Answer:
1.After unsuccessful courting and consecutive denial by Danae, Polydectes thought that Perseus is the main obstacle for their marriage. The king therefore sent Perseus on a quest to bring the head of Medusa, thinking it would be his doom.
2.Later Perseus gave the Gorgon's head to Athena, who placed it on her shield, and gave his other accoutrements to Hermes. He accompanied his mother back to her native Argos, where he accidentally struck her father, Acrisius, dead when throwing the discus, thus fulfilling the prophecy that he would kill his grandfather.
3.Because the gaze of Medusa turned all who looked at her to stone, Perseus guided himself by her reflection in a shield given him by Athena and beheaded Medusa as she slept. He then returned to Seriphus and rescued his mother by turning Polydectes and his supporters to stone at the sight of Medusa's head.
4.From the Hesperides he received a knapsack (kibisis) to safely contain Medusa's head. Zeus gave him an adamantine sword (a Harpe) and Hades' helm of darkness to hide. Hermes lent Perseus winged sandals to fly, and Athena gave him a polished shield. Perseus then proceeded to the Gorgons' cave.
