In Greek mythology, Harmonia is the goddess of harmony and concord. She is the daughter of Ares and Aphrodite (other sources say Zeus and Electra). She was married to the Theban ruler Cadmus, and as such was beloved by the Thebans. Upon her wedding she received a necklace and a garment, which proved fatal to who wished to possess them. Harmonia is the mother of Ino and Semele.
