Sources : Centaur
Isidore of Seville [7th century CE] (Etymologies, Book 11, 3:37; 12, 1.3): [Book 11, 3.37]Their [the chimera] appearance gave their name to the Centaurs, that is, a man combined with a horse. Some say that they were horsemen of Thessaly, but because, as they rushed into battle, the horses and men seemed to have one body, they maintained the fiction of the Centaurs. [Book 12, 1.43] ...in the Centaur the nature of horses and of humans is combined. - [Barney, Lewis, et. al. translation]
