In Hesiod’s myth of Pandora, Hephaestus shaped her body from earth at Zeus’s command.
Hesiod describes Pandora’s creation in both the Theogony and Works and Days. Zeus ordered Hephaestus, the divine smith, to make a woman from earth as part of his punishment of humanity after Prometheus stole fire. The other gods then contributed qualities or gifts, giving her the name Pandora, commonly understood as “all-gifted.”
Hephaestus is especially associated with craftsmanship, metalworking, and the creation of divine objects. His role here does not mean that Pandora was made entirely from metal; Hesiod’s account says she was formed from earth and given human shape. Other gods supplied clothing, adornment, speech, and talents.
The myth is sometimes simplified into the claim that Zeus personally made Pandora. In Hesiod’s narrative, Zeus orders the creation, but Hephaestus performs the shaping. This distinction makes Hephaestus the specific answer to the question.
