This document provides a summary of the key events in the myth of Perseus and the Gorgon's head:
1) Perseus was born to Danae after Zeus visited her in a shower of gold, and they were set adrift in a chest by King Acrisius who feared an oracle's prophecy.
2) Perseus grew up with fisherman Dictys and was later sent by King Polydectes on a quest to kill the Gorgon Medusa.
3) With help from Athena and Hermes, Perseus obtained tools from the Graeae and nymphs to complete his quest, and used Athena's advice and his reflective shield to behead Medusa
