He was the son of Betton, Count of Tonnerre, "Blessed Betto," a member of the royal house of the Kingdom of Burgundy.

[3] The Romanesque church dedicated to Saint Loup at Naud, 8 km from Provins in Champagne in the east of France is distinguished by the outstanding sculptures in the porch of its great doorway, with an ambitious iconographic program in which Saint Loup mediates entry into the mystery of the Trinity.

About 980, Sevinus, archbishop of Sens, made a gift to the Benedictine community of the abbey of Saint-Pierre-le-Vif at Sens of four altars in villa que dicitus Naudus, in honore sancti lupi consecratum—"in the demesne that is called Naud, consecrated in honor of Saint Loup"—betokening the presence of a shrine already on this site, a priory under the direction of the abbot of Saint-Pierre-le-Vif.

Other documents mention Saint-Loup-de-Naud among the possessions of the abbey at Sens, seat of an archbishop with close political ties to the French Crown, who had Paris within his diocese.

In 1160/61 Hugues de Toucy, Archbishop of Sens, presented to the priory the relic of Saint Loup, brought from the abbey of Sainte-Colombe, to that community's dismay;[4] the sculpted portail with an iconography comparable to the royal portal at Chartres[5] was doubtless undertaken shortly thereafter, when pilgrimages brought wealth to the community.
