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.

Glaucus later led an army that attacked Italy, introducing to them the military girdle and shield.

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