有谁知道法国作家Béroul的生平资料啊？帮帮我啊，谢谢啦~

Béroul was a Norman poet of the 12th century. He wrote Tristan, a Norman language version of the legend of Tristan and Iseult of which a certain number of fragments (approximately 3000 verses) have been preserved; it is the earliest representation of the so-called "vulgar" version of the legend (the "courtly" version being represented by fragments from Thomas of Britain's poem). Eilhart von Oberge wrote a treatment of this version in German, and many of Béroul's episodes that do not appear in Thomas reappear in the Prose Tristan.
