According to the notice of his death, he had been archbishop for five years, one month, and twenty-three (or twenty-four) days, which, calculated backwards, places the beginning of his tenure in July or August 974, depending on whether it is dated from his election or consecration. His predecessor, Arnulf I, died on 16 April 974. Gotofredo's episcopate was marked by his continued support for the Ottonian dynasty and for German rule of Italy. He died in 979 and was buried in Santa Maria Iemale. He was the last of a series of seven politically active archbishops before a period of quiet descended on the Ambrosian see.[1]
