Phineus (son of Belus)
Phineus had been engaged to Cepheus' daughter Andromeda before she wed Perseus, and Phineus plotted against him, leading Perseus to turn him and his co-conspirators into stone by showing them the head of Medusa. The affair appears to have formed part of Euripides' lost Andromeda, but the sole extensive ancient treatment is found Ovid's Metamorphoses.
In Ovid's account Perseus asked for Andromeda's hand in return for saving the girl from the sea-monster Cetus to whom an oracle had ordained Andromeda be sacrificed as punishment for her mother Cassiopeia's boast that she was more beautiful than the Nereids. Perseus was successful, but as he recounted his deeds to the court of Cepheus a spear-brandishing Phineus assailed him:
"en" ait, 'en adsum praereptae coniugis ultor;
nec mihi te pennae nec falsum versus in aurum Iuppiter eripiet."
"See," he shouted "See, I come here as an avenger for the carrying off of my bride.
Your wings won't help you escape me, nor even Jupiter, changed to a shower of fool's gold!"
Phineus' presumed motive in marrying Andromeda was to strengthen his claim to the throne, rather than any interest in the girl herself. Cepheus scolded his brother for this outburst, pointing out that he had done nothing to help Andromeda in the crisis, but Phineus still cast his spear at Perseus. Although he missed, a fierce battle ensued in which many fell until Perseus, surrounded by the enemy, held up the head of the Gorgon, turning all but Phineus to stone. Amazed by this, Phineus pleaded for his life with his gaze averted, but Perseus approached him and held the head before his eyes, turning Phineus to stone.
