1. The son of Ninus, the first of the Lydian dynasty of the Heracleidae. The tradition was, that this dynasty supplanted a native race of kings, having been originally entrusted with the government as deputies. The names Ninus and Belus in their genealogy render it probable that they were either Assyrian governors, or princes of Assyrian origin, and that their accession marks the period of an Assyrian conquest. (Hdt. 1.7.)
