In Gallo-Roman religion, Epona was a goddess associated with horses and ponies. She was also linked to fertility and motherhood. Art and sculptures often showed her holding a patera, cornucopia, ears of grain, and foals. Some stories suggest she and her horses guided souls to the afterlife, similar to the character Rhiannon in the Welsh Mabinogion.
Epona was widely honored as the protector of soldiers who rode horses throughout the Roman Empire from the 1st to the 3rd centuries AD. Unlike other Celtic gods and goddesses, who were usually tied to specific places, Epona was the only Celtic deity worshipped in the city of Rome itself.
Etymology
The name Epona, meaning "Great Mare," comes from Gaulish, an ancient Celtic language that no longer exists. It is believed to be based on the Proto-Indo-European word for horse, éḱwos, which later appeared in Proto-Celtic as ekʷos ("horse") and became the Celtic word *epos ("horse"). The name Epona includes the suffix -on, which is often used in the names of gods or goddesses (such as Sirona and Matrona) and also appears in Gaulish feminine singular forms ending with -a. Some scholars also suggest that the suffix -ona (or -ana) might refer to sacred water, such as springs or other water sources.
Origins
One of the earliest records of Epona as a goddess appears in the Satires (100–127 CE) by Juvenal, which connects her worship and symbols to stables. Small images of Epona have been discovered in Roman stables and barns across many regions. She is also mentioned in The Golden Ass (2nd century CE) by Apuleius, which describes a small room in a stable containing a pillar with Epona’s image, decorated with fresh roses.
A story explaining Epona’s origin is found in Parallela Minora, a text believed to be written by Pseudo-Plutarch. It says that Fulvius Stellus disliked women and lived with a mare. The mare gave birth to a girl named Epona, who became a goddess associated with protecting horses. This story is mentioned by Agesilaüs in his Italian History.
This tale was later included in Giambattista Della Porta’s Magia naturalis (1589), though it incorrectly attributed the story to Plutarch’s Life of Solon. The story may reflect ancient traditions involving horse sacrifices, such as the Vedic ashvamedha ritual or an Irish ceremony described by Giraldus Cambrensis. These rituals were linked to kingship. In Celtic traditions, a king would mate with a white mare believed to represent the goddess of sovereignty.
Pausanias also wrote about a similar Greek myth involving Demeter Erinys, known as "Vengeful Demeter." In the story, Demeter, in the form of a mare, was attacked by Poseidon, who appeared as a stallion. Demeter was honored as a mare in Lycosoura, Arcadia.
Functions and worship
Most artifacts connected to Epona have been discovered in areas that were once part of eastern and northeastern Roman Gaul and near the Roman limes in the German Rhineland, regions where cavalry units were stationed. Historian Fernand Benoît suggested that the earliest worship of Epona began in the Roman Danubian provinces and that she was brought to the Gallic limes by horsemen from the east. However, this idea is not widely supported by other scholars. Evidence of Epona’s worship includes votive objects, inscriptions, and small statues made of stone or clay. These items are often found near sacred water sources, such as wells, springs, and the Moselle River, suggesting that Epona was believed to have healing powers.
Although the name "Epona" is Gaulish, most dedicatory inscriptions to her are written in Latin or, less often, in Greek. These inscriptions were created by people of various backgrounds, including Celts, Germans, and others living in the Roman Empire. One inscription from Mainz, Germany, was made by someone from Syria. Most inscriptions were created by individuals, often non-officers in the military—particularly cavalry members—with Romanized names.
A Latin inscription from the first century BCE, found on a lead sheet in Rom, Deux-Sèvres (a Roman settlement called Rauranum), was discovered in 1887. It accompanied the sacrifice of a young female horse and the offering of a cauldron. The inscription includes many names for Epona, such as Eponina, Atanta, Potia, Dibonia, Catona, and Vovesia. However, this interpretation is not widely accepted. Another scholar, Meid, believes the inscription refers to the goddess Dibona and was used to seek help in a personal matter.
Two inscriptions mention a temple dedicated to Epona in modern-day Nièvre, France. This temple was likely built on the site where the Gallic leader Vercingetorix was defeated by Julius Caesar in 52 CE. Evidence of possible religious sites has also been found in Asse and Elewijt, modern-day Belgium.
In Roman-occupied Gaul, Epona was worshipped as a mother goddess who protected horses, donkeys, mules, and their riders. Horses were important in Gallic life, as seen when Vercingetorix sent his horses away to avoid their capture. Epona may have represented fertility, abundance, and protection, as altars dedicated to her were often placed in stables. Though later linked to the cavalry, early images of Epona suggest she was a peaceful goddess associated with fertility and safety, not war.
Some objects dedicated to Epona suggest she had a role in funerary practices. In some cultures, horses were believed to guide souls to the afterlife. Benoît noted that images of Epona and a serpent-tailed figure may symbolize overcoming death, a theme that spread to Gaul through contact with Etruria and Magna Graecia.
When Romans encountered Celtic gods, they often compared them to Roman deities through a process called interpretatio romana. As Gaul became more Roman, Epona’s role shifted to protecting cavalry units. Local traditions and her worship spread across the empire through military groups like the auxilia, alae, numeri, and equites singulares, which were mostly recruited from Gaul, Lower Germany, and Pannonia. Because few offerings or inscriptions remain, scholars believe Epona may have kept her connection to healing and fertility even after being adopted by the Romans.
Epona’s feast day was recorded as December 18 on a rustic calendar from Guidizzolo, Italy, though this may have been a local tradition. She was later included in the Roman imperial cult and honored as Epona Augusta or Epona Regina ("queen").
Evidence of Epona’s worship has been found as far west as the Roman province of Hispania, in the Iberian Peninsula. Her worship was likely centered in Celtiberia, a region with Hispano-Celtic speakers that later became part of the Roman Empire. She was known as Epane in modern-day Spain’s Cantabria and Palencia regions. In art from this area, Epona is often shown riding a horse, standing among horses, or feeding foals.
A small stone altar dedicated to Epona was found in Andújar, Andalusia, and dates to the late first or early second century CE. The goddess is not shown on the altar, but a mule is carved into the surface. The spread of Epona’s worship beyond Celtiberia to cities near the Sierra Morena mountains may be linked to the region’s copper mines, where her followers likely worked or owned mines.
In Britain
A small Roman bronze statue of a seated Epona, about 7.5 cm tall, was discovered in England. Next to her are a very small mare and stallion. On her lap and on the patera in her right hand are ears of grain that are much larger than normal. Ears of grain also come out of the mouths of the ponies, whose heads face the goddess. In her left hand, she holds a yoke that curves over her shoulder. This feature is unique to this bronze statue.
In the West Country, specifically in Padstow and Minehead, the tradition of May Day hobby-horse parades continued until the 20th century. At the end of the celebrations in Padstow, the hobby-horse was once ritually placed in the sea. Some experts believe this festival may have roots in the worship of Epona. However, there is no clear evidence that the festival existed before the 18th century. A southern Welsh tradition called Mari Lwyd (Grey Mare) is still practiced in December. Some experts also suggest this event may have connections to Epona. However, there is no clear evidence to support this idea.
In the medieval Welsh collection of stories called the Mabinogion, the royal figure Rhiannon rides a white horse that moves so smoothly and quickly that it cannot be caught. She is wrongly accused of killing her child and must live as a horse for seven years as punishment. During this time, she offers to carry travelers to the court and tells them her story. She also wears the collar of an ass. Rhiannon and her son, who is fathered by a sea god (similar to the Romano-Greek god Poseidon, who rules over horses and the sea), are sometimes described as a mare and foal. Ronald Hutton is unsure about claims that connect Epona and Rhiannon. He believes Rhiannon is a much later character from stories, even though she may have been influenced by older oral traditions that are now lost.
Iconography
Sculptures of Epona are classified into five types by Benoît: riding, standing or seated before a horse, standing or seated between two horses, a horse tamer in the style of potnia theron, and a symbolic mare with a foal. Most statues are made of stone, bronze, or terracotta and often show the goddess riding with both legs on one side of a horse. In the Equestrian type, common in Gaul, she is shown sitting side-saddle on a horse or, less often, lying on one. In the Imperial type, more common outside Gaul, she sits on a throne surrounded by two or more horses or foals.
Epona is frequently depicted holding a cornucopia, a symbol of abundance, along with bowls or dishes containing fruit, bread, or grain. These items may have been added by the Romans. Similar objects are also associated with other goddesses of fertility, such as Fortuna and the Matres. She is sometimes shown with birds or dogs, the latter being a symbol of Sucellus, a Gallic god of agriculture and wine.
Reliefs and sculptures of Epona have been found in Pannonia, Moesia Inferior, Dacia, and the central Balkans. She is often shown seated, flanked by two horses, wearing a long-sleeved tunic (chiton) with a belt and a himation draped over it. She also appears on the handle of a silver patera, holding a foal and wearing a corona muralis. Her worshippers in this region were likely blacksmiths and miners from Gaul who worked in local silver and lead mines. Additionally, Epona may be the unidentified goddess shown interacting with the Thracian Horseman, a mysterious deity worshipped in the area.
In literature and art
In The Legend of Zelda video game series, the main character Link has a horse named Epona. Epona is always shown as a palomino or light brown horse with a white mane. In 1987, musician Enya released an album that includes a song titled "Epona." This song was part of the soundtrack for the BBC documentary The Celts.
Today
On Mackinac Island, Michigan, Epona is honored each June with activities such as stable tours, a blessing of animals, and the Epona and Barkus Parade. Mackinac Island does not allow personal cars; horses are the main way to travel there, making the celebration of Epona especially meaningful in this area of the upper Midwest. The "Feast of Epona" includes a blessing of horses and other animals performed by a local church leader.
Epona is also worshiped today by neo-druids and others who follow pagan or polytheist beliefs.
The name Epona inspired the name of the EPONA (Energetic Particle Onset Admonitor) instrument on the Giotto spacecraft.
