In Greek mythology, Hermes gave Pandora her name and the gift of speech.
Hesiod’s Works and Days describes the gods contributing different qualities to the woman created at Zeus’s command. Hermes gives her a voice and names her Pandora. The name is conventionally connected with the idea that all the gods gave gifts to her, although its precise ancient interpretation has been discussed by scholars.
Hermes was the Olympian messenger and a god associated with communication, travel, trade, and transitions. His role in Pandora’s creation therefore fits the literary pattern in which each god contributes a characteristic power or quality.
Hephaestus is a common wrong answer because he physically fashioned Pandora. Zeus is another tempting choice because he planned the punishment. In Hesiod’s division of roles, however, Hermes is the figure associated with her naming and speech.
