Frequently asked questions

Epona is a Gaulish goddess who protects horses, mares, foals, donkeys and mules. The key thing to remember is that she is the only Celtic deity to have been officially incorporated into the Roman calendar, with a festival on 18 December. Her name comes from the Gaulish epos (“horse”), making her literally “the divine horsewoman” or “the great mare.” Unlike other Celtic figures, Epona is not a warrior goddess: she embodies fertility, abundance and the protection of mounts, which explains her immense popularity among riders and breeders.

Anecdotes

Epona is the only Gaulish deity to have been honored with an official public holiday in the Roman calendar: December 18 was dedicated to her, as attested by a rustic calendar found at Guidizzolo, in Italy. No other Celtic deity received such an honor in the Roman world.

Hundreds of depictions of Epona have been found throughout the Roman Empire, from Britain to the Balkans: she is by far the deity of Gaulish origin best attested by archaeology. Most show her seated sidesaddle on a mare, or surrounded by horses.

Roman cavalry soldiers, many of whom were recruited in Gaul, venerated Epona so that she would protect their mounts. Altars and statuettes were dedicated to her in the stables of military camps, sometimes adorned with fresh roses.

Epona appears in a Latin novel, the *Metamorphoses* (or *The Golden Ass*) by Apuleius in the 2nd century: the hero describes a small statue of the goddess placed in a stable niche, decorated with garlands of roses. It is one of the few literary mentions of her cult.

Her name comes from the Gaulish word *epos, meaning “horse,” related to the Latin equus and the Greek hippos. Epona thus literally means “the great mare” or “the divine horsewoman.”

Primary Sources

Apuleius, Metamorphoses (The Golden Ass), Book III (c. 160-170 AD)
In a niche carved right in the middle of the posts that supported the stable's roof beams, one could see an image of Epona, reverently adorned with garlands of freshly bloomed roses.
