St. Bridget was known as the Celtic saint of well-being with this cross being her symbol. The orginal equal-armed cross was woven with rushes from the river Shannon. Her feast day is February 1st although some celebrate her holiday, Candlemas, on February 2nd. It is tradition in Ireland to hang a St. Bridget's cross over your door to ensure good health throughout the year.
The Old Celtic Tradition of Handfasting from where we get the phrase "Tying the Knot" is becoming popular in Irish Weddings again.
