The gods, symbols, festivals and folklore of Celtic Britain and Ireland, gathered in one place
The Celtic world runs through so much of modern practice, from the Wheel of the Year to the knots and spirals people still carve, wear and draw today. This is where every Grove guide on it lives: the gods and goddesses of Ireland and Britain, the symbols cut into ancient stone, the Ogham letters, the Sidhe of the hollow hills and the four fire festivals that still mark the turning year. Start with whatever catches your eye and follow the links from there.
Celtic Gods and Goddesses
The deities of Ireland and Britain are tied to the land itself: to rivers, hills, wells and the turning seasons. Most of their stories come down to us through medieval Irish and Welsh writing, alongside carvings and inscriptions far older. For an overview of them all, read the Celtic gods and goddesses guide.
