TARLATI DI PIETRAMALA, GALEOTTO. – Cardinal, son of Magio, born at Arezzo, died at Vienne in Dauphiné in 1396.
He belonged to a Ghibelline family that held sway in Arezzo from the eleventh to the fifteenth centuries, and he himself took an active part in the tumultuous life of his city. Having entered the ecclesiastical career at a young age, on 18 September 1378 Urban VI made him cardinal deacon of the title of S. Agata. In 1386 T. and Cardinal Pileo di Prata rebelled against the Pope, who had had five cardinals put to death in Genoa, and first took refuge in Pavia, from where they wrote the Bolognese a violent letter against Urban (8 August 1386; published in Historisches Jahrbuch, 16 [1893], pp. 827–31), and then went to Avignon to the antipope Clement VII, who recognized them in their cardinalitial dignity. T. received the title of S. Giorgio al Velabro and many benefices. In Avignon he took part in the election of the antipope Benedict XIII, in whose favor he sent a letter to the Romans (1394; in E. Martène - U. Durand, op. cit. in bibl., I, cols. 1343–45), and participated in a commission intended to put an end to the schism. He was a man of virtue and learning, and was highly esteemed in his time.
