"William of Gellone (c. 755 – 28 May 812 or 814 AD), the medieval William of Orange, was the second Duke of Toulouse from 790 until 811. In 804, he founded the abbey of Gellone. He was canonized a saint in 1066 by Pope Alexander II.
In the tenth or eleventh century, a Latin hagiography, the Vita sancti Willelmi, was composed possibly based on oral traditions. By the twelfth century, William's legend had grown. He is the hero of an entire cycle of chansons de geste, the earliest of which is the Chanson de Guillaume of about 1140. In the chansons, he is nicknamed Fièrebrace (fierce or strong arm) on account of his strength and the marquis au court nez (margrave with the short nose) on account of an injury suffered in battle with a giant." - (en.wikipedia.org 23.12.2020)
