In Liber miraculorum sancte Fidis (early eleventh century) Bernard d'Angers makes a physical description of a cleric, whom he delivers a topical portrait corresponding to an ideal measurement and proportion. However, the same author praises for the beauty of a knight, whose stature and physical power he insists on. So we are dealing with two opposing male aesthetic canons. To understand this contrast, we must put Bernard's text into perspective by placing it both in the literary tradition it is the heir of and in its Christian theological context. This leads to the conclusion that the ideal of fair measure is the world of the clergy's own, for whom the body reflects the soul. On the other hand, a comparison with the Vita Karoli and the Chanson de Roland can show that the laics are the ones who associate a tall and muscular body to the idea of male beauty.
