Grimaldi, Agostino a Genoese prelate, third son of Lambert, prince of Monaco, studied belles- lettres and theology, and became a particular friend of cardinals Bembo and Sadolet. In 1505 he was elected abbot of Lerins, and assisted in 1512 at the Council of Lateran. On account of some political offence, Francis I deprived him of all his revenues in France. Charles V indemnified him by giving him the bishopric of Majorca and the archbishopric of Oristano; he had even designated him to pope Clement VII as cardinal, but Agostino died before his promotion, probably of poison, April 12, 1532. There are extant of this prelate several letters to illustrious men of his time. See Hoefer, Nouv. Biog. Generale, s.v.
