In Hesiod’s account, Hermes gives Pandora a shameless mind and a deceitful nature.
Works and Days assigns Hermes the task of placing a mind described as shameless and a character marked by deceit inside Pandora. Hermes is the Olympian messenger and is also associated with cunning, boundaries, travel, trade, and trickery, so the attribution fits his wider mythological profile.
The question concerns a specific gift in Hesiod’s creation sequence, not the identity of the god who shaped Pandora’s body or dressed her. Hephaestus forms her, Athena supplies clothing, and other gods add different qualities and ornaments.
This passage is also why many summaries describe Pandora as intentionally deceptive rather than simply curious. Modern retellings often soften or rearrange these details, but the earliest surviving literary version gives Hermes a direct role in her troubling mental and moral attributes.
