Warmund was a Catholic bishop of Ivrea who lived from approximately 930 to 1011. Born in Vercelli, he served as the leader of the Ivrea see starting around 966. He is most famously remembered as the namesake of the Warmund Sacramentary, a highly decorated manuscript created for him near the year 1000. His tenure was marked by significant architectural projects at the cathedral in Ivrea and a notable political conflict with the margrave Arduin, which led to his use of excommunication.
Life and work


During his episcopate, Warmund oversaw the reconstruction of the Ivrea cathedral, including the choir, crypt, and ambulatory. He also commissioned the building of twin bell towers. His leadership faced a major challenge when Arduin, the margrave of Ivrea, forced him from his position due to land disagreements. Warmund responded by excommunicating the margrave, a move supported by the Pope and Emperor Otto III.
Legacy and veneration

The Warmund Sacramentary remains a vital historical resource, particularly for researchers studying medieval burial customs. Warmund was beatified in 1857. He is commemorated in the Catholic tradition on 13 November, alongside other bishops of Ivrea.
