St Catherine of Alexandria.

From the tenth century onwards veneration for St. Catherine of Alexandria has been widespread in the Church of the East, and from the time of the Crusades this saint has been popular in the West, where many churches have been dedicated to her and her feast day (25 November) kept with great solemnity. She is listed as one of the Fourteen Holy Helpers of mankind among the saints in Heaven; she is the patroness of young women, philosophers, preachers, theologians, wheelwrights, millers, and other workingmen. She was said to have appeared with Our Lady to St. Dominic and to Blessed Reginald of Orleans; the Dominicans adopted her as their special protectress. Hers was one of the heavenly voices heard by St. Joan of Arc. Artists have painted her with her chief emblem, the wheel, on which by tradition she was tortured; other emblems are a lamb and a sword. St. Catherine's remains are in St. Katherine's Monastery on Mt. Sinai. The Monastery, a 1,600-year old fortress at the base of Mt. Sinai is inhabited by Coptic monk. Inside the chapel is believed to be the Burning Bush, through which God first appeared to Moses. This window of St Catherine is in Leicester Cathedral.
