According to Hesiod (Theogony 820-822), the monster Typhon was the offspring of Earth and Tartaros, born after the defeat of the Titans. Zeus attacked him with his thunderbolts and cast him into Tartaros, where he came to be associated with volcanic forces.
Hesiod describes him as having a hundred heads growing from his shoulders. In the Archaic Period, he is shown with a single bearded head and a winged torso tapering to the coil of a snake, as here. For other Corinthian alabastra depicting Typhon see nos. 1-10 in Touchefeu-Meynier, "Typhon" in LIMC.
