A Celtic Goddess
Epona was a goddess of horses honored by the Celtic tribe known as the Gauls. Interestingly, she was one of the few Celtic deities who were celebrated by the Romans, and they celebrate her in an annual festival every December 18. The Festival of Epona was a time when worshipers paid tribute to horses, erecting shrines and altars in their stables, and sacrificing animals in Epona's name. Scholars say that the reason Epona was adopted by Romans was because of their military's love of the horse. Roman cavalry members honored her with temples of her own.

Legend holds that Epona was born to a white mare who was impregnated by a man who didn't much like women. According to Plutarch, Fulvius Stella "loathed the company of women," and so decided to focus his desire on the mare instead. Although this story of Epona's birth is the popular one, it is a very unusual beginning for a Celtic deity.

In many sculptures, Epona is represented by symbols of fertility and abundance, such as cornucopias, along with young foals. She is typically portrayed either riding, usually side-saddle, or taming a wild horse. Many households, particularly those who kept horses or donkeys, had statues of Epona on their household shrines. Epona is venerated in other areas; the Welsh Rhiannon is an adaptation of Epona's role as goddess of the horse.
