First-Ever Painted Depiction of Celtic God Sucellus Discovered at Gallo-Roman Sanctuary

Archaeologists excavating a hilltop sanctuary in eastern France have uncovered a remarkable painted altar block depicting Sucellus, a powerful Celtic deity associated with prosperity, forests, and agriculture. The discovery was made at the Gallo-Roman sanctuary of Mancey in Burgundy’s Saône-et-Loire region and may represent the only known painted depiction of the god ever found.

The sanctuary, located on a forested ridge overlooking the Tournugeois landscape near the town of Tournus, has been under systematic investigation since 2023. Excavations during the 2025 field season revealed a sprawling ritual complex that remained active for nearly five centuries, from the late Iron Age through the final centuries of the Roman Empire.

The painted altar block emerged from the ruins of a temple identified by archaeologists as Monument M3, where evidence suggests that ceremonial banquets and elite gatherings once took place. The temple floor contained thousands of remains from ritual feasts—including bones of pigs, birds, and fish—along with drinking vessels, jewelry, coins, and votive objects.

The Hammer-Bearing God of Prosperity

Sucellus was one of the most widely worshipped gods in Roman Gaul, often depicted carrying a long-handled hammer or mallet and accompanied by a wine jar or barrel, symbols linked to fertility, abundance, and protection of rural life. In inscriptions and sculptures found across Gaul, he sometimes appears alongside the goddess Nantosuelta, forming a divine pair connected with prosperity and the natural world.

Although dozens of stone sculptures of Sucellus are known from sites across France, Germany, and Luxembourg, painted representations of the god are extremely rare. If the identification of the Mancey altar is confirmed, it could provide a unique glimpse into the visual culture of Celtic religious worship during the Roman period.

Ritual Life on a Sacred Hill

Archaeologists believe the sanctuary covered roughly one hectare and included two temples, gathering areas, and spaces used for ritual meals and offerings. Thousands of artifacts recovered from the site suggest it attracted large numbers of visitors and may have served as an important regional cult center.

Even after the temples collapsed in the late fourth century AD, people continued to visit the sacred hill, leaving coins, figurines, and offerings among the ruins.
