Glaucus in the ancient sources

That Glaucus was a fisherman, who, on eating of the grass, turned into a deity of the sea and ever since has foretold to men the future, is a belief generally accepted; in particular, seafaring men tell every year many a tale about the soothsaying of Glaucus. Pindar and Aeschylus got a story about Glaucus from the people of Anthedon .

Now the Euboean dweller in great waves, Glaucus, had left behind the crest of Aetna , raised upward from a giant's head; and left the Cyclops ' fields, that never had been torn by harrow or by plough and never were indebted to the toil of oxen yoked;

When they had thus spoken, the twain leapt down from their chariots and clasped each other's hands and pledged their faith. And then from Glaucus did Zeus, son of Cronos, take away his wit, seeing he made exchange of armour with Diomedes, son of Tydeus, giving golden for bronze, the worth of an hundred oxen for the worth of nine.
