In Hesiod’s story, Hermes gave Pandora a deceptive mind and a cunning tongue.
Hermes was the messenger of the Greek gods and a deity associated with travel, trade, boundaries, cleverness, and trickery. In Works and Days, Zeus instructs Hermes to give Pandora a shameless mind and a deceitful nature, helping explain the danger attached to her arrival.
The detail belongs to the ancient literary version of the myth, not simply to later modern summaries. Pandora’s attributes are deliberately mixed: she receives beauty, skill, charm, and speech, but also qualities that make her dangerous within Hesiod’s strongly moralizing account.
Hermes is sometimes named as Pandora’s creator because he participates in her preparation. Hesiod, however, gives the physical making of her form to Hephaestus and the gift of deceptive speech to Hermes.
