Harmonia

[1] By another account, Harmonia was from Samothrace and was the daughter of Zeus and Electra, her brothers were Dardanus and Iasion being the founder of the mystic rites celebrated on the island.

[6] Harmonia is renowned in ancient story chiefly on account of the fatal necklace she received on her wedding day.

[2] Other traditions stated that Harmonia received this necklace (ὅρμος) from some of the gods, either from Aphrodite or Athena.

[8] Polynices, who inherited the necklace, gave it to Eriphyle, that she might persuade her husband, Amphiaraus, to undertake the expedition against Thebes.

Phayllus, the tyrant, stole it from the temple to gratify his mistress, who is married to Ariston.

She wore it for a time, but at last her youngest son was seized with madness, and set fire to the house, in which she perished with all her treasures.

Harmonia is also rationalized as closely allied to Aphrodite Pandemos, the love that unites all people, the personification of order and civic unity, corresponding to the Roman goddess Concordia.
