The Gorgon

Clearly, then, Perseus had his work cut out for him. Fortunately he had an ally in Athena. The goddess of crafts and war had her own reasons for wishing to see the Gorgon vanquished, so she was eager to advise Perseus. Why, exactly, Athena had it in for Medusa is not entirely clear. The likeliest explanation is that the Gorgon, while still a beautiful young maiden, had profaned one of Athena's temples. For this sacrilege Athena turned her into a monster, but apparently this wasn't punishment enough.
