Lycurgus was the son of Aleus, the previous ruler of Tegea, and Neaera, daughter of Pereus, and thus, brother to the Argonauts Amphidamas, Cepheus, Auge and Alcidice.
[1] He married either Cleophyle, Eurynome or Antinoe[2] and fathered these sons: Ancaeus,[3] Epochus, Amphidamas, and Iasius.
According to scholia on the Argonautica, Ereuthalion was also vanquished by Lycurgus, who laid an ambush against him and overcame him in the ensuing battle.
The Arcadians celebrated a feast known as Moleia in commemoration of this mythical event (mōlos being a word for "battle" according to the scholiast), and paid general honors to Lycurgus.
[2] Lycurgus outlived his sons and reached an extreme old age for Epochus fell ill and died while Ancaeus was wounded by the Calydonian boar.
