In Greek mythology, Pandora was created from clay by the god Hephaestus.
Hesiod describes Zeus ordering Hephaestus to shape Pandora from earth or clay and give her a human form. Hephaestus, the divine smith and craftsman, is therefore responsible for making her physical body. Other gods then contribute attributes, clothing, adornment, or abilities.
This creation scene connects Pandora with a broader ancient motif in which humans are fashioned from earth. It also parallels the role of Hephaestus as a maker of extraordinary objects and figures for the gods.
Some retellings simplify the episode by saying only that the gods created Pandora. The more specific answer is Hephaestus’s clay craftsmanship, followed by the gifts supplied by the other deities.
