In Hesiod’s account of Pandora, Hephaestus is credited with creating her body from earth.
Hephaestus, the Olympian god associated with fire, metalworking, and craftsmanship, shapes Pandora at Zeus’s command. Hesiod’s Works and Days describes the creation as an engineered divine act rather than a birth from human parents. Other gods then contribute qualities, skills, or deceptive characteristics.
This role fits Hephaestus’s traditional identity as the gods’ craftsman. In Greek mythology he makes armor, weapons, jewelry, and other extraordinary objects, so fashioning a human figure from earth is consistent with his literary portrayal.
Pandora’s creation is often simplified into a general statement that “the gods made her.” The more specific account distinguishes the maker of her physical form from the gods who add their gifts. That distinction is why Hephaestus is the precise answer to this question.
