Polyeidus and Glaucus

Minos had a young son named Glaucus (Glaucos or Γλαὓκος) who fell into a large jar of honey. Minos told an Argive seer named Polyeidus (Polyidos or Πολύειn.δος), who was a descendant of Melampus (Melampous), to revive his son, so Minos had Polyeidus entombed with Glaucus.

In the tomb, Polyeidus killed a snake, but saw a second snake bringing back the dead snake to life with an herb. Polyeidus took some of the herb and revived the king's son.

Minos then ordered Polyeidus to teach Glaucus everything about the art of divination; otherwise he could not leave the island. So he taught the king's son everything he knew.

When Minos finally allowed the seer to leave, Polyeidus told the boy that he had one last lesson to teach him. Polyeidus told the boy to spit into his mouth. Once Glaucus spat into the seer's mouth, the boy forgot everything that Polyeidus had taught him.

While Polyeidus was in Lycia, it was he who gave Bellerophon his counsel on how to tame the winged horse Pegasus.
