The Infant Bacchus (Dionysus) painting (c. 1505–1510) by Giovanni Bellini.

The Bibliotheca seems to be following Pherecydes, who relates how the infant Dionysus, god of the grapevine, was nursed by the rain-nymphs, the Hyades at Nysa. Young Dionysus was also said to have been one of the many famous pupils of the centaur Chiron. According to Ptolemy Chennus in the Library of Photius,

 “Dionysus was loved by Chiron, from whom he learned chants and dances, the bacchic rites and initiations.” ~~Diodorus Siculus
