Fans of Asterix will instantly recognize the recurring cries of “By Toutatis!”, “By Belenos!” or “By Belisama!” — often shouted in moments of shock, frustration, or triumph by the indomitable Gauls. But who were these deities, and what do we really know about them from history? Far from mere comic exclamations, they were actual gods worshipped by Celtic tribes across Europe, long before the arrival of Roman rule. Here is a factual look at the origins and historical significance of these two ancient deities.
Toutatis: Protector of the Tribe
The name Toutatis (also spelled Teutates) appears in Roman accounts of Celtic religion, most notably in the writings of Lucan, a Roman poet of the 1st century CE. In his epic poem Pharsalia (Book I, line 444), Lucan refers to three main Celtic deities: Teutates, Esus, and Taranis.
The name Toutatis derives from the Gaulish word touta, meaning “tribe” or “people,” and Toutatis can be translated as “god of the tribe” or “guardian of the people.” This suggests a protective role—he was likely a tribal patron deity invoked for safety, unity, and success in battle.
Toutatis was possibly associated with Mars or Mercury by the Romans, who often equated local gods with their own pantheon. Rituals dedicated to him were thought to involve offerings made in sacred groves, sometimes with grim overtones, though historical accuracy on this point is debated.
Belenos: God of Light and Healing
Belenos (also spelled Belinus) was another important deity in the Celtic pantheon, widely worshipped from Gaul to northern Italy and even in Roman Britain. His name is often interpreted as meaning “shining one” or “bright one,” linking him to the sun and healing.
He was associated by the Romans with Apollo, the Greco-Roman god of healing, music, and sunlight. Inscriptions dedicated to Belenos have been found across the Celtic world, particularly in Aquileia in northern Italy, a major center of his cult.
Belenos was likely celebrated during the Beltaine festival (May 1st), which marked the beginning of summer in the Celtic calendar. The festival was known for its fires, symbolizing purification, fertility, and renewal—concepts closely tied to a solar deity.
Belisama: The Bright Goddess of Fire and Craft
Belisama was a Celtic goddess venerated primarily in Gaul and Britain, often associated with light, fire, craftsmanship, and possibly wisdom. Her name is thought to mean “the most brilliant one” or “very bright,” sharing a root with Belenos, which suggests a possible divine pairing or complementary function. The Romans equated Belisama with Minerva, the goddess of wisdom, strategy, and the arts, indicating that Belisama may have been revered not only as a solar or fiery figure but also as a patroness of skilled labor and learning. Inscriptions dedicated to her have been found in regions such as Saint-Lizier in southern France, where she was honored with the Latin epithet augusta, signaling official imperial recognition. Though less widely known than Belenos or Toutatis, Belisama reflects the regional diversity and richness of Celtic spirituality, in which deities of light often had overlapping and localized identities.
Their Role in the Asterix Comics
In the Asterix series, both gods appear as humorous expletives rather than active divine figures. “By Toutatis!” is the most often used catchphrase, while “By Belenos!” is used occasionally as well. Belisama’s name is uttered even less often. While these oaths are played for laughs, they reflect a clever use of real Celtic cultural elements, grounding the comic’s humor in historical texture.
The creators, René Goscinny and Albert Uderzo, often drew from authentic Gallic names, customs, and places to enrich the world of Asterix. Using Toutatis and Belenos not only added flavor to the language of the characters but also paid homage to the rich and largely forgotten spiritual world of the ancient Celts.
Conclusion: Ancient Gods in a Modern Comic World
Though Asterix uses Gaulish gods for comic effect, these gods were deeply rooted in the religious life of Iron Age Europe. Toutatis, the tribal guardian, Belenos, the radiant healer, and Belisama the god of fire were part of a complex and regionalized pantheon that played a major role in pre-Roman culture. Their echoes survive not just in inscriptions and historical records—but also in the spirited oaths of a small village in Armorica that still holds out against the Romans.
