In Hesiod’s account of Pandora, Hermes gave her a deceitful mind and lying nature. This detail appears in the Theogony, where the gods contribute different qualities to the woman created at Zeus’s command.
Pandora’s construction is presented as a collaborative divine project. Hephaestus forms her from earth, while other gods provide gifts or attributes associated with beauty, skill, charm, and speech. Hermes’s contribution is darker: he places in her a shameless mind and a lying nature, according to translations of Hesiod’s wording.
Hermes is best known in Greek mythology as a messenger, herald, guide, and god connected with trade and cunning. His role in Pandora’s creation emphasizes the story’s theme that her appearance and gifts conceal danger.
Translations differ in their exact wording, so readers may encounter “deceitful character,” “lying nature,” or similar phrases. The underlying attribution remains Hermes, not Zeus or Hephaestus.
