Based on an early modern Milanese chronicle, it is sometimes argued that Amizo was the son of Arduin Glaber of Turin.
[1] Sometime between 983 and 987, Amizo consecrated abbey of Sacra di San Michele, founded by Hugh of Montboissier.
[2] In 989 Amizo granted the parish of S. Maria di Quadraciana to the nuns at San Pietro in Turin, enriching them with property at Scarnafigi and Cervignasco.
[3] Amizo obtained two imperial diplomas confirming the church of Turin in all its possessions: the first was issued by Otto II in 981, and the second by Otto III in 998.
[4] In 997 Amizo participated in the synod of Pavia, presided over by Pope Gregory V.[5]
