[German version]

(Καινεύς; Kaineús, Lat. Caeneus). The name of a Lapith ruler, father of the Argonaut  Coronus. In early Greek mythology, this figure is clearly only connected to centauromachy. Because C. is invulnerable, the  Centaurs destroy him by ramming him into the earth with trees and stones (first recorded by Pind. fr. 167). His story is later elaborated on whereby C. was originally a girl (Lat. Caenis) who was raped by Poseidon and then requests that he change her into a man (schol. Apoll. Rhod. 1.57-64a; Ov. Met. 12.169-209; 459-535).
