Glaucus' mother was Queen Pasiphaë, daughter of Helios, and thus, brother to Acacallis, Ariadne, Androgeus, Deucalion, Phaedra, Xenodice, and Catreus.

One day, while playing with a ball[1] or chasing a mouse[2] Glaucus fell into a jar of honey and died.

Polyidus (or Asclepius, god of medicine) observed the similarity to the ripening of the fruit of the mulberry 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.

Glaucus had a daughter called Deiphobe, who was a priestess of Phoebus Apollo and Diana Trivia who features in The Aeneid in Book 6.
