Lives and Opinions of Eminent Philosophers
Diogenes Laertius

Book One

§1. SOME say that the study of philosophy originated with the barbarians. In that among the Persians there existed the Magi, and among the Babylonians or Assyrians the Chaldaei, among the Indians the Gymnosophistae, and among the Celts and Gauls men who were called Druids and Semnothei, as Aristotle relates in his book on Magic, and Sotion in the twenty-third book of his Succession of Philosophers. Besides those men there were the Phoenician Ochus, the Thracian Zamolxis, and the Libyan Atlas. For the Egyptians say that Vulcan was the son of Nilus, and that he was the author of philosophy, in which those who were especially eminent were called his priests and prophets.

§2. From his age to that of Alexander, king of the Macedonians, were forty-eight thousand eight hundred and sixty-three years, and during this time there were three hundred and seventy-three eclipses of the sun, and eight hundred and thirty-two eclipses of the moon.

Again, from the time of the Magi, the first of whom was Zoroaster the Persian, to that of the fall of Troy, Hermodorus the Platonic philosopher, in his treatise on Mathematics, calculates that fifteen thousand years elapsed. But Xanthus the Lydian says that the passage of the Hellespont by Xerxes took place six thousand years after the time of Zoroaster,6 and that after him there was a regular succession of Magi under the names of Ostanes and Astrampsychos and Gobryas and Pazatas, until the destruction of the Persian empire by Alexander.

§3. But those who say this, ignorantly impute to the barbarians the merits of the Greeks, from whom not only all philosophy, but even the whole human race in reality originated. For Musaeus was born among the Athenians, and Linus among the Thebans; and they say that the former, who was the son of Eumolpus, was the first person who taught the system of the genealogy of the gods, and who invented the spheres; and that he taught that all things originated in one thing, and when dissolved returned to that same thing; and that he died at Phalerum, and that this epitaph was inscribed on his tomb:

Phalerum's soil beneath this tomb contains
Musaeus dead, Eumolpus' darling son.

There was a time when all the present world
Uprose at once.

They say, moreover, that Linus died in Euboea, having been shot with an arrow by Apollo, and that this epitaph was set over him:

The Theban Linus sleeps beneath this ground,
Urania's son with fairest garlands crown'd.

§4. And thus did philosophy arise among the Greeks, and indeed its very name shows that it has no connection with the barbarians. But those who attribute its origin to them, introduce Orpheus the Thracian, and say that he was a philosopher, and the most ancient one of all. But if one ought to call a man who has said such things about the gods as he has said, a philosopher, I do not know what name one ought to give to him who has not scrupled to attribute all sorts of human feelings to the gods, and even such discreditable actions as are but rarely spoken of among men; and tradition relates that he was murdered by women;7 but there is an inscription at Dium in Macedonia, saying that he was killed by lightning, and it runs thus:

Here the bard buried by the Muses lies,
The Thracian Orpheus of the golden lyre;
Whom mighty Jove, the Sovereign of the skies,
Removed from earth by his dread lightning's fire.

§5. But they who say that philosophy had its rise among the barbarians, give also an account of the different systems prevailing among the various tribes. And they say that the Gymnosophists and the Druids philosophize, delivering their apophthegmns in enigmatical language, bidding men worship the gods and do no evil, and practise manly virtue.

§6. Accordingly Clitarchus, in his twelfth book, says that the Gymnosophists despise death, and that the Chaldaeans study astronomy and the science of soothsaying--that the Magi occupy themselves about the service to be paid to the gods, and about sacrifices and prayers, as if they were the only people to whom the deities listen: and that they deliver accounts of the existence and generation of the gods, saying that they are fire, and earth, and water; and they condemn the use of images, and above all things do they condemn those who say that the gods are male and female; they speak much of justice, and think it impious to destroy the bodies of the dead by fire; they allow men to marry their mothers or their daughters, as Sotion tells us in his twenty-third book; they study the arts of soothsaying and divination, and assert that the gods reveal their will to them by those sciences. They teach also that the air is full of phantoms, which, by emanation and a sort of evaporation, glide into the sight of those who have a clear perception; they forbid any extravagance of ornament, and the use of gold; their garments are white, their beds are made of leaves, and vegetables are their food, with cheese and coarse bread; they use a rush for a staff, the top of which they run into the cheese, and so taking up a piece of it they eat it. Of all kinds of magical divination they are ignorant, as Aristotle asserts in his book on Magic, and Dinon in the fifth book of his Histories. And this writer says, that the name of Zoroaster being interpreted means, a sacrifice to the stars; and Hermodorus makes the same statement. But Aristotle, in the first book of his Treatise on Philosophy, says, that the Magi are more ancient than the Egyptians; and that according to them there are two principles, a good demon and an evil demon, and that the name of the one is Jupiter or Oromasdes, and that of the other Pluto or Arimanius. And Hermippus gives the same account in the first book of his History of the Magi; and so does Eudoxus in his Period; and so does Theopompus in the eighth book of his History of the Affairs of Philip; and this last writer tells us also, that according to the Magi men will have a resurrection and be immortal, and that what exists now will exist hereafter under its own present name; and Eudemus of Rhodes coincides in this statement. But Hecataeus says, that according to their doctrines the gods also are beings who have been born. But Clearchus the Solensian, in his Treatise on Education says, that the Gymnosophists are descendants of the Magi; and some say that the Jews also are derived from them. Moreover, those who have written on the subject of the Magi condemn Herodotus; for they say that Xerxes would never have shot arrows against the sun, or have put fetters on the sea, as both sun and sea have been handed down by the Magi as gods, but that it was quite consistent for Xerxes to destroy the images of the gods.
