Deileon
Deileon (, Dēileōn) is a figure in Greek mythology. He was a son of Deimachus from Tricca in Thessaly. Along with his brothers, Autolycus and Phlogius, Deileon took part in the campaign of Hercules during the Amazon battles. These three brothers went astray and stayed at Sinope, where they later met the Argonauts and joined them on their expedition to Colchis. Plutarch mentioned him as Demoleon .
