Celtic Religion: Druids, Gods and the Sacred Grove

Celtic religion was the belief of the Celtic peoples of central and western Europe – from Gaul via Britain into the Alps. As with the Germanic peoples, their own written sources are almost entirely lacking; we depend on Caesar, other ancient authors and archaeology. And as with the Germanic peoples: it was no uniform dogma, but regionally varied belief.

The Druids

The best-known figures are the Druids – priests, judges and scholars in one. Caesar describes them as a powerful elite class that watched over law and cult, learned by heart for years (nothing might be written down) and led sacrifices. Their knowledge they passed on orally – which is why we barely know it.

The gods

The Celtic world of gods was large and regionally varied. Well known are Lugh (light/craft), Taranis (thunder, with a wheel symbol), Teutates ("god of the tribe", from toutā = people) and Cernunnos, the antlered "lord of the animals" – famous from the silver cauldron of Gundestrup. Caesar simply assigned them to Roman gods: Mercury, Apollo, Mars, Jupiter, Minerva.

Parallels to Germanic belief

The closeness to Germanic belief is striking: sacred groves (Celtic nemeton) instead of temples, worship at springs and in forests, a war god of the Mars type. Especially fine is the linguistic bridge: Celtic Teutates (from toutā, "people") and Germanic *þeudō ("people", cf. German "deutsch") go back to the same Indo-European root – a "god of the people" on both sides of the Rhine. The Rhine was, after all, a border of the Romans, not a wall between two utterly foreign worlds.

Celtic religion is the great neighbour of the Germanic – related in grove, wealth of gods and sense of the world. More on the Roman renaming of Germanic gods in the article Interpretatio Romana.
