[4] He taught at the school of Paris for a while, where at one point a townswoman tried to seduce him, resulting in the medieval writer Gerald of Wales later recounting the humorous story of how Blois resisted the lady's advances.
[3] By the late 1180s, Blois had moved to the household of Hugh of Avalon, the Bishop of Lincoln.
Blois was a subdean, an ecclesiastical official, of the diocese of Lincoln by 22 March 1194,[5] probably from about 1189.
[3] He was named precentor of Lincoln in 1197, in succession to the medieval writer Walter Map.
King John first tried to impose his own appointee, but was unable to force his choice on the cathedral chapter, who were responsible for electing a new bishop.
Blois' acta show him to have been an active and diligent administrator, especially concerned with the establishment of vicarages and with parish care.
He also spent time mediating disputes, including one in 1204 over a church at Eynesbury that was disputed between Saer de Quincy, the canons of Newnham Priory and monks of St Neot's Priory.
