His sandals, called pédila by the Greeks and talaria by the Romans, were made of palm and myrtle branches but were described as beautiful, golden and immortal, made a sublime art, able to take the roads with the speed of wind. Originally, they had no wings, but late in the artistic representations, they are depicted. In certain images, the wings spring directly from the ankles. Hermes has also been depicted with a purse or a bag in his hands, wearing a robe or cloak, which had the power to confer invisibility. His weapon was a sword of gold, which killed Argos; lent to Perseus to kill Medusa .
