In myth, daughter of Cepheus, king of Ethiopia, and his wife Cassiepeia. Cassiepeia boasted that she was more beautiful than the Nereids; they complained to Poseidon, who flooded the land and sent a sea‐monster to ravage it. On consulting Ammon, Cepheus learned that the only cure was to offer up Andromeda to the monster, and so she was fastened to a rock on the sea‐shore. At this point Perseus came by on his way from taking the head of the Gorgan Medusa. He fell in love with Andromeda, and got her and her father's consent to his marrying her if he could kill the monster. This he did; but Cepheus' brother Phineus, who had been betrothed to Andromeda, plotted against him. Perseus showed him and his followers the head of Medusa, turning them all to stone. He and Andromeda stayed for a time with Cepheus, and left their eldest son, Perses, with him; from Perses the Persian kings were descended. They then went on to Seriphus, then to Argos and Tiryns. Andromeda, Perseus, Cepheus, Cassiepeia, and the monster were all turned into constellations bearing their names (the monster is Cetus).
