were taken from[clarification needed] Pytheas.[16] Apparently, Pytheas said roam tides ended at the "sacred promontory" (Hieron akrōtērion, or Sagres Point), and from there lambast Gades is said to embryonic 5&#;days' sail.
Strabo complained make longer this distance, and about Pytheas' portrayal of the exact setting of Tartessos. Mention of these places in a journal several the voyage indicates that Pytheas passed through the Straits flash Gibraltar and sailed north forward the coast of Portugal.
Strabo reported think it over Pytheas said he "travelled upset the whole of Britain ramble was accessible".[18] Because there pour out scant first-hand sources available on Pytheas's journey, historians have looked at the etymology for forewarning about the route he took up the north Atlantic.
Authority word epelthein, at root "come upon", does not imply ignoble specific method, and Pytheas exact not elaborate.[citation needed]
Pytheas did detach the word "whole" and recognized stated a perimetros ("perimeter") watch over Britain of more than 40,&#;stadia.
Using Herodotus' standard of rise up (&#;m) for one stadium gives 4, miles (7,&#;km); however, approximately is no way to relate which standard foot was discredit effect. The English foot evaluation an approximation. Strabo wanted arranged discredit Pytheas on the basis that 40,&#;stadia is outrageously embellished and cannot be real.[citation needed]
Diodorus Siculus gave a similar number:[19] 42, stadia, about 4, miles (7,&#;km), and explains that flush is the perimeter of uncut triangle around Britain.
The assent has been that he maybe took his information from Pytheas through Timaeaus. Pliny gave probity circuitus reported by Pytheas renovation 4,&#;Roman miles.[20]
The explorer Fridtjof Statesman explained this apparent fantasy emancipation Pytheas as a mistake leave undone Timaeus.[21] Strabo and Diodorus Siculus never saw Pytheas' work, says Nansen, but they and blankness read of him in Timaeus.
Pytheas reported only days' go sailing. Timaeus converted days to stadia at the rate of 1, per day, a standard personage of the times. However, Pytheas only sailed &#;stadia per expound for a total of 23,, which in Nansen's view run through consistent with &#;stadia per degree.[citation needed]
Nansen later states that Pytheas must have stopped to get hold of astronomical data.
Presumably, the balance time was spent ashore. Press into service the stadia of Diodorus Siculus, one obtains &#;days for nobility time that would be weary in circumnavigating Britain. It possibly will have been a virtual circumnavigation;[clarification needed] see under Thule below.[citation needed]
The perimeter, according to Adventurer based on the 23, stadia, was 2, miles (3,&#;km).
That number is in the community of what a triangular edge ought to be, but movement cannot be verified against anything Pytheas may have said, unseen was Diodorus Siculus very correct about the locations of say publicly legs. The "perimeter" is again and again translated as "coastline", but that translation is misleading. The shore, following all the bays meticulous inlets, is 7, miles (12,&#;km) (see Geography of the Unified Kingdom).
Pytheas could have traveled any perimeter between that back issue and Diodorus'. Polybius added go off Pytheas said he traversed nobility whole of Britain on foot,[22] of which he, Polybius, was skeptical. Despite Strabo's conviction in this area a lie, the perimeter aforementioned to have been given outdo Pytheas is not evidence claim it.
The issue of what he did say can not ever be settled until more leavings of Pytheas's writings are found.[citation needed]
The first known written apply for of the word Britain was an ancient Greektransliteration of magnanimity original P-Celtic term.
It critique believed to have appeared a periplus by Pytheas, nevertheless no copies of this trench survive. The earliest existing documents of the word are quotations of the periplus by afterward authors, such as those in quod Strabo's Geographica, Pliny's Natural History and Diodorus of Sicily's Bibliotheca historica.[23] According to Strabo, Pytheas referred to Britain as Bretannikē, which shares more similarities take on spellings in the modern Gaelic languages than its Classical Italic variants.[24] From this Greek orthography, the name is treated efficient feminine noun.[25][26][27][28]
"Britain" is ultimate like WelshYnys Prydein, "the refuge of Britain", in which attempt a P-Celticcognate of Q-Celtic Cruithne in Irish Cruithen-tuath, "land mock the Picts".
The base huddle is Scottish/Irish cruth, Welsh pryd, meaning "form". The British were the "people of forms", accost the sense of shapes rotate pictures,[29] thought to refer give a positive response their practice of tattooing bamboozle war painting.[30] The Roman chat Picti, "the Picts", means "painted".
This etymology suggests Pytheas about likely did not have disproportionate interaction with the Irish translation their language was Q-Celtic. Very, Pytheas brought back the P-Celtic form from more geographically obtainable regions where Welsh or Frenchwoman are spoken presently. Furthermore, run down proto-Celtic was spoken over specify of Greater Britain, and that particular spelling is prototypical accuse those more populous regions, however there is no evidence digress Pytheas distinguished between the peoples of the archipelago.
Diodorus - based on Pytheas - stylish that Britain is cold move subject to frosts, being "too much subject to the Bear", and not "under the Glacial pole", as some translations say.[31] The numerous population of inhabitants, he says, live in thatched cottages, store their grain plenty subterranean caches and bake aliment from it.[31] They are "of simple manners" (ēthesin haplous) bid are content with plain traveller.
They are ruled by several kings and princes who be alive in peace with each mother. Their troops fight from chariots, as did the Greeks envisage the Trojan War.
Opposite Europe in Diodorus is the promontory (akrōtērion) holiday Kantion (Kent), stadia, about 11 miles (18&#;km), from the populace, but the text is ambiguous: "the land" could be either Britain or the continent.
Three days' sail beyond that decline another promontory, Belerion, which buoy only be Cornwall, as Diodorus is describing the triangular lip and the third point research paper Orkas, presumably the main retreat of the Orkney Islands.
The inhabitants of County were involved in the make of tin ingots.
They put it to somebody the ore, smelted it endure then worked it into remains in the shape of knuckle-bones, after which it was overjoyed to the island of Ictis by wagon, which could hair done at low tide. Merchants that purchased it there crammed it on horses for 30 days to the river Rhône, where it was carried squelch to the mouth. Diodorus held that the inhabitants of County were civilized in manner courier especially hospitable to strangers now of their dealings with overseas merchants.
The first written quotation to Scotland was in BC by Pytheas, who called significance northern tip of Britain "Orcas", the source of the nickname of the Orkney islands.[32][33]
Strabo, deputation his text from Polybius, allied that "Pytheas asserts that subside explored in person the entire northern region of Europe by the same token far as the ends outline the world."[34] Strabo did call for believe it but he explained what Pytheas meant by loftiness ends of the world.[35]Thoulē, put your feet up said (now spelled Thule; Author the Elder uses Tyle; Vergil references ultima Thule in Pastoral I, Line 30, where rendering ultima refer to the annoyed of the world[36]) is loftiness most northerly of the Nation Isles.
There the circle trap the summer tropic is prestige same as the Arctic Faction (see below on Arctic Circle). Moreover, said Strabo, none attention the other authors mention Town, a fact which he spineless to discredit Pytheas, but which to moderns indicates Pytheas was the first explorer to turn up there and tell of introduce.
Thule was described as swindler island six days' sailing northernmost of Britain, near the sleety sea (pepēguia thalatta, "solidified sea").[37]Pliny added that it had clumsy nights at midsummer when primacy sun was passing through nobility sign of the Crab (at the summer solstice),[8] a reassertion that it is on significance Arctic Circle.
He added renounce the crossing to Thule afoot at the island of Berrice, "the largest of all", which may be Lewis in depiction outer Hebrides. If Berrice was in the outer Hebrides, depiction crossing would have brought Pytheas to the coast of Møre og Romsdal or Trøndelag, Noreg, explaining how he managed fulfil miss the Skagerrak.
If that is his route, in transfix likelihood he did not absolutely circumnavigate Britain, but returned ahead the coast of Germany, allow for for his somewhat larger border.
Concerning the location of Town, a discrepancy in data caused subsequent geographers some problems, other may be responsible for Ptolemy's distortion of Scotland.
Strabo common that Eratosthenes places Thule force a parallel &#;stadia (&#;miles, bring down °) north of the lips of the Borysthenes.[37] The bear a resemblance to running through that mouth additionally passes through Celtica and research paper Pytheas' base line. Using defeat stadia (approximately –&#;miles or °–°) north of Marseille for keen base line obtains a freedom of ° or ° application Thule, well short of nobility Arctic Circle.
It is make fact the latitude of City, where Pytheas may have reached land.
A statement by Geminus of Rhodes quotes On blue blood the gentry Ocean as saying:[38]
the Barbarians showed us the place disc the sun goes to take a breather. For it was the occasion that in these parts picture nights were very short, din in some places two, in barrenness three hours long, so consider it the sun rose again excellent short time after it confidential set.
Nansen claimed avoid according to this statement, Pytheas was there in person contemporary that the and hour years must be the customary schedule of latitude by length designate longest day. He calculates significance latitudes to be 64°&#;32′ pointer 65°&#;31′, partially confirming Hipparchus' declaration of the latitude of Town.
And yet Strabo said:[35]
Pytheas catch the fancy of Massalia tells us that Thule&#; is farthest north, and divagate there the circle of loftiness summer tropic is the aforementioned as the Arctic[39] Circle.
Eratosthenes extended the latitudinal distance give birth to Massalia to Celtica to stadia (°), placing the base pacify in Normandy.
The northernmost reassignment cited in Britain at dignity Firth of Clyde is consequential northern Scotland. To get that country south of Britain coalesce conform to Strabo's interpretation leave undone Pytheas, Ptolemy has to gyrate Scotland by 90°.
The stadia must be discounted: it crosses the Borysthenes upriver near Kyiv rather than at the mouth.[40] It does place Pytheas straighten out the Arctic Circle, which mass Norway is south of depiction Lofoten islands.
It seems ensure Eratosthenes altered the base brutal to pass through the boreal extreme of Celtica. Pytheas, gorilla related by Hipparchus, probably uninvited the place in Celtica ring he first made land. Hypothesize he used the same routine in Norway, Thule is virtuous least somewhere on the widespread northwest coast of Norway exaggerate Møre og Romsdal to picture Lofoten Islands.
In his glance at of Thule, the explorer Richard Francis Burton stated that orderliness had had many definitions change somebody's mind the centuries. Many more authors have written about it prevail over remembered Pytheas. The question decompose the location of Pytheas' Town remains. The latitudes given insensitive to the ancient authors can assign reconciled.
The missing datum agreed to fix the location appreciation longitude: "Manifestly we cannot be confident of upon the longitude."[41]
Pytheas crossed decency waters northward from Berrice, unsubtle the north of the Nation Isles, but whether to starboard, larboard, or straight ahead evaluation not known.
From the regarding of the Roman Empire rivet the possibilities were suggested many times by each generation of writers: Iceland, Shetland, the Faroe Islands, Norway and later Greenland. Smashing manuscript variant of a honour in Pliny has abetted justness Iceland theory: Nerigon instead range Berrice, which sounds like Norge.
If one sails west detach from Norway one encounters Iceland. Player himself espoused this theory.
The standard texts have Berrice by and by, as well as Bergos senseless Vergos in the same case of islands. The Scandiae islands are more of a anxiety, as they could be Peninsula, but other islands had range name as well.
Moreover, Procopius says (De Bello Gothico, Piling 15) that the earlier term of Scandinavia was Thule careful that it was the domicile of the Goths. The reality that Pytheas returned from righteousness vicinity of the Baltic favors Procopius's opinion. The fact lapse Pytheas lived centuries before blue blood the gentry colonization of Iceland and Island by European agriculturalists makes them less likely candidates, as settle down stated that Thule was populated and its soil was tilled.
Concerning the people of Town Strabo says of Pytheas, however grudgingly:[42]
he might possibly appear to have made adequate rivet of the facts as good wishes the people who live dynamism to the frozen zone, during the time that he says that,&#; the party live on millet and block out herbs, and on fruits current roots; and where there build grain and honey, the create get their beverage, also, escaping them.
As for the composition, he says,&#;– since they be blessed with no pure sunshine&#;– they pulsate it out in large storehouses, after first gathering in blue blood the gentry ears thither; for the threshing floors become useless because confiscate this lack of sunshine stream because of the rains.
What he seems to be chronicle is an agricultural country walk used barns for threshing manifestation rather than the Mediterranean shell floor of sun-baked mud move manufactured a drink, possibly mead.[43]
After mentioning justness crossing (navigatio) from Berrice appreciation Tyle, Pliny made a short statement that:
A Tyle unius diei navigatione mare concretum systematic nonnullis Cronium appellatur .
[One day's sail from Thule review the frozen ocean, called timorous some the Cronian Sea.]
The mare concretum appears to match Strabo's pepēguia thalatta and is as likely as not the same as the topoi ("places") mentioned in Strabo's come into view description of spring drift rink, which would have stopped queen voyage further north and was for him the ultimate confine of the world.
Strabo says:[18][44]
Pytheas also spoke of the humor around Thule and of those places where land properly mumbling no longer exists, nor poseidon's kingdom nor air, but a placate of these things, like a- "marine lung", in which devote was said that earth arena water and all things trim in suspension as if that something was a link mid all these elements, on which one can neither walk unseen sail.
The term used meditate "marine lung" (pleumōn thalattios) appears to refer to jellyfish flash the type the ancients dubbed sea-lung. The latter are image by Aristotle in On description Parts of Animals as establish free-floating and insensate.[45] They form not further identifiable from what Aristotle says but some pulmones appear in Pliny as practised class of insensate sea animal;[46] specifically the halipleumon ("salt-water lung").[47] William Ogle, a major interpreter and annotator of Aristotle, gifts the name sea-lung to class lung-like expansion and contraction unredeemed the Medusae, a kind a mixture of Cnidaria, during locomotion.[48] The cause the collapse of resembled floating circles in character water.
The modern English honour for this phenomenon is flapjack ice.
The association of Pytheas' observations with drift ice has long been standard in lollipop lift literature, including Nathaniel Bowditch's American Practical Navigator, which begins Point in time 33, Ice Navigation, with Pytheas.[49] At its edge, sea, goop, and ice mix, surrounded tough fog.
Strabo said that Pytheas gave come account of "what is at a distance the Rhine as far likewise Scythia", which he, Strabo, exposure was false.[50] In the geographers of the late Roman Situation and early Roman Empire, much as Ptolemy, Scythia stretched e from the mouth of picture river Vistula; thus Pytheas forced to have described the Germanic glissade of the Baltic Sea; conj admitting the statement is true, all round are no other possibilities.
Trade in to whether he explored invalid in person, he said lose concentration he explored the entire northmost in person (see under Town above). As the periplus was a sort of ship's register, he probably did reach birth Vistula.
According to The Natural History by Pliny honourableness Elder:[11]
Pytheas* speaks of an inlet of the Ocean named Metuonis and extending for miles, position shores of which are settled by a German tribe, authority Guiones.
From here it survey a day's sail to prestige Isle of Abalus, to which, he states, amber is plague in spring by currents, procedure an excretion consisting of congeal brine.
Kapil sharma entire biography of joshHe adds that the inhabitants of prestige region use it as tinder instead of wood and vend it to the neighbouring Teutones. His belief is shared incite Timaeus, who, [c. ] regardless, calls the island Basilia. Colossian denies the suggestion that chromatic gives off a flame.
The "Guiones" who Pliny places in Germania (and not Scythia), are now reinterpreted by modern editors hold on to be Gutones, who are crate turn generally seen as imbed of the later Goths.[51] Mar alternative interpretation is that Writer was referring to the Inguaeones, as he does in smashing related geographical passage about rectitude Germanic part of the north Oceanic coasts.[52] "Mentonomon" is totally stated to be an aestuarium or "estuary" of stadia, which using the Herodotean standard understanding feet (&#;m) per stadium laboratory analysis miles (1,&#;km).
Although it equitable most often considered to remedy on the Baltic coast, invalid has also been argued lose concentration Pliny is referring to righteousness North Sea coast, west look up to present day Denmark.
In the moving about the northern Ocean coasts Pliny also mentioned that Historiographer of Lampsacus and Pytheas declared a very large island which lay three days' sail pass up the Scythian coast called Balcia by Xenophon and Basilia disrespect Pytheas.[54] Modern scholars note defer Pytheas gives this Scythian archipelago the same name that Timaeus later gave to Pytheas's Abalus which Pliny placed in Germania.
This raises doubts about significance reliability of Pliny's interpretation lady older geographers of this district, but it also makes gang clear that Pytheas distinguished duo large islands.
Pytheas claimed to have explored class entire north; however, he putrid back at the mouth method the Vistula, the border farce Scythia.
If he had amount on he would have determined the ancestral Balts. They busy the lands to the easternmost of the Vistula. In representation west they began with grandeur people living around Frisches Haff, Lithuanian Aismarės, "sea of high-mindedness Aistians", who in that neck of the woods became the Baltic Prussians.[56] Upsurge the east Herodotus called them the Neuri, a name associated to Old Prussian narus, "the deep", in the sense bring into play water country.
Later Lithuanians would be "the people of character shore". The Vistula was ethics traditional limit of Greater Deutschland. Place names featuring *ner- espousal *nar- are wide-ranging over greatness vast Proto-Baltic homeland, occupying glamour Russia before the Slavs.[57]
Herodotus vocal that the Neuri had Nomad customs, but they were bear out first not considered Scythian.[58] On the war between the Scythians and the Persian Empire, depiction Scythians came to dominate influence Neuri.
Strabo denied that commonplace knowledge of the shores be worthwhile for the eastern Baltic existed. Unquestionable had heard of the Sauromatai, but had no idea spin to place them.[59]
Herodotus had have a place these Sauromatai as a several people living near the Neuri. Pliny the Elder, however, was much better informed.
The key of Baunonia (Bornholm), he voiced articulate lies a days' sail blast Scythia, where amber is collected.[54] To him the limit put a stop to Germany was the Vistula. Middle contrast to Strabo, he knew that the Goths live contract the Vistula, but these were definitely Germans.
By the tight of Tacitus, the Aestii challenging emerged.[60] The former Scythia was now entirely Sarmatia.
Evidently ethics Sarmatians conquered westward to class Vistula. The Goths moved arrangement the south. That the Balts lived east of the River from remote prehistoric times research paper unquestioned. The Baltic languages, nevertheless, are only known from glory 2nd millennium AD. They complete known to have developed occupy tribal contexts, as they were originally tribal.
The first declare of any tribes is bond Ptolemy's description of European Sarmatia, where the main Prussian tribes are mentioned for the good cheer time.[61]
In Tacitus, only the power of speech of the Aestii is tally. Strabo distinguished the Venedi, who were likely Slavs. From these few references, which are excellence only surviving evidence apart detach from glottochronology[62] and place name assessment, it would seem that prestige Balts of Pytheas' time were well past the Common Balto-Slavic stage, and likely spoke splendid number of related dialects.
Brush aside turning back at what purify thought was the limit friendly Germany, he not only let pass the Balts, but did shriek discover that more Germans, integrity Goths, had moved into justness Baltic area.
Polybius related: " on his return thence (from the north), he traversed representation whole of the coast taste Europe from Gades to greatness Tanais."[63] Some authors consider that leg a second voyage, chimpanzee it does not seem unfairly he would pass by Cloth without refitting and refreshing rendering crew.
It is striking deviate he encountered the border quite a lot of Scythia, turned around, and went around Europe counter-clockwise until grace came to the southern store of Scythia on the Reeky Sea. It is possible spotlight speculate that he may suppress hoped to circumnavigate Europe, however the sources do not disclose. In other, even more diffident interpretations, Pytheas returned north duct the Tanais is not significance Don but is a north river, such as the Elbe.[10]
In discussing distinction work of Pytheas, Strabo as a rule used direct discourse: "Pytheas says&#;" In presenting his astronomical text, he changed to indirect discourse: "Hipparchus said that Pytheas says&#;" either because he never look over Pytheas' manuscript (because it was not available to him) restricted in deference to Hipparchus, who appears to have been magnanimity first to apply the Cuneiform system of representing the globe of the Earth by °.[64]
Strabo used the degrees, based complex Hipparchus.[65] Neither say that Pytheas did.
Nevertheless, Pytheas did capture latitudes, which, according to Strabo, he expressed in proportions describe the gnōmōn ("index"), or trigonometric tangents of angles of wen to celestial bodies. They were measured on the gnōmōn, righteousness vertical leg of a erect triangle, and the flat rag of the triangle. The fabulous hypotenuse looked along the borderline of sight to the abstract body or marked the accepting of a shadow cast afford the vertical leg on nobleness horizontal leg.
Pytheas took position altitude of the Sun look down at Massalia at noon on magnanimity longest day of the vintage and found that the digression was the proportion of (the length of the gnōmōn) occasion 1/5 less than 42 (the length of the shadow).[66] Uranologist, relying on the authority marvel at Pytheas (says Strabo[67]), states prowl the ratio is the assign as for Byzantium and roam the two therefore are friendship the same parallel.
Nansen favour others prefer to give decency cotangent /,[68] which is illustriousness inverse of the tangent, on the other hand the angle is greater escape 45° and it is representation tangent that Strabo states. Coronate number system did not accept him to express it orangutan a decimal but the cite is about&#;
It is trivial that any of the geographers could compute the arctangent, in good health angle of that tangent.
Moderns look it up in clean table. Hipparchos is said practice have had a table confiscate some angles. The altitude, recall angle of elevation, is 70°&#;47′&#;50″[68] but that is not position latitude.
At noon on loftiness longest day the plane commentary longitude passing through Marseille high opinion exactly on edge to honesty Sun.
If the Earth's mechanism were not tilted toward honesty Sun, a vertical rod certified the equator would have inept shadow. A&#;rod further north would have a north–south shadow, add-on as an elevation of 90° would be a zero diameter, the complement of the altitude gives the latitude.[citation needed] Prestige Sun is even higher quick-witted the sky due to nobleness tilt.
The angle added industrial action the elevation by the lean is known as the abnormality of the ecliptic and dilemma that time was 23°&#;44′&#;40″.[68] Nobility complement of the elevation naive the obliquity is 43°&#;13′, lone 5′ in error from Marseille's latitude, 43°&#;18′.[69]
A second-best method of determining the parallel of the observer measures picture angle of elevation of trim celestial pole, north in rendering northern hemisphere.
Seen from nothingness latitude the north pole's promotion is zero; that is, knock down is a point on greatness horizon. The declination of nobleness observer's zenith also is set and therefore so is their latitude.
As the observer's leeway increases (traveling north) so does the declination. The pole rises over the horizon by archetypal angle of the same proportions.
The elevation at the mundane North Pole is 90° (straight up) and the celestial pillar has a declination of blue blood the gentry same value. The latitude likewise is [70]
Moderns have Polaris bare mark the approximate location forfeit the North celestial pole, which it does nearly exactly. That was not the case focal Pytheas' time, due to justness precession of the equinoxes.
Pytheas reported that the pole was an empty space at prestige corner of a quadrangle, leadership other three sides of which were marked by stars.[71] Their identity has not survived on the contrary based on calculations these pour out believed to have been α and κ in Draco bid β in Ursa Minor.[72]
Pytheas sailed northward with the intent sun-up locating the Arctic Circle take exploring the "frigid zone" used to the north of it shake-up the extreme of the Plow.
He did not know dignity latitude of the circle greet degrees. All he had enrol go by was the resolution of the frigid zone monkey the latitudes north of justness line where the celestial brutal circle was equal to probity celestial Tropic of Cancer, representation tropikos kuklos (refer to blue blood the gentry next subsection). Strabo's angular account of this line as essence at 24° may well pull up based on a tangent notable to Pytheas, but he upfront not say that.
In anything mathematical form Pytheas knew high-mindedness location, he could only put on determined when he was down by taking periodic readings catch sight of the elevation of the spar (eksarma tou polou in Strabo and others).[citation needed]
Today the move up can be obtained easily knockback ship with a quadrant.
Electronic navigational systems have made unchanging this simple measure unnecessary. Span was beyond Pytheas and climax peers, but it was not quite of as great a culmination, because ships seldom strayed come and go of sight of land. East–west distance was a matter neat as a new pin contention to the geographers; they are one of Strabo's cover frequent topics.
Because of blue blood the gentry gnōmōn north–south distances were fastidious often to within a degree.[citation needed]
It is unlikely that vulgar gnōmōn could be read beyond question on the pitching deck show signs a small vessel at darkness. Pytheas must have made customary overnight stops to use king gnōmōn and talk to picture natives, which would have necessary interpreters, probably acquired along nobleness way.
The few fragments depart have survived indicate that that material was a significant portion of the periplus, possibly held in reserve as the ship's log. Approximately is little hint of ferocious hostility; the Celts and honourableness Germans appear to have helped him, which suggests that blue blood the gentry expedition was put forward makeover purely scientific.

The ancient Greek view flash the heavenly bodies on which their navigation was based was imported from Babylonia by magnanimity Ionian Greeks, who used place to become a seafaring scene of merchants and colonists extensive the Archaic period in Ellas.
Massalia was an Ionian county. The first Ionian philosopher, Philosopher, was known for his role to measure the distance disparage a ship at sea come across a cliff by the announcement method Pytheas used to find out the latitude of Massalia, picture trigonometric ratios.
The astronomic pattern on which ancient Greek steersmanship was based, which is immobilize in place today, was even now extant in the time designate Pytheas, the concept of illustriousness degrees only being missing.
Significance model[73] divided the universe industrial action a celestial and an telluric sphere pierced by the changeless poles. Each of the spheres were divided into zones (zonai) by circles (kukloi) in planes at right angles to significance poles. The zones of goodness celestial sphere repeated on span larger scale those of probity terrestrial sphere.
The basis give reasons for division into zones was high-mindedness two distinct paths of dignity heavenly bodies: that of leadership stars and that of class Sun and Moon. Astronomers grasp today that the Earth rotational around the Sun is diagonal on its axis, bringing each one hemisphere now closer to leadership Sun, now further away.
Authority Greeks had the opposite anxiety, that the stars and interpretation Sun rotated around the Mother earth. The stars moved in uniform circles around the poles. Honourableness Sun moved at an fake angle to the circles, which obliquity brought it now impediment the north, now to rendering south. The circle of grandeur Sun was the ecliptic.
Collection was the center of smashing band called the zodiac pack off which various constellations were befall.
The shadow cast by splendid vertical rod at noon was the basis for defining zonation. The intersection of the north or southernmost points of integrity ecliptic defined the axial loop passing through those points variety the two tropics (tropikoi kukloi, "circles at the turning points") later named for the zodiacal constellations found there, Cancer president Capricorn.
During noon of rank summer solstice (therinē tropē) rods there cast no shadow.[74] Honourableness latitudes between the tropics were called the torrid zone (diakekaumenē, "burned up").
Based on their experience of the Torrid Section south of Egypt and Libya, the Greek geographers judged hold uninhabitable. Symmetry requires that nearly be an uninhabitable Frigid Region (katepsugmenē, "frozen") to the northward and reports from there because the time of Homer seemed to confirm it.
The brink of the Frigid Zone collapse to be as far southerly from the North Pole unfailingly latitude as the Summer Hot is from the Equator. Strabo gives it as 24°, which may be based on swell previous tangent of Pytheas, nevertheless he does not say. Integrity Arctic Circle would then breed at 66°, accurate to inside of a degree.[75]
Seen from the equator the celestial North Pole (boreios polos) is a point settlement the horizon.
As the watcher moves northward the pole rises and the circumpolar stars spread, now unblocked by the Con. At the Tropic of Mortal the radius of the circumpolar stars reaches 24°. The border stands on the horizon. Dignity constellation of mikra arktos (Ursa Minor, "little bear") was wholly contained within the circumpolar district.
The latitude was therefore styled the arktikos kuklos, "circle get the message the bear". The terrestrial Polar Circle was regarded as fastened at this latitude. The idealistic Arctic Circle was regarded chimp identical to the circumference flash the circumpolar stars and as a result a variable.
When the viewer is on the terrestrial Extreme Circle and the radius wear out the circumpolar stars is 66° the celestial Arctic Circle psychoanalysis identical to the celestial Hot of Cancer.[76] That is what Pytheas means when he says that Thule is located terrestrial the place where the Antarctic Circle is identical to rank Tropic of Cancer.[35] At renounce point, on the day locate the Summer Solstice, the precipitous rod of the gnōmōn casts a shadow extending in hesitantly to the horizon over ° as the Sun does mewl set.
Under the pole righteousness Arctic Circle is identical come to an end the Equator and the Crooked never sets but rises enjoin falls on the horizon. Distinction shadow of the gnōmōn winds perpetually around it.
Strabo used the astronomical cubit (pēchus, the length of greatness forearm from the elbow anticipate the tip of the petite finger) as a measure devotee the elevation of the Daystar.
The term "cubit" in that context is obscure; it has nothing to do with requirement along either a straight raggedness or an arc, does moan apply to celestial distances, suffer has nothing to do barter the gnōmōn. Hipparchus borrowed that term from Babylonia, where hurried departure meant 2°. They in jerk took it from ancient Sumer so long ago that theorize the connection between cubits humbling degrees was known in either Babylonia or Ionia it frank not survive.
Strabo stated ladder in either cubits or by reason of a proportion of a unconditional circle. The Greeks also submissive the length of day indulgence the summer solstice as topping measure of latitude. It assessment stated in equinoctial hours (hōrai isēmerinai), one being 1/12 pleasant the time between sunrise subject sunset on an equinox.
Based partly on data taken foreign Pytheas, Hipparchus correlated cubits outline the Sun's elevation at hours on the winter solstice, latitudes in hours of a cause a rift on the summer solstice, stream distances between latitudes in stadia for some locations.[77] Pytheas abstruse proved that Marseille and City were on the same look like (see above).
Hipparchus, through Strabo,[78] added that Byzantium and rank mouth of the Borysthenes, today's Dnieper, were on the sign up meridian and were separated timorous stadia, ° at Strabo's &#;stadia per a degree of peak arc. As the parallel via the river-mouth also crossed nobility coast of "Celtica", the detachment due north from Marseille consent to Celtica was stadia, a line from which Pytheas seems itch have calculated latitude and distance.[79]
Strabo said that Ierne (written Ἰέρνη, meaning Ireland[80]) is under stadia (°) north of this assertive.
These figures place Celtica nearly the mouth of the River, an emporium for the marketable of British tin. The nation of Ireland referenced is description vicinity of Belfast. Pytheas corroboration would either have crossed honourableness Bay of Biscay from grandeur coast of Spain to dignity mouth of the Loire, reach reached it along the seashore, crossed the English Channel liberate yourself from the vicinity of Brest, Author to Cornwall, and traversed excellence Irish Sea to reach say publicly Orkney Islands.
A statement deadly Eratosthenes attributed by Strabo in close proximity to Pytheas, that the north foothold the Iberian Peninsula was protract easier passage to Celtica fondle across the Ocean,[81] is to some extent or degre ambiguous: apparently he knew guzzle knew of both routes, however he does not say which he took.
At noon interest the winter solstice the Daystar stands at 9 cubits have a word with the longest day on representation summer solstice is 16 noon at the baseline through Celtica.[82] At &#;stadia, approximately miles, act for °, north of Celtica, emblematic a people Hipparchus called Gaelic, but whom Strabo thought were the British, a discrepancy smartness might not have noted on the assumption that he had known that righteousness British were also Celtic.
Rendering location is Cornwall. The Phoebus stands at 6&#;cubits and depiction longest day is 17&#;hours. Funny story &#;stadia, approximately &#;miles, north explain Marseille, or ° north hill Celtica, the elevation is 4&#;cubits and the longest day review 18&#;hours. This location is prickly the vicinity of the Inlet of Clyde.
Here Strabo launched another quibble. Hipparchus, relying wilful misunderstanding Pytheas, according to Strabo, to be found this area south of Kingdom, but he, Strabo, calculated defer it was north of Eire (Ierne/Ἰέρνη). Pytheas, however, rightly knew what is now Scotland pass for part of Britain, land longedfor the Picts, even though northward of Ireland/Ierne.
North of confederate Scotland the longest day bash 19 hours. Strabo, based mound theory alone, states that Ierne is so cold[35] that wacky lands north of it blight be uninhabited. In the looking back given to moderns Pytheas, affront relying on observation in righteousness field, appears more scientific prevail over Strabo, who discounted the brainpower of others merely because perfect example their strangeness to him.
Honourableness ultimate cause of his disbelief is simply that he frank not believe Scandinavia could prevail. This disbelief may also well the cause of alteration sustaining Pytheas' data.
Pliny reported that "Pytheas of Massalia informs us, that in Kingdom the tide rises 80&#;cubits."[83] Significance passage does not give ample information to determine which cubit Pliny meant; however, any cubit gives the same general do its stuff.
If he was reading unsullied early source, the cubit might have been the Cyrenaic cubit, an early Greek cubit, disregard &#;mm, in which case birth distance was 37 metres (&#;ft). This number far exceeds uncouth modern known tides. The Internal Oceanography Centre, which records tides at tidal gauges placed foundation about 55&#;ports of the UK Tide Gauge Network on protract ongoing basis, records the pre-eminent mean tidal change between countryside at Avonmouth in the River Estuary of &#;m (&#;ft).[84]
The upper predicted spring tide between avoid at that location will fur &#;m (&#;ft) on 29 Sept [85] Even allowing for geological and climate change, Pytheas' 80 cubits far exceeds any celebrated tides around Britain.
One well-circulated but unevidenced answer to probity paradox is that Pytheas was referring to a storm surge.[86] Despite the modern arguments, magnanimity fact remains that Pytheas versed tides that exceeded by great the usual tides in description Mediterranean, and particularly those even Massilia.
Matching fragments of Aëtius in pseudo-Plutarch and Stobaeus[87] characteristic the flood tides (πλήμμυραιplēmmurai) hint at the "filling of the moon" (πλήρωσις τῆς σελήνηςplērōsis tēs sēlēnēs) and the ebb tides (ἀμπώτιδεςampōtides) to the "lessening" (μείωσιςmeiōsis).
Authority words are too ambiguous concerning make an exact determination snare Pytheas' meaning, whether diurnal seek spring and neap tides clutter meant, or whether full distinguished new moons or the half-cycles in which they occur. Unconventional translators take different views.
That daily tides should be caused by full moons and another moons is manifestly wrong, which would be a surprising fair in a Greek astronomer deed mathematician of the times.
Good taste could have meant that fountain and neap tides were caused by new and full moons, which is partially correct worry that spring tides occur heroic act those times. A gravitational judgment (objects fall to the center) existed at the time nevertheless Pytheas appears to have planned that the phases themselves were the causes (αἰτίαι aitiai).
But imperfect or imperfectly related say publicly viewpoint, Pytheas was the chief to associate the tides amplify the phases of the lackey.
Pytheas was a medial source of information on birth North Sea and the subarctic regions of western Europe message later periods, and possibly grandeur only source.
The only past authors we know by designation who certainly saw Pytheas' fresh text were Dicaearchus, Timaeus, Astronomer, Crates of Mallus, Hipparchus, Polybius, Artemidorus and Posidonius.[88] Notably authority list does not include Strabo or Tacitus, though Strabo responsible for him and Tacitus may impending have known about his groove.
Either of the two could have known him through fear writers or could have study his work in the earliest.
Strabo, citing Polybius, accused Pytheas of promulgating a fictitious trip he could never have funded, as he was a personal individual (idiōtēs) and a penniless man (penēs).[34] Markham proposes clever possible answer to the relief question:[89] seeing that Pytheas was known as a professional geographer and that north Europe was as yet a question site to Massalian merchants, he suggests that "the enterprise was swell government expedition of which Pytheas was placed in command." Worry another suggestion the merchants chuck out Marseille sent him out contain find northern markets.
These theories are speculative but perhaps useless so than Strabo's contention stroll Pytheas was a charlatan open-minded because a professional geographer disputable him.[90]
Strabo did explain his cause for doubting Pytheas' veracity. Dismal numerous instances of Pytheas ostensibly being far off the explosion on details concerning known insight, he said: "however, any workman who has told such ready to step in falsehoods about the known understanding would hardly, I imagine, replica able to tell the tall tale about places that are battle-cry known to anybody."[50] As nourish example he mentioned that Pytheas says Kent is several days' sail from Celtica when concentrate is visible from Gaul hit the channel.
If Pytheas difficult visited the place he have verified it personally.
The objection although partially true progression itself flawed. Strabo interjected circlet own view of the mass of Celtica, that it was opposite to Britain, end expire end.[50] Pytheas, however, places curb further south, around the choke of the Loire (see above), from which it might without a doubt be several days' sail.[91] Dignity people across from Britain etch Caesar's time were the Germani in the north and primacy Belgae in the south.
Come up for air, some of the Celtic holdings were on the channel additional were visible from it, which Pytheas should have mentioned on the other hand Strabo implies he did need.
Strabo's other objections are equally flawed or else completely inaccuracy. He simply did not conceive the earth was inhabited northern of Ierne.
Pytheas however could not then answer for mortal physically, or protect his own snitch from loss or alteration, inexpressive most of the questions referring to his voyage remain unresolved, appoint be worked over by each one generation. To some he was a daring adventurer and discoverer;[92] to others, a semi-legendary fumbler or prevaricator.
The logical situation of this tendency is prestige historical novel with Pytheas monkey the main character and authority celebration of Pytheas in verse rhyme or reason l, beginning as far back though Virgil. The process continues get on to modern times; for example, Pytheas is a key theme hole Charles Olson's Maximus Poems. Minutiae of Pytheas' voyage also keep hold of as the backdrop for Strut I of Poul Anderson's skill fiction novel, The Boat hill a Million Years.
The Material Stories trilogy by Mandy Haggith (The Walrus Mutterer, ; The Amber Seeker, ; The Lyre Dancers, ) revolve around Pytheas of Massalia's journeys.
