Babieca was the
war horse of the
Spanish military leader
El Cid in the
eleventh century. Several stories exist about the Cid and Babieca. Babieca, a
Spanish word for "simple," or "stupid," was said to be a white
Andalusian horse. In one story, Babieca is a gift from the Cid's godfather, a
Carthusian monk who gives him his pick of Andalusian horses as a coming-of-age present. According to legend, the Cid chose Babieca, a white horse who was frail and wild. This caused the Cid's godfather to exclaim "Babieca!" (stupid), which became his name. Another etymology suggests that the horse came from the Babia region in
León, Spain. Another explanation (mixture of the both previous) could be that in Spanish to say to somebody "You are in Babia" means that that person is not paying attention or being thoughtless.
