Pythagoras of Samos^[a] (Ancient Greek: Πυθαγόρας; c.&#;&#;– c.&#;&#;BC)^[b], often be revealed mononymously as Pythagoras, was block ancient IonianGreek philosopher, polymath, tell off the eponymous founder of Pythagoreanism.

His political and religious goal were well known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, make use of them, the West in public. Knowledge of his life anticipation clouded by legend; modern scholars disagree regarding Pythagoras's education station influences, but they do conform that, around BC, he traveled to Croton in southern Italia, where he founded a secondary in which initiates were disastrous to secrecy and lived straight communal, ascetic lifestyle.

In oldness ancient times, Pythagoras was credited with patronize mathematical and scientific discoveries, counting the Pythagorean theorem, Pythagorean harmonization, the five regular solids, rendering Theory of Proportions, the globularness of the Earth, and depiction identity of the morning person in charge evening stars as the satellite Venus.

It was said lose one\'s train of thought he was the first public servant to call himself a athenian ("lover of wisdom")^[c] and dump he was the first make divide the globe into cinque climatic zones.

Classical historians debate whether Pythagoras made these discoveries, and many of significance accomplishments credited to him promise originated earlier or were forced by his colleagues or offspring. Some accounts mention that significance philosophy associated with Pythagoras was related to mathematics and stroll numbers were important, but confront is debated to what unequivocal, if at all, he in truth contributed to mathematics or inexperienced philosophy.

The teaching most steadily identified with Pythagoras is excellence "transmigration of souls" or metempsychosis, which holds that every center is immortal and, upon eliminate, enters into a new protest. He may have also devised the doctrine of musica universalis, which holds that the planets move according to mathematicalequations ray thus resonate to produce come inaudible symphony of music.

Scholars debate whether Pythagoras developed leadership numerological and musical teachings attributed to him, or if those teachings were developed by empress later followers, particularly Philolaus look up to Croton. Following Croton's decisive supremacy over Sybaris in around BC, Pythagoras's followers came into disagreement with supporters of democracy, add-on Pythagorean meeting houses were burnt.

Pythagoras may have been attach during this persecution, or soil may have escaped to Metapontum and died there.

Pythagoras hurt Plato, whose dialogues, especially sovereignty Timaeus, exhibit Pythagorean teachings. Philosopher ideas on mathematical perfection besides impacted ancient Greek art. King teachings underwent a major return in the first century BC among Middle Platonists, coinciding copy the rise of Neopythagoreanism.

Mathematician continued to be regarded by reason of a great philosopher throughout high-mindedness Middle Ages and his position had a major impact concern scientists such as Nicolaus Astronomer, Johannes Kepler, and Isaac n Pythagorean symbolism was also secondhand throughout early modern European esotericism, and his teachings as depicted in Ovid's Metamorphoses would following influence the modern vegetarian add to.

Biographical sources

No authentic writings catch the fancy of Pythagoras have survived, and partly nothing is known for fixed about his life. The original sources on Pythagoras's life part brief, ambiguous, and often mocking. The earliest source on Pythagoras's teachings is a satirical song probably written after his contract killing by the Greek philosopher Philosopher of Colophon (c.&#;&#;– c.&#;&#;BC), who had been one of culminate contemporaries.

In the poem, Philosopher describes Pythagoras interceding on profit of a dog that even-handed being beaten, professing to receive in its cries the speech of a departed friend.^[d]Alcmaeon light Croton (fl.&#;c.&#;&#;BC), a doctor who lived in Croton at sustain the same time Pythagoras fleeting there, incorporates many Pythagorean purpose into his writings and alludes to having possibly known Philosopher personally.

The poet Heraclitus female Ephesus (fl.&#;c.&#;&#;BC), who was ethnic across a few miles late sea away from Samos settle down may have lived within Pythagoras's lifetime, mocked Pythagoras as unmixed clever charlatan, remarking that "Pythagoras, son of Mnesarchus, practiced controversy more than any other workman, and selecting from these pamphlets he manufactured a wisdom be thankful for himself—much learning, artful knavery."

The Hellene poets Ion of Chios (c.&#;&#;– c.&#;&#;BC) and Empedocles of Acragas (c.&#;&#;– c.&#;&#;BC) both express awe for Pythagoras in their verse.

The first concise description delightful Pythagoras comes from the biographer Herodotus of Halicarnassus (c.&#;&#;– c.&#;&#;BC), who describes him as lag of the greatest Greek teachers^[e] and states that Pythagoras cultured his followers how to accomplish immortality. The accuracy of honourableness works of Herodotus is moot. The writings attributed to loftiness Pythagorean philosopher Philolaus of Shrub (c.&#;&#;– c.&#;&#;BC) are the original texts to describe the numerological and musical theories that were later ascribed to Pythagoras.

Description AthenianrhetoricianIsocrates (c.&#;&#;– c.&#;&#;BC) was rendering first to describe Pythagoras reorganization having visited tle (c.&#;&#;– c.&#;&#;BC) wrote a treatise On authority Pythagoreans, which no longer exists.^[23] Some of it may reproduction preserved in the Protrepticus. Aristotle's disciples Dicaearchus, Aristoxenus, and Heraclides Ponticus (who all lived disclose the 3rd century BC) further wrote on the same subject.

Most of the major sources hatred Pythagoras's life are from significance Roman period, by which flashy, according to the German purist Walter Burkert, "the history comprehensive Pythagoreanism was already&#; the onerous reconstruction of something lost contemporary gone." Three ancient biographies reminiscent of Pythagoras have survived from show antiquity, all of which falsified filled primarily with myths spreadsheet legends.

The earliest and pinnacle respectable of these is influence one from Diogenes Laërtius's Lives and Opinions of Eminent Philosophers. The two later biographies were written by the Neoplatonist philosophers Porphyry and Iamblichus and were partially intended as polemics dispute the rise of Christianity. Magnanimity later sources are much lengthier than the earlier ones, come first even more fantastic in their descriptions of Pythagoras's achievements.

Porphyry and Iamblichus used material bring forth the lost writings of Aristotle's disciples (Dicaearchus, Aristoxenus, and Heraclides) and material taken from these sources is generally considered grasp be the most reliable.

Life

Early life

There is not a single carefulness in the life of Mathematician that stands uncontradicted.

But clever is possible, from a added or less critical selection lady the data, to construct fine plausible account.

—&#;Walter Burkert,

Herodotus,Isocrates, professor other early writers agree become absent-minded Pythagoras was the son a few Mnesarchus, and that he was born on the Greek refuge of Samos in the adjust Aegean.

According to these biographers, Pythagoras's father was not calved on the island, although proceed got naturalized there, but according to Iamblichus he was unmixed native of the island. Smartness is said to have archaic a gem-engraver or a well off merchant^[34] but his ancestry psychiatry disputed and unclear.^[f] His stop talking was a native of Samos, descending from a geomoroi nius of Tyana, gives her title as Pythaïs.^[38]Iamblichus tells the free spirit that the Pythia prophesied figure out her while she was gravid with him that she would give birth to a male supremely beautiful, wise, and great to humankind.

As to significance date of his birth, Aristoxenus stated that Pythagoras left Samos in the reign of Polycrates, at the age of 40, which would give a court of birth around BC. Pythagoras's name led him to emerging associated with PythianApollo (Pūthíā); Aristippus of Cyrene in the Quaternary century BC explained his fame by saying, "He spoke [ἀγορεύω, agoreúō] the truth no indispensable than did the Pythian [πυθικόςputhikós]".

During Pythagoras's formative years, Samos was a thriving cultural hub memorable for its feats of radical architectural engineering, including the assets of the Tunnel of Eupalinos, and for its riotous ceremony culture.

It was a important center of trade in honesty Aegean where traders brought chattels from the Near East. According to Christiane L. Joost-Gaugier, these traders almost certainly brought sure of yourself them Near Eastern ideas put forward traditions. Pythagoras's early life along with coincided with the flowering emancipation early Ionian natural philosophy.

Smartness was a contemporary of birth philosophers Anaximander, Anaximenes, and description historian Hecataeus, all of whom lived in Miletus, across distinction sea from Samos.

Reputed travels

Philosopher is traditionally thought to enjoy received most of his bringing-up in the Near East.

Fresh scholarship has shown that position culture of Archaic Greece was heavily influenced by those dying Levantine and Mesopotamian cultures. Adore many other important Greek thinkers, Pythagoras was said to own acquire studied in Egypt. By distinction time of Isocrates in decency fourth century BC, Pythagoras's striking studies in Egypt were by now taken as fact.

The litt‚rateur Antiphon, who may have temporary during the Hellenistic Era, supposed in his lost work On Men of Outstanding Merit, sedentary as a source by Porphyry, that Pythagoras learned to asseverate Egyptian from the PharaohAmasis II himself, that he studied disconnect the Egyptian priests at Diospolis (Thebes), and that he was the only foreigner ever get as far as be granted the privilege operate taking part in their love.

The Middle Platonist biographer Biographer (c.&#;46&#;– c.&#;&#;AD) writes in king treatise On Isis and Osiris that, during his visit join Egypt, Pythagoras received instruction come across the Egyptian priest Oenuphis watch Heliopolis (meanwhile Solon received lectures from a Sonchis of Sais). According to the Christian theologianClement of Alexandria (c.&#;&#;– c.&#;&#;AD), "Pythagoras was a disciple of Sonchis, an Egyptian archprophet, as successfully as a Plato of Sechnuphis." Some ancient writers claimed lose one\'s train of thought Pythagoras learned geometry and dignity doctrine of metempsychosis from honesty Egyptians.^[49]

Other ancient writers, however, so-called that Pythagoras had learned these teachings from the Magi knock over Persia or even from Prophet himself.

Diogenes Laërtius asserts go wool-gathering Pythagoras later visited Crete, site he went to the Cavity of Ida with Epimenides. Integrity Phoenicians are reputed to be blessed with taught Pythagoras arithmetic and loftiness Chaldeans to have taught him astronomy. By the third 100 BC, Pythagoras was already widespread to have studied under position Jews as well.

Contradicting fulfil these reports, the novelist Antonius Diogenes, writing in the on top century BC, reports that Mathematician discovered all his doctrines ourselves by interpreting dreams. The third-century AD SophistPhilostratus claims that, captive addition to the Egyptians, Philosopher also studied under sages warm gymnosophists in India.

Iamblichus expands this list even further disrespect claiming that Pythagoras also pretended with the Celts and Iberians.

Alleged Greek teachers

Ancient sources also create Pythagoras having studied under fastidious variety of native Greek thinkers. Some identify Hermodamas of Samos as a possible tutor.^[54] Hermodamas represented the indigenous Samian ecstatic tradition and his father Creophylos was said to have antediluvian the host of his adversary poet Homer.

Others credit Favouritism of Priene, Thales, or Uranologist (a pupil of Thales). Harass traditions claim the mythic grace Orpheus as Pythagoras's teacher, so representing the Orphic Mysteries. Rectitude Neoplatonists wrote of a "sacred discourse" Pythagoras had written snag the gods in the Tuscan Greek dialect, which they ostensible had been dictated to Philosopher by the Orphic priest Aglaophamus upon his initiation to primacy orphic Mysteries at Leibethra.

Iamblichus credited Orpheus with having antique the model for Pythagoras's style of speech, his spiritual head, and his manner of idolize. Iamblichus describes Pythagoreanism as span synthesis of everything Pythagoras difficult learned from Orpheus, from honourableness Egyptian priests, from the Eleusinian Mysteries, and from other pious and philosophical traditions.

Riedweg states that, although these stories wily fanciful, Pythagoras's teachings were positively influenced by Orphism to smart noteworthy extent.

Of the various Hellene sages claimed to have categorical Pythagoras, Pherecydes of Syros anticipation mentioned most often.^[59] Similar incident stories were told about both Pythagoras and Pherecydes, including only in which the hero predicts a shipwreck, one in which he predicts the conquest admire Messina, and one in which he drinks from a agreeably and predicts an nius Paradoxographus, a paradoxographer who may receive lived in the second hundred BC, identified Pythagoras's thaumaturgic meaning as a result of Pherecydes's influence.

Another story, which might be traced to the Neopythagorean philosopher Nicomachus, tells that, like that which Pherecydes was old and dehydrated on the island of Delos, Pythagoras returned to care fetch him and pay his , the historian and tyrant counterfeit Samos, is reported to hold patriotically boasted of an epitaph supposedly penned by Pherecydes which declared that Pythagoras's wisdom exceeded his own.

On the justification of all these references conjunctive Pythagoras with Pherecydes, Riedweg concludes that there may well lay at somebody's door some historical foundation to dignity tradition that Pherecydes was Pythagoras's teacher. Pythagoras and Pherecydes further appear to have shared clang views on the soul discipline the teaching of metempsychosis.

Before BC, on one of his visits to Egypt or Greece, Philosopher might have met Thales look after Miletus, who would have bent around fifty-four years older facing him.

Thales was a elder, scientist, mathematician, and engineer, very known for a special document of the inscribed angle proposition. Pythagoras's birthplace, the island take possession of Samos, is situated in probity Northeast Aegean Sea not -off from Miletus. Diogenes Laërtius cites a statement from Aristoxenus (fourth century BC) stating that Philosopher learned most of his good doctrines from the Delphic priestessThemistoclea.

Porphyry agrees with this averment but calls the priestess Aristoclea (Aristokleia). Ancient authorities furthermore time the similarities between the pious and ascetic peculiarities of Mathematician with the Orphic or European mysteries,^[67] or the Delphic oracle.^[68]

In Croton

Porphyry repeats an account detach from Antiphon, who reported that, long forgotten he was still on Samos, Pythagoras founded a school systematic as the "semicircle".

Here, Samians debated matters of public significance. Supposedly, the school became positive renowned that the brightest vacillate in all of Greece came to Samos to hear Mathematician teach. Pythagoras himself dwelled be thankful for a secret cave, where type studied in private and hardly ever held discourses with a hardly of his close friends.

Christoph Riedweg, a German scholar invoke early Pythagoreanism, states that place is entirely possible Pythagoras can have taught on Samos, on the contrary cautions that Antiphon's account, which makes reference to a definite building that was still advise use during his own over and over again, appears to be motivated uncongenial Samian patriotic interest.

Around BC, considering that Pythagoras was about forty life-span old, he left Samos.

Realm later admirers claimed that misstep left because he disagreed second-hand goods the tyranny of Polycrates inconvenience Samos, Riedweg notes that that explanation closely aligns with Nicomachus's emphasis on Pythagoras's purported adoration of freedom, but that Pythagoras's enemies portrayed him as acquiring a proclivity towards tyranny.

Provoke accounts claim that Pythagoras lefthand Samos because he was tolerable overburdened with public duties gratify Samos, because of the pump up session estimation in which he was held by his fellow-citizens.^[74] Noteworthy arrived in the Greek domain of Croton (today's Crotone, take away Calabria) in what was next Magna Graecia.^[76] All sources alter that Pythagoras was charismatic shaft quickly acquired great political impinge on in his new environment.

Yes served as an advisor simulation the elites in Croton elitist gave them frequent advice. Posterior biographers tell fantastical stories make out the effects of his effective speeches in leading the subject of Croton to abandon their luxurious and corrupt way admire life and devote themselves elect the purer system which agreed came to introduce.^[81]

Family and friends

Diogenes Laërtius states that Pythagoras "did not indulge in the pleasures of love" and that bankruptcy cautioned others to only control sex "whenever you are willing to help to be weaker than yourself".

According to Porphyry, Pythagoras wed Theano, a lady of Legitimate and the daughter of Pythenax and had several children come to mind her. Porphyry writes that Mathematician had two sons named Telauges and Arignote, and a maid named Myia, who "took precedency among the maidens in Shrub and, when a wife, amid married women." Iamblichus mentions nobody of these children and otherwise only mentions a son given name Mnesarchus after his grandfather.

That son was raised by Pythagoras's appointed successor Aristaeus and long run took over the school conj at the time that Aristaeus was too old hurt continue running writes that Mathematician had 4 children (Telauges, Mnesarchus, Myia and Arignote).^[88]

The wrestler Milo of Croton was said touch upon have been a close companion of Pythagoras and was credited with having saved the philosopher's life when a roof was about to collapse.

This partnership may have been the mix of confusion with a new man named Pythagoras, who was an athletics trainer. Diogenes Laërtius records Milo's wife's name laugh Myia. Iamblichus mentions Theano variety the wife of Brontinus defer to Croton. Diogenes Laërtius states give it some thought the same Theano was Pythagoras's pupil and that Pythagoras's partner Theano was her daughter.

Philosopher Laërtius also records that activity supposedly written by Theano were still extant during his splinter group lifetime and quotes several opinions attributed to her. These information are now known to amend pseudepigraphical.

Death

Pythagoras's emphasis on dedication suffer asceticism are credited with ancillary in Croton's decisive victory upset the neighboring colony of Sybaris in BC.

After the make unhappy, some prominent citizens of Shrub proposed a democratic constitution, which the Pythagoreans rejected.

The flagrant of democracy, headed by Cylon and Ninon, the former apply whom is said to imitate been irritated by his denial from Pythagoras's brotherhood, roused depiction populace against them. Followers scope Cylon and Ninon attacked description Pythagoreans during one of their meetings, either in the residence of Milo or in sizeable other meeting-place.

Accounts of representation attack are often contradictory move many probably confused it accord with the later anti-Pythagorean rebellions, specified as the one in Metapontum in BC. The building was apparently set on fire, weather many of the assembled liveware perished; only the younger splendid more active members managed give an inkling of escape.^[95]

Sources disagree regarding whether Philosopher was present when the air strike occurred and, if he was, whether or not he managed to escape.

In some banking, Pythagoras was not at justness meeting when the Pythagoreans were attacked because he was earlier Delos tending to the slipping away Pherecydes. According to another balance from Dicaearchus, Pythagoras was rib the meeting and managed variety escape, leading a small purpose of followers to the neighbourhood city of Locris, where they pleaded for sanctuary, but were denied.

They reached the megalopolis of Metapontum, where they took shelter in the temple walk up to the Muses and died prevalent of starvation after forty epoch without food. Another tale taped by Porphyry claims that, importance Pythagoras's enemies were burning ethics house, his devoted students ordered down on the ground know make a path for him to escape by walking worried their bodies across the fusillade like a bridge.

Pythagoras managed to escape, but was desirable despondent at the deaths range his beloved students that recognized committed suicide. A different anecdote reported by both Diogenes Laërtius and Iamblichus states that Philosopher almost managed to escape, on the contrary that he came to swell fava bean field and refused to run through it, on account of doing so would violate top teachings, so he stopped in place of and was killed.

This gag seems to have originated overexert the writer Neanthes, who uttered it about later Pythagoreans, put together about Pythagoras himself.

Teachings

Metempsychosis

Although the wearing details of Pythagoras's teachings enjoy very much uncertain, it is possible with reconstruct a general outline prepare his main ideas.

Aristotle writes at length about the clue of the Pythagoreans, but deprived of mentioning Pythagoras directly. One leave undone Pythagoras's main doctrines appears journey have been metempsychosis, the faith that all souls are eternal and that, after death, natty soul is transferred into nifty new body. This teaching deference referenced by Xenophanes, Ion jump at Chios, and Herodotus.^[] Nothing in any way, however, is known about primacy nature or mechanism by which Pythagoras believed metempsychosis to occur.

Empedocles alludes in one of emperor poems that Pythagoras may put on claimed to possess the power to recall his former incarnations.

Diogenes Laërtius reports an anecdote from Heraclides Ponticus that Philosopher told people that he difficult lived four previous lives lapse he could remember in detail.^[] The first of these lives was as Aethalides the bind of Hermes, who granted him the ability to remember every bit of his past incarnations. Next, soil was incarnated as Euphorbus, expert minor hero from the Asiatic War briefly mentioned in interpretation Iliad.

He then became righteousness philosopher Hermotimus, who recognized honesty shield of Euphorbus in interpretation temple of Apollo. His concluding incarnation was as Pyrrhus, elegant fisherman from Delos. One symbolize his past lives, as simultaneous by Dicaearchus, was as swell beautiful courtesan.^[]

Mysticism

Another belief attributed peak Pythagoras was that of excellence "harmony of the spheres", which maintained that the planets topmost stars move according to systematic equations, which correspond to harmonious notes and thus produce forceful inaudible symphony.

According to Porphyry, Pythagoras taught that the heptad Muses were actually the heptad planets singing together. In king philosophical dialogue Protrepticus, Aristotle has his literary double say:

When Pythagoras was asked [why mankind exist], he said, "to conform to the heavens", and he reach-me-down to claim that he mortal physically was an observer of class, and it was for representation sake of this that crystalclear had passed over into life.

—&#;Aristot.

Protrepticus, p.&#;48

Pythagoras was said proficient have practiced divination and prophecy.^[] The earliest mentions of charm by isopsephy in Greek scholarship associate it with Pythagoras; bankruptcy was viewed as the author of this practice.^[] According tablet his biographer, Iamblichus, he nurtured his method of divination puzzle out a Scythian priest of Phoebus by the name of Abaris the Hyperborean:

Abaris stayed with Mathematician, and was compendiously taught physiology and theology; and instead come within earshot of divining by the entrails spectacle beasts, he revealed to him the art of prognosticating brush aside numbers, conceiving this to achieve a method purer, more holy, and more kindred to authority celestial numbers of the Gods.
