Glaucus (son of Minos)

Glaucus (Greek: Γλαῦκος, English translation: "shiny", "bright" or "bluish-green") was a son of Minos and Pasiphaë. One day, Glaucus was playing with a ball or mouse and suddenly disappeared. His parents went to the Oracle at Delphi who told them "A marvelous creature has been born amongst you: whoever finds the true likeness for this creature will also find the child." They interpreted this to refer to a newborn calf in Minos' herd. Three times a day, the calf changed color from white to red to black. Polyidus observed the similarity to the ripening of the fruit of the mulberry (or possibly the blackberry) plant, and Minos sent him to find Glaucus.

Searching for the boy, Polyidus saw an owl driving bees away from a wine-cellar in Minos' palace. Inside the wine-cellar was a cask of honey, with Glaucus dead inside. Minos demanded Glaucus be brought back to life, though Polyidus objected. Minos was justified in his insistence, as the Delphic Oracle had said that the seer would restore the child alive. Minos shut Polyidus up in the wine-cellar with a sword. When a snake appeared nearby, Polyidus killed it with the sword. Another snake came for the first, and after seeing its mate dead, the second serpent left and brought back a herb which then brought the first snake back to life. Following this example, Polyidus used the same herb to resurrect Glaucus.

Minos refused to let Polyidus leave Crete until he taught Glaucus the art of divination. Polyidus did so, but then, at the last second before leaving, he asked Glaucus to spit in his mouth. Glaucus did so and forgot everything he had been taught. The story of Polyidus and Glaucus was the subject of a lost play attributed to Euripides. Glaucus later led an army that attacked Italy, introducing to them the military girdle and shield. This was the source of his Italian name, Labicus, meaning "girdled".
