Celtiberian and Continental Celtic Paganism: The Forgotten Branches

When most people think of Celtic paganism, they think of Ireland, Wales, or Scotland. The Atlantic fringe. The sea cliffs and misty hills that have become the visual shorthand for all things Celtic.

But the Celtic-speaking world was enormous, and its eastern and southern extensions produced traditions that are genuinely part of the Celtic family while being almost entirely absent from popular pagan conversation. This page covers those traditions: the Celtiberians of the Iberian Peninsula, the continental Celtic peoples of central Europe, and the Galatians of modern-day Turkey.

These are among the most fragmentary branches of Celtic paganism. They are also among the most interesting precisely because of that fragmentation, and because the practitioners who work with them are doing genuinely careful reconstructive work with minimal romanticization to fall back on.

Who Were the Continental and Celtiberian Celts?

The Celtic languages and cultures that most people associate with the British Isles originated in continental Europe. The La Tène culture of the Iron Age, centered in what is now Switzerland, France, and southern Germany, is the archaeological tradition most closely associated with the spread of Celtic language and culture across Europe.

From this central zone, Celtic-speaking peoples expanded in multiple directions: westward into Gaul and ultimately Britain and Ireland, southward into the Iberian Peninsula, and eastward through the Balkans and into Asia Minor.

The Celtiberians

The Celtiberians were Celtic-speaking peoples who inhabited a large part of the central and northeastern Iberian Peninsula from roughly the 6th century BCE onward. Their territory centered on the Meseta, the high plateau of modern Spain, and they developed a distinct culture that blended Celtic linguistic and artistic traditions with pre-existing Iberian cultural elements.

The Romans encountered the Celtiberians during their conquest of the Iberian Peninsula, and the Celtiberian Wars of the 2nd century BCE were some of the most brutal conflicts in Roman expansion. The siege of Numantia (133 BCE), where the Celtiberian defenders chose collective death over surrender, became legendary in antiquity.

The Celtiberian language is attested in a number of inscriptions written in an adapted Iberian script. These inscriptions, while limited, are genuine Celtiberian-language sources that supplement the Latin and Greek accounts.

The Galatians

In 279 BCE, a group of Celtic warriors migrated into the Balkans and eventually crossed into Asia Minor (modern Turkey), where they settled in the region that became known as Galatia, centered roughly on what is now Ankara. The Galatians maintained their Celtic language for several centuries and were recognized in antiquity as a Celtic people.

The Galatians are mentioned in the New Testament, which gives them an unusual degree of name recognition relative to their impact on modern pagan practice. Paul's Letter to the Galatians was written to a Celtic-speaking community.

Archaeological evidence from Galatia and accounts from Hellenistic authors provide some information about Galatian culture and religion, though this remains one of the most fragmentary areas of Celtic studies.

Other Continental Celtic Traditions

Beyond Gaul (covered in the Gaulish Polytheism page), Celtic-speaking peoples occupied significant portions of central Europe, including the area of modern Austria, southern Germany, and the Czech Republic. The Boii, the Scordisci, the Norici, and other peoples left archaeological evidence and occasional epigraphic material.

These central European Celtic traditions have received less attention from modern reconstructionists than Gaul or the British Isles, but they represent the heartland from which Celtic culture spread.

What the Sources Contain

Epigraphy

The most reliable evidence for Celtiberian religion comes from inscriptions. Votive dedications in the Celtiberian language, personal names with divine elements, and place names all contribute to an emerging picture of Celtiberian religious life.

Latin inscriptions from the Roman period in the Iberian Peninsula record dozens of deity names, many of them local or regional figures worshipped at specific sites. Some of these deities can be tentatively identified as Celtiberian or at least Celtic in origin.

Classical Sources

Roman and Greek writers provide accounts of the peoples of the Iberian Peninsula, including religious practices. Strabo's Geography contains descriptions of religious customs among Iberian peoples, some of which are relevant to Celtic groups. These accounts are fragmentary and filtered through Greco-Roman perspectives.

Archaeology

The material culture of the Celtiberian world is rich: distinctive warrior culture equipment, sanctuary sites, votive deposits, and urban settlements (oppida) have been excavated across central Spain. Several sites of clear religious significance have been identified, though their specific cultic content is often unclear.

The sanctuary at Ulaca in Ávila province, for example, includes a rock-cut altar platform that is among the most dramatic surviving Celtic ritual sites anywhere in Europe.

Celtiberian Deities

Lugus

The most widely attested pan-Celtic deity in the Iberian Peninsula is Lugus, and his presence here reinforces the picture of him as a deity worshipped across virtually the entire Celtic world. Inscriptions to the Lugoves (a plural form, possibly a triad) have been found at Uxama in Soria, and the city name Lugudunum (Lyon's Iberian cognate) suggests widespread cult.

As elsewhere in the Celtic world, Lugus in the Iberian context appears to be connected with skill, trade routes, and possibly kingship, though the specific character of his Iberian cult is less documented than his Irish or Gaulish manifestations.

Endovelicus

Endovelicus is one of the most interesting deities attested in the Iberian Peninsula, with over 80 inscriptions, making him one of the most epigraphically rich Celtic or Celtic-adjacent deities in the region. His sanctuary at São Miguel da Mota in what is now Portugal was a major healing and oracular site.

Whether Endovelicus was a Celtiberian deity or belonged to a pre-Celtic Iberian tradition that was later incorporated into the Romanized religious landscape is debated. His cult shows characteristics of healing, prophecy, and possibly a chthonic (underworld) dimension.

Ataecina

Ataecina was a goddess widely venerated in western Iberia, particularly in the region that is now Portugal and western Spain. She was associated with the underworld and with spring vegetation, a combination that suggests a death-and-renewal cycle in her mythology. Her name may derive from a Celtic root meaning "the eternal one" or "reborn."

She was frequently equated with the Roman goddess Proserpina, and her cult at Turobriga was important enough to survive well into the Roman period.

Epona

Epona's veneration extended into the Iberian Peninsula along with the Roman military, and she had pre-Roman connections to the Celtic populations of Iberia as well. The horse goddess, as elsewhere, carried associations of journey, sovereignty, and the passage between worlds.

Regional and Tribal Deities

Like Gaul, the Iberian Celtic world was populated with regional and tribal deities whose cults were local and specific. Bandua appears repeatedly in western Iberian inscriptions, possibly a deity of communal protection similar to the Gaulish Toutatis. Nabia is a goddess associated with rivers and valleys, attested in multiple inscriptions.

The sheer number of local divine names in the Iberian epigraphic record suggests the same pattern seen across the Celtic world: a landscape filled with specific divine presences, each connected to particular places, peoples, or functions, alongside more widely recognized pan-Celtic figures.

Galatian Religion

The Galatians of Asia Minor present a fascinating case study in Celtic religious adaptation. Living in a predominantly Hellenistic world, surrounded by Greek and Anatolian religious traditions, the Galatians maintained their Celtic identity while inevitably absorbing external influences.

Classical sources describe the Galatians as a distinctive people, recognizably Celtic in language and many cultural practices, including a warrior aristocracy and a priestly class. Their tribal divisions, the Trocmi, Tolistobogii, and Tectosages, corresponded to specific territories, and each tribe had its own sacred center.

The sacred site of Drunemeton (the "oak sanctuary" or "great nemeton") served as the political and presumably religious meeting place for the Galatian confederation. The name itself preserves the Celtic concept of the sacred grove.

Beyond this, Galatian religious practice is poorly documented. The pressures of Hellenistic and later Roman culture, followed by Christianization, left little specific evidence of Galatian religious content. What we know suggests a Celtic religious framework adapted to a very different landscape and cultural context.

The Central European Heartland

The Celtic cultures of central Europe, the La Tène heartland, have left an extraordinary material record even though the textual evidence is largely mediated through Roman sources.

The chariot burials, the elaborately decorated metalwork, the oppida with their sophisticated social organization, and the ritual deposits found across the Alpine region and central European river systems all point to a rich religious life. The Gundestrup Cauldron, found in Denmark but almost certainly manufactured in southeastern Europe or the Balkans by Celtic craftspeople, is one of the most important ritual objects in the Celtic world.

Central European Celtic sanctuaries (Viereckschanzen, rectangular enclosures with ritual shafts) have been excavated at numerous sites in southern Germany, Austria, and the Czech Republic. The deposits in these shafts, organic material, animal remains, and sometimes human remains, are evidence of a consistent ritual practice across a wide geographic area.

The Celtic peoples of central Europe were progressively absorbed into the Roman Empire in the west and displaced by Germanic migrations in the east over the final centuries BCE and early centuries CE. Their specific religious traditions did not survive intact, but the material record they left is a genuine resource for reconstructive work.

Why These Traditions Matter

The Celtiberian and continental Celtic traditions matter for several reasons beyond their intrinsic interest.

They expand the picture of Celtic religion. A Celtic paganism that focuses only on Ireland, Wales, and Scotland is working with a partial picture. The full Celtic world was geographically vast and culturally diverse. Including the Iberian and continental branches gives a more accurate understanding of how pan-Celtic religious concepts like Lugus, the nemeton, the Druids, and sacred water sites appeared consistently across a huge area.

They demonstrate adaptation. Celtic peoples adapted their religious traditions to radically different landscapes and cultural contexts, from the Atlantic coast to the Anatolian plateau. This flexibility and adaptability is itself an important feature of Celtic religious life, not a corruption of some pure original form.

They offer a genuinely reconstructive practice. Because the source material is so sparse, practitioners working with Celtiberian or Galatian traditions cannot fall back on a ready-made mythological framework. They have to build their practice carefully from what the evidence actually supports, which produces a distinctively rigorous and honest approach.

Modern Practice in These Traditions

Modern practitioners of Celtiberian or continental Celtic paganism are a small community doing serious work. Organizations and individuals focused on Celtiberian reconstructionism have developed frameworks for practice based on the epigraphic and archaeological record, often in dialogue with broader Celtic polytheist communities.

Core elements of modern Celtiberian practice typically include:

Deity veneration based on the epigraphic record. Working with the attested deities, Lugus, Ataecina, Endovelicus, Bandua, and others, using the inscriptions as primary evidence for how they were honored.

Landscape engagement. The Iberian plateau, the river valleys, the mountain sanctuaries like Ulaca. Even practitioners living outside Iberia engage with the tradition's strong sense of sacred landscape.

Reconstructive rigor. The absence of mythology forces a different approach. Practice is built from the ground up using archaeological and epigraphic evidence, comparative Celtic material, and direct spiritual engagement.

Community and scholarship. The Celtiberian reconstructionist community maintains close ties with academic Celtic studies in Spain and Portugal, and the quality of scholarly engagement in this tradition is generally high.

Getting Deeper

The academic literature on Celtiberian religion is primarily in Spanish, Portuguese, French, and German, which presents a barrier for English-speaking practitioners. The best English-language starting points are:

• Barry Cunliffe's By Steppe, Desert, and Ocean for the wider picture of Celtic expansion
• Academic papers on Iberian epigraphy available through JSTOR and university repositories
• The Hispania Epigraphica database for inscriptions from the Iberian Peninsula
• John Koch's Celtic Culture encyclopedia for broad reference

The communities working with these traditions online, particularly in Spain and among the Celtic polytheist diaspora, are producing thoughtful reconstructive work worth seeking out.

These are not traditions for people who want ready-made mythology and simple entry points. They are for people who want to work seriously with what the evidence actually says, and who find that rigor spiritually meaningful rather than limiting.

If that's you, this corner of the Celtic world has been waiting.
