The ensuing years of prosperity and contentment for Perseus and Andromeda were somewhat marred by what happened next. Leaving the kindly fisherman Dictys on the throne of Seriphos, Perseus returned to his native city of Argos. His grandfather heard he was coming and, ever mindful of the oracle's prophesy, left town. Perseus innocently followed. Invited to partake in an athletic contest, he thrilled the crowd with his skill at the discus. Unfortunately the wind blew his shot astray and his grandfather, who had joined the audience, was struck in the head (or foot) and died. Eventually Athena immortalized Perseus by placing him in the sky as a constellation, together with Andromeda, her parents and the sea monster.
