Polydectes

Polydectes was the son of either Magnes and an unnamed naiad,[1][2] or of Peristhenes and Androthoe,[3] or of Poseidon and Cerebia.

Polydectes fell in love with Danaë when she and her son Perseus were saved by his brother Dictys (see: Acrisius).

Under the pretense that he was going to marry Hippodamia, he ordered every man in Seriphos to supply him with suitable gifts.

When Perseus returned to Seriphos with the Gorgon's head, he found that, in his absence, his mother was threatened and abused by Polydectes, and had to seek refuge in a temple.

He did not abuse Perseus and Danae, but rather protected them from Acrisius as the latter discovered that they had survived and arrived at Seriphos to kill them.
