Born in
Genoa, de Mari was an illegitimate child. According to some sources his paternity was attributed to Domenico de Mari, patrician of Genoa, brother of Teodorina and uncle of Maurizio Cybo, although another source states Maurizio (d. April 1491) was his father. He was made cardinal on 9 March 1489 by his uncle, Pope
Innocent VIII. He built the first
Cybo Chapel in the
Basilica of Santa Maria del Popolo in the beginning of the 16th century which was decorated by the frescos of
Pinturicchio and the works of
Andrea Bregno but was destroyed by
Alderano Cybo in 1682-87. He also was
bishop of Vannes in France,
bishop of Palestrina (1493),
bishop of Albano (1501) and
bishop of Noli (1502). ==References==
