Vitelmo may have been the son of Vitelmo-Bruno of the Baratonia, a powerful viscount in Turin.
[1] Vitelmo was appointed bishop of Turin by Henry IV.
According to the contemporary chronicler, William of Chiusa, Vitelmo paid a large sum of money in return for his office.
[2] Like many of his predecessors, Vitelmo made donations to the monastery of Santa Maria in Cavour, which had been founded by Bishop Landulf of Turin.
[3] Vitelmo also continued the conflict with Abbot Benedict II (r.c.1066-1091) of the monastery of San Michele della Chiusa, which had begun under Bishop Cunibert of Turin.
