Andrea Corsini (30 November 1302 – 6 January 1373 or 1374[2][3]) was an Italian Catholic prelate and professed member from the Carmelites who served as the Bishop of Fiesole from 1349 until his death.

[4] Corsini led a wild and dissolute life until a rebuke from his mother moved him to go to the Santa Maria del Carmine church where he resolved to join the Carmelites as a priest and friar.

He went to the Carmelite monastery at the Santa Maria del Carmine church to consider what course to take and despite the entreaties of his dissolute friends, decided to become a friar.

This perhaps gave rise to the legend that he fled, and that a child discovered him at the charterhouse at Enna, and he later accepted the nomination as bishop as the result of a vision.

At Fiesole, just northeast of Florence, he gained a reputation as a peacemaker between rival political factions and for his care of the poor.

[6] "His family connections made him acceptable to the nobility and his life of poverty endeared him to the poor and he did succeed in bringing peace.

[10] It was reported that in 1372 or 1373,[3] as he celebrated Midnight Mass on Christmas Eve, that the Blessed Virgin appeared to him and told him he would leave this world on the Three Kings' feast.

Among the miracles attributed to Corsini's intervention was the Florentine victory over the Milanese at the Battle of Anghiari on 29 June 1440.

Pope Clement XII - born Lorenzo Corsini - erected in the Roman Basilica of Saint John Lateran a magnificent chapel dedicated to his kinsman.
