Hermes vs Mercury

Is Mercury the same as Hermes? In myth, yes — Virgil's Mercury binds on the golden sandals and takes up the sleep-giving wand in the very words Homer gives Hermes, and Ovid's Mercury slays Argus, the deed behind Hermes's Homeric epithet. The Roman surplus is genealogical: Virgil makes Mercury the ancestor of Evander, the Arcadian king on the Palatine.
