ANTONINUS, SAINT [Antonio Pierozzi, also called de Forciglioni] (1389-1459), archbishop of Florence, was born at that city on the 1st of March 1389. He entered the Dominican order in his 16th year, and was soon entrusted, in spite of his youth, with the government of various houses of his order at Cortona, Rome, Naples and Florence, which he laboured zealously to reform. He was consecrated archbishop of Florence in 1446, and won the esteem and love of his people, especially by his energy and resource in combating the effects of the plague and earthquake in 1448 and 1453. He died on the 2nd of May 1459, and was canonized by Pope Adrian VI. in 1523. His feast is annually celebrated on the 13th of May. Antoninus had a great reputation for theological learning, and sat as papal theologian at the council of Florence (1439). Of his various works, the list of which is given in Quétif-Echard, De Scriptoribus Ord. Praedicat., i. 818, the best-known are his Summa theologica (Venice, 1477; Verona, 1740) and the Summa confessionalis (Mondovi, 1472), invaluable to confessors.
