Polydektes was the king of Seriphos. Polydectes desired to marry Danae and become Perseus' father. Perseus, having no gold or treasures to give as a wedding gift, promised to bring the head of Medusa, one of the gorgons. Perseus returned with the head. Polydektes not believing that such a task could be done was skeptical of what was in Perseis' sack and upon looking at the head Polydectes was turned to stone.
