 Grosolanus was the abbot of Ferrania and already Bishop of Savona when Anselm appointed him to act as his vicar during the crusade.Grosolanus was accused of simony in obtaining the Ambrosian see by the priest Liprand, who proceeded through the ordeal of fire to prove his charges.This tale is probably an invention of Landolfo Iuniore, bearing little resemblance to reality, save the fact that Grosolanus was opposed by a strong faction in the city.
