In Greek mythology, Hermes gave Pandora a dog-like mind, according to Hesiod’s Theogony. The image appears in Hesiod’s description of the qualities assigned to Pandora during her creation.
Hermes was the divine messenger and a god associated with travel, trade, boundaries, and cunning. In the creation account, he contributes speech and a disposition characterized in the poem through the comparison with a dog’s mind, reinforcing the story’s strongly hostile portrayal of Pandora.
Modern retellings often omit this exact detail or replace it with the simpler idea that Hermes gave Pandora speech. The two points are related but not identical: the poem attributes different qualities to Pandora through the participation of different gods.
