Celtic Yule Ritual
Winter Solstice is called "Mean Geimredh", mid-winter, in Irish, "Alban Arthan", the point of roughness, in Wales, "Modranicht", mother night, to the Anglo-Saxon's, "Deuorius Riuri", great divine winter feast, in the Coligny Calendar and "Yule." The word "Yule," according to Bede and various other authorities of the olden time is derived from an archaic Norse word "Jol," meaning "a wheel."
The Winter Solstice represents the rebirth of the sun, which is a particularly important turning point. The night of Solstice is the longest night of the year. Darkness triumphs; and yet, gives way and changes into light.
