Tarrennus

Tarrennus is a figure from Gallic mythology, primarily known through Roman sources. He is considered a Celtic deity worshipped by the Gaulish tribes. His name is often associated with the god Mars, as evidenced by interpretatio romana, a practice where Roman gods were identified with foreign deities that shared similar characteristics. Inscriptions found in Gaul, particularly in the region of the Treveri people, link Tarrennus to warlike attributes and protection.

His worship appears to have been concentrated in northeastern Gaul. While specific details of his myths and cult practices are scarce, the association with Mars suggests he was a god of war, fertility, and perhaps sovereignty. Offerings and dedications to Tarrennus often indicate a connection to military success and the well-being of the community. The archaeological evidence, primarily votive offerings and inscriptions, provides the most significant insights into his role within the Gallic pantheon. The exact etymology of his name remains debated among scholars, but it is generally believed to have Celtic roots.
