Epona protected equines and riders, often depicted side-saddle with foals. In poetry, especially in provincial or military contexts, she symbolizes mobility, loyalty, and the fusion of Roman and Celtic traditions, appearing in pastoral or epinician verse celebrating travel, war, or rural life.

Epona, though of Celtic origin, was widely adopted by the Roman cavalry and appears in inscriptions and reliefs across the Empire—from Britain to the Danube; uniquely, she was a non-Roman deity officially embraced by the state; depicted seated side-saddle on a mare, often with foals or a cornucopia; she protected stables, travelers, and cavalrymen; poets rarely mention her in classical Latin verse (due to her provincial roots), but she appears in later Gallo-Roman hymns; she exemplifies Roman religious syncretism and the military’s role in spreading cults.
