Bishop Regengerus (Rainerius, Reinherus) was a supporter of the Emperor Henry IV. He first appears as a signatory of the acts of the synod of Brixen, which deposed Pope Gregory VII.

Following the death of Bishop Jacobus, the Chapter of the cathedral elected "W", the Archdeacon of Vercelli, but his candidacy was rejected by the papal legate, Gregorius de Montelongo; an appeal to the pope was impossible, since the papal throne was vacant from August 1241 until 25 June 1243. The Chapter than proceeded to elect Martinus de Advocatis, Provost of the cathedral of S. Eusebio in Vercelli, despite the fact that he was excommunicated and "minus idoneus", not least because his family were repeatedly hostile and violent toward the Church of Vercelli. On 9 June 1244, Pope Innocent IV instituted an investigation into Martin's election as being uncanonical. Bishop Martinus died in July 1268.

He held a diocesan synod in 1600. From 1605 to 1607 he was papal nuncio in Prague. He died in Biella in 1611 (Ughelli, Cappelletti, Eubel). Ughelli IV, pp. 814-815. Cappelletti XIV, p. 419.
