Warmund

His first recorded act was signing the canons of the synod of Milan in absentia in November 969, but he was probably consecrated as bishop on Sunday, 7 March 966.

[4] In the eleventh century, a scribe added the note that "Warmund is consecrated bishop"[5] beside the Nonas marcii ("nones [i.e., the 7th] of March") in the calendar preface to a ninth-century copy of the Martyrology of Ado.

He also performed work on the ambulatory and crypt, and it is probably in connexion with his renovations that he commissioned the scriptorium to produce a sacramentary and other texts for the new altars.

[8] In 999, Peter, the bishop of Vercelli, was killed when Arduin's men besieged his town and burned down his church with him and his canons inside.

[11] On 9 July 1000, the Emperor Otto III confirmed in a diploma that the city of Ivrea belonged to the jurisdiction of the bishop.
