Region

Period

c. 500 BC – 500 AD

The Celtic gods were worshipped by the peoples of Ireland, Britain, and Gaul, with the aid of the druids, their priestly caste. They venerated them in sacred groves, springs, and wells, without great stone temples. Many of their myths survived in the Irish and Welsh sagas, recorded by medieval monks.

The Celtic wheel of the year turned on four great fire festivals: Samhain, the origin of Halloween, opened winter and contact with the dead; Imbolc, Beltane, and Lughnasadh marked spring, summer, and the harvest. The druids led the rites in sacred groves called nemeton.

At a glance

Danu (frequently identified or associated in early medieval Gaelic literature with Anu or Ana) is the primordial mother goddess, patroness of earthly fertility, flowing rivers, and eponymous divine progenitor of the Tuatha Dé Danann ('The People of the Goddess Danu') in Irish Celtic mythology. Regarded as the cosmological and spiritual wellspring giving birth to the race of divine seers, healers, and warriors of ancient Ireland, Danu embodies the sovereign abundance of the earth and the life-giving currents of freshwater rivers. In the 10th-century etymological treatise Sanas Cormaic (Cormac's Glossary) compiled by King-Bishop Cormac mac Cuilennáin, the goddess Anu is explicitly glossed as mater deorum hibernensium ('mother of the Irish gods'), praised for the boundless nourishment with which she suckled and sustained the divine pantheon. The most enduring geographical monument to her worship stands in the twin hills of County Kerry in southwestern Ireland, known as Dá Chích Anann ('The Two Paps of Anu' or The Paps of Anu), whose rounded breast-like summits are crowned by prehistoric Bronze Age burial cairns. While the goddess rarely appears as an active, speaking protagonist in narrative sagas (unlike her divine descendants Lugh, the Dagda, or the Morrígan), her matriarchal presence forms the sacred foundation of Irish mythological identity, echoing across major European river names and the maternal figure of Dôn in Welsh tradition.
