According to Hesiod, Hephaestus fashioned Pandora’s body from earth at Zeus’s command. Hephaestus is the Greek god of metalworking, craftsmanship, fire, and divine manufacture.
The creation scene appears in Hesiod’s Works and Days. Zeus tells Hephaestus to make a woman whose form resembles the immortal goddesses. Hephaestus uses earth or clay as the material, giving the episode a crafted, artificial quality rather than presenting Pandora as naturally born.
Other gods then contribute attributes or gifts. Athena teaches practical skills, Aphrodite gives beauty and desire, and Hermes supplies qualities associated with speech and deception in Hesiod’s account. The gods’ collective contributions explain the name Pandora, “All-gifted.”
This answer differs from the question of who created Pandora’s appearance in later retellings. Hephaestus is the divine artisan who constructs the body, while Zeus is the god who orders the project and directs its purpose.
