Santa Pudenziana
The new pope was mindful of his obligations to Boso, and soon (no later than 18 March 1166) promoted him Cardinal-Priest of the title of Santa Pudenziana (subscribed the bulls with this title between 18 March 1166 and 29 July 1178). Boso, though dismissed as camerlengo, was subsequently entrusted with several important missions in Northern Italy (1160/61, 1162, 1173/74, 1177). When Alexander made his journey to Venice to receive the submission and allegiance of the Emperor Frederick II, and to ratify the Peace of Venice (24 June 1177) which closed the schism, he was accompanied by Boso.
