Ludovico Trevisan

Ludovico Trevisan (November 1401 – 22 March 1465) was an Italian Catholic prelate, who was the Camerlengo of the Holy Roman Church, Patriarch of Aquileia and Captain General of the Church (commander-in-chief of the Papal Army and the Papal Navy). He succeeded his rival Giovanni Vitelleschi, a fellow cardinal of military talent and inclination, as Bishop of Traù and Metropolitan Archbishop of Florence. Trevisan was also known as the Cardinal of Aquileia and the Cardinal Camerlengo. Like other war cardinals, such as Niccolò Fortiguerra and Giuliano della Rovere, Trevisan came from a humble background. His mother's maiden name was Mezzarota.

On 4 June 1440 he received a special military standard and proceeded to Tuscany with a force of 3000 horsemen and 500 foot soldiers to support Francesco I Sforza and other papal and Florentine condottieri against Niccolò Piccinino.

Cardinalate Antonio Rido, a henchman of Trevisan, depicted on his tomb in San Pancrazio, Rome. Immediately afterwards, on 1 July 1440, Trevisan was elevated cardinal priest, title of S. Lorenzo, by Pope Eugene IV and a medal in his honour was designed by Cristoforo di Geremia to commemorate the victory. Trevisan defeated the Turkish assault on Mytilene in August 1457, during which many Turkish vessels were captured, receiving praise from the pope.

Death and legacy Trevisan died during the first year of the pontificate of Pope Paul II, with whom Trevisan was not on good terms, at 3 a.m. in Rome of edema. Like Cardinal Gil Álvarez Carrillo de Albornoz, Trevisan has been described as an "angel of peace".
