In Hesiod’s account of Pandora, Hermes gave her persuasive speech and deceitful words. The detail appears in Hesiod’s description of the gods’ contributions to the woman created as Zeus’s punishment for humanity.
Hermes is especially fitting for this role because Greek mythology associates him with communication, cunning, trade, travel, and trickery. Hesiod describes him placing in Pandora’s breast a deceptive mind and a thievish character, helping explain why she becomes a dangerous gift rather than a simply beautiful one.
This detail is easy to confuse with the other divine gifts in the story. Athena gives Pandora practical skills, while Aphrodite contributes charm and desire. Hephaestus fashions her, but Hermes supplies the qualities connected with speech and deception. These roles come from Hesiod’s poetic account, not from one single standardized later version of the myth.
