Pierus of Magnesia

In Greek mythology, Pierus (Ancient Greek: Πίερος Píeros) was the son of Thessalian Magnes. He was the lover of muse Clio and father of Hyacinth in some accounts, and Rhagus.

Mythology
Pierus was loved by muse Clio because Aphrodite had inspired her with the passion, as a punishment for deriding the goddess' own love for Adonis. This was the only myth where Pierus appeared once:


 * "Clio fell in love with Pierus, son of Magnes, in consequence of the wrath of Aphrodite, whom she had twitted with her love of Adonis; and having met him she bore him a son Hyacinth.."
