At length Perseus found the nymphs in Hades, bathing in the river Styx, and got the gear. This consisted of the helmet of invisibility, winged sandals and a special pouch for carrying Medusa's head once he'd chopped it off. Medusa would retain the power of her gaze even in death, and it was vital to hide the head unless occasion called for whipping it out and using it on some enemy. The god Hermes also helped out at this point, providing Perseus with a special cutting implement, a sword or sickle of adamant. Some add that it was Hermes, not the nymphs, who provided the winged sandals.
