That of Agamemnon is the most noted. Homer says it was made by Vulcan, who gave it to the son of Saturn. It then passed successively to Jupiter, to Mercury, to Pelops, to Atreus (2 syl.), to Thyestes (3 syl.), and then to Agamemnon. It was found at Phocis, whither it had been taken by Electra. It was looked on with great reverence, and several miracles are attributed to it. It was preserved for many years after the time of Homer, but ultimately disappeared.
