Oncius

In Greek mythology, Oncius[pronunciation?] (Ancient Greek: Ὄγκιος, romanizedÓnkios, lit.'case for arrowheads') or Oncus (Ancient Greek: Ὄγκος, romanizedÓnkos, lit.'point of an arrow')[1] was a son of Apollo and a ruler over Ónkeion (Ὄγκειον), a region of Arcadia adjacent to Thelpusa,[2][3] as well as eponym of a city Oncae.[4] He owned a herd of horses, in which Demeter tried to hide from Poseidon's advances, changing herself into a mare. Poseidon did mate with her in the shape of a stallion, which resulted in the birth of the fantastic horse Arion. Oncius kept Arion and later gave him away to Heracles as the latter was starting a military campaign against Elis.[5]
