Gallo-Roman religion
In the province of Gaul, a woman named Rosmerta stood beside Mercury. This pairing appeared on stone altars and bronze statues across the region. Roman gods took on local names like Lenus Mars or Jupiter Poeninus. These epithets merged distinct identities into single figures worshipped by the people. A native Celtic goddess named Epona received worship from Romans as well. She was an equine deity who protected horses and travelers. Mother goddesses retained their importance throughout Gallo-Roman society. Epigraphic evidence suggests a triad of mother goddesses held particular significance in daily life. The water deity Sulis merged so completely with Minerva that the terms became interchangeable. People prayed to Sulis Minerva at hot springs believed to have healing properties near Aquae Sulis. One offering found near Auxerre depicted Minerva next to a Gallic goddess possibly named Ritona. Healing deities such as Glanis and the Glanicae were also merged with Valetudo. Cobannus may have been worshipped with Romanized practices in temples associated with local theatres. His name appears alongside Roman gods in inscriptions found throughout the region.
Eastern mystery religions penetrated Gaul early during the first century CE. Followers gathered for cults dedicated to Orpheus, Mithras, Cybele, and Isis. The imperial cult centered primarily on the numen of Augustus gained prominence in public religion. This worship reached its peak at the Sanctuary of the Three Gauls located at Lugdunum. Emperor Augustus banned the druids, an important priestly class in pre-Roman Gaul. Tiberius continued these policies by outlawing vates and healers. Local elites sought to maintain their position within the new social hierarchy. They adopted more Roman styles of religious leadership to demonstrate their newfound Romanitas. Latin became the standard language of Gallo-Roman religion. Drusus established a cult center near Lyon where local magistrates supervised functions. The Roman government provided formal structures for the emerging religion to operate within. These changes diminished the importance of religious sites associated with vanished social hierarchies. Expressions of Romanized culture aided this process by showing identity as Romans. Many votive dedications to Sulis Minerva have been found located near springs throughout Gaul.
A characteristic Gallo-Roman temple or fanum is identifiable from its concentric shape. Celtic religious views on water likely influenced Gallo-Roman temple design. Many temples are located nearby sources of water stemming from the importance of water in Celtic religion. Gallo-Roman temples were often quadrangular usually square-shaped less commonly rectangular. Sometimes they were circular or polygonal though this occurred infrequently. Construction used imperishable materials such as tiles or stone featuring painted wall plaster or columns. Some examples featured an externally polygonal but internally circular cella or a hexagonal cella. Twin temples surrounded by an ambulatory gallery existed as rare exceptions. Unlike Classical Roman temples, entrances typically oriented eastward due to topographic issues preventing other directions. This practice may have connected to circambulation rituals. Earlier Celtic religion had less emphasis on structured monuments and temples. The temple at Gournay-Sur-Aronde was once a pre-Roman Celtic site consisting of nine free-standing posts enclosing a central ditch. After Romanization it was rebuilt around a central cella with cob walls on a stone foundation. It retained the original layout while changing building materials to resemble Roman architecture. By the 1st century CE Gallo-Roman styles had been largely replaced by Classical architecture.
Gallo-Roman inscriptions detailing private offerings appear far more frequently than public votive offerings from priests. Public dedications from military officers or magistrates are much rarer in Gaul than elsewhere in the empire. Most votive inscriptions were recorded using inscribed metal plates announcing vows or monuments commemorating dedication. Altar stones including sacrificial altars were among the most common types of votive monuments in northwestern provinces. These altars contained iconography depicting ritual sacrifices or equipment used during ceremonies. Physical representations displayed publicly in sanctuaries highlighted the social status of the individual responsible. Altars from the Rhineland typically made from local varieties of sandstone. Some were constructed from Northern French limestone which was more expensive and higher quality. Individuals who could afford the higher quality stone utilized their wealth to create permanent markers of piety. Weapons were used as votive offerings to war deities in pre-Roman Gaul. This practice possibly continued during Roman rule though weapon deposits have also been found in areas that did not practice the tradition before conquest. Such evidence indicates these offerings may not have been a direct continuation of Celtic traditions.
The Roman Emperor Claudius prohibited the practice of human sacrifice in Gaul. Roman policies may not have affected rates of human sacrifice since the practice may have already dissipated. These laws served as pro-Roman propaganda meant to illustrate moral and cultural superiority. Instead of human sacrifice, the population adopted similar Romanized substitutes. Pomponius Mela describes a Gallo-Roman practice where sacrificial victims had blood drawn as they led to the altar. Archaeological excavations in Belgic Gaul uncovered ruins of a man woman and child in an ancient well. These skeletons may have been part of a human sacrifice possibly to stimulate utility of the well. Celtic practices of animal sacrifice likely remained unchanged after the Roman conquest. The Romans likely did not end the practice of headhunting in Gaul as Strabo claims. One funerary stele from Kollmoor depicts a Roman auxiliary cavalryman stamping on the head of a defeated Suebian warrior. Another relief from Paris shows severed heads hanging from trees. A votive offering on a frieze from Arles depicts votive offerings of severed heads. It is possible that headhunting became more accepted within the Roman military due to influence of Gallic culture.
Pre-Roman Celtic depictions of deities mixed with Roman art styles to form unique Gallo-Roman art. Gallo-Roman depictions of Mercury often contain features resembling Celtic deities rather than standard Roman ones. One statue found near Lezoux depicts a bearded elderly Mercury dressed in tunic and breeches wearing petasos. He carried a purse and caduceus accompanied by a goat and rooster. Another statue near Néris portrays him holding a ram-headed serpent alongside a Gallic goddess possibly Rosmerta. Celtic depictions of Jupiter differ significantly from standard Roman counterparts. One bronze statuette from Haute-Marne depicts Jupiter holding thunderbolt in raised right hand and six-spoked wheel in left. Right shoulder suspended by nine bronze spirals representing symbols of god Taranis and other sky deities. Divine cons pairs of male and female deities are common theme originating from Celtic religion. These pairings symbolically represented union of Gallic and Roman religion legitimizing Roman deities by inserting them into pantheon. Mars Lenus paired with Ancamna while Mars Loucetius paired with Nemetona. By 1st century CE Romanized art styles had largely supplanted Gallo-Roman styles.
