In Greek mythology, Agasthenes (Ancient Greek: Ἀγασθένης) was the son of Augeas, and his successor in the kingdom of Elis. The government was shared between Amphimachus, Thalpius and Agasthenes.[1] With Peloris, he was the father of Polyxenus, one of the "suitors of Helen", who reunified the kingdom when he returned from Troy.[2][3]
