In Greek mythology, Thalia or Thaleia (/ˈθeɪliə/^[1] or /θəˈlaɪə/;^[2] Ancient Greek: Θάλεια Tháleia, "the joyous, the abundance", from θάλλειν / thállein, "to flourish, to be green") was a nymph daughter of Hephaestus, and the mother of the Palici.^[3]

Macrobius's Saturnales (song V) states how Zeus made love to her near the river Symethe on Sicily. She buried herself in the ground to avoid Hera's jealousy. Her twin children, the Palici, were thus born under the earth,^[4] though other authors make the Palici the sons of Hephaestus or Adranus.
