Apollodorus Library 3.3.1

[1]
  To Deucalion were born Idomeneus and Crete and a bastard son Molus. ¹ But Glaucus, while he was yet a child, in chasing a mouse fell into a jar of honey and was drowned. ² On his disappearance Minos made a great search and consulted diviners as to how he should find him. The Curetes told him that in his herds he had a cow of three different colors, and that the man who could best describe that cow's color would also restore his son to him alive. ³ So when the diviners were assembled, Polyidus, son of Coeranus, compared the color of the cow to the fruit of the bramble, and being compelled to seek for the child he found him by means of a sort of divination. ⁴ But Minos declaring that he must recover him alive, he was shut up with the dead body. And while he was in great perplexity, he saw a serpent going towards the corpse. He threw a stone and killed it, fearing to be killed himself if any harm befell the body. ⁵ But another serpent came, and, seeing the former one dead, departed, and then returned, bringing a herb, and placed it on the whole body of the other; and no sooner was the herb so placed upon it than the dead serpent came to life. Surprised at this sight, Polyidus applied the same herb to the body of Glaucus and raised him from the dead. ⁶
