Celtic polytheism was one of a larger group of Iron Age polytheistic religions of the Indo-European family.

Sources

We know comparatively little about Celtic polytheism because the evidence for it is fragmentary, largely due to the fact that the Celts who practiced it wrote nothing down about their religion. Therefore all we have to study their religion from is the literature from the early Christian period, commentaries from classical Greek and Roman scholars, and archaeological evidence. The archaeologist Barry Cunliffe
Barry Cunliffe
Sir Barrington Windsor Cunliffe, CBE, known professionally as Barry Cunliffe is a former Professor of European Archaeology at the University of Oxford, a position held from 1972 to 2007...

 summarised the sources for Celtic religion as "fertile chaos", borrowing the term from the Irish scholar Proinsias MacCana. Cunliffe went on to note that "there is more, varied, evidence for Celtic religion than for any other example of Celtic life. The only problem is to assemble it in a systematic form which does not too greatly oversimplify the intricate texture of its detail."

Greek and Roman records

Various Greek and Roman writers of the ancient world commented on the Celts and their beliefs. Barry Cunliffe stated that "the Greek and Roman texts provide a number of pertinent observations, but these are at best anecdotal, offered largely as a colourful background by writers whose prime intention was to communicate other messages."

The evidence from Ireland has been recognised as better than that from Wales, being viewed as "both older and less contaminated from foreign material." These sources, which are in the form of epic poems and tales, were written several centuries after Christianity became the dominant religion in these regions, and were written down by Christian monks, "who may not merely have been hostile to the earlier paganism but actually ignorant of it."

. Because they were written in a very Christian context, these sources must be scrutinised with even more rigor than the classical sources in assessing their validity as evidence for Celtic religion.

 terms, as other "pagan" peoples such as the Greeks, Romans, and Egyptians did. This appeared to change as the classical peoples grew in influence over the Celtic cultures, as the Celts did begin to give their deities human forms, and they moved from a more animistic-based faith to a more Romanised polytheistic view.

Several of these deities, including Lugus and Matrones, exhibited triplism, being found in a set of three.

Insular mythology

 is."

Examining these Irish myths, Barry Cunliffe stated that he believed they displayed "a dualism between the male tribal god and the female deity of the land" whilst Anne Ross felt that they displayed that the gods were "on the whole intellectual, deeply versed in the native learning, poets and prophets, story-tellers and craftsmen, magicians, healers, warriors… in short, equipped with every quality admired and desired by the Celtic peoples themselves."

Insular Celts swore their oaths by their tribal gods, and the land, sea and sky; as in, "I swear by the gods by whom my people swear" and "If I break my oath, may the land open to swallow me, the sea rise to drown me, and the sky fall upon me."

Cultic practice

Evidence suggests that amongst the Celts, "offerings to the gods were made throughout the landscape – both the natural and the domestic." At times they worshipped in constructed temples and shrines, evidence for which have been unearthed across the Celtic world by archaeologists, although according to Greco-Roman accounts, they also worshipped in areas of the natural world that were held to be sacred, namely in grove

Votive offerings

The Celts produced votive offerings to their deities, which were buried in the earth or thrown into rivers or bogs. According to Barry Cunliffe, in most cases, deposits were placed in the same places on numerous occasions, indicating continual usage "over a period of time, perhaps on a seasonal basis or when a particular event, past or pending, demanded a propitiatory response."

In particular, there was a trend to offer items associated with warfare in watery areas, evidence for which is found not only in the Celtic regions, but also in Late Bronze Age (and therefore pre-Celtic) societies and those outside of the Celtic area, namely Denmark. One of the most notable examples is the river Thames in southern England, where a number of items had been deposited, only to be discovered by archaeologists millennia later.
