Agron of Lydia

Agron was a legendary king of Lydia who is named by Herodotus as the first of the Lydian Heraclid dynasty. His father is named by Herodotus as Ninus, the mythical founder of Nineveh and a descendant of Šanta, an Assyrian sun god
Before he assumed the throne, the ruling family had been the Maeonian line of Lydus, from whom the country's name was derived. According to Herodotus, the Heraclid dynasty in Lydia reigned continuously through 22 generations for 505 years. The last of the line was Candaules, whose date of death was, so Herodotus' computation suggests for Agron's accession.
