Grecian Mythology, the wife of Cadmus, was the daughter of Mars and Venus, or, as others say, of Jupiter and Electra. On the day of her marriage all the gods came from Olympus to witness the ceremony. The necklace and the peplus, or robe, which her husband presented to her on that occasion obtained a sad renown in the old mythology, from the evils they brought upon all who wore them. Polynices, into whose hands it passed, Harmonica used it to bribe Eriphyle to disclose the retreat of her husband, Amphiarus, who had hidden himself that he might escape from the Theban expedition, in which it had been foretold that he would perish. He did perish, and his son Alcmenon, hearing how his fate had been accomplished, slew his mother Eriphyle. The fatal necklace next passed to Arsinoe, then to Pronous, and Agenor, and was finally dedicated in the temple of Minerva at Delphi by Amphoterus and Acarnan, the sons of Alcmenon. Even then, however, it did not lose its powers of working mischief. The tyrant Phyllus stole it from the temple, and gave it to his mistress, who wore it for a time. Her son, however, was struck with madness, and in a frenzy set fire to the house in which his mother was. She was burnt to death, and all her treasures were consumed in the same fire which destroyed herself.
