Otto left Rome on 14 February 962 to bring Berengar II to heel. Before leaving he suggested that John, "who passed his whole life in vanity and adultery", give up his worldly and sensual lifestyle. John ignored this advice and watched with increasing anxiety as Otto quickly drove Berengar out of the Papal States. Growing ever more fearful of the emperor's power, he sent envoys to the
