Answer: BTW, this is if you are talking about Greek Mythology and not Percy Jackson(:D) You should totally read Percy Jackson and the Olympians by Rick Riordan! It can maybe help you in this subject. Trust me, the book is amazing and not even boring. Here's the answer, though:
The weapons Perseus received consisted of a knapsack to hold Medusa's head, an adamantine sword, Hades' helm of darkness, a pair of winged sandals, and a polished shield. The helm of darkness would keep Perseus invisible to the world and the winged sandals would allow him to fly.
