Giovanni Battista Adriani
Giovanni Battista Adriani (1511 or 15131579) was an Italian historian. Life
He was born on August 11, 1823, in Cherasco, into a patrician Florentine family. His father, Marcello Virgilio Adriani (died 27 November 1521), was a professor of literature, and served as chancellor of the Republic. In 1838, he joined the order of Order of Clerics Regular of Somasca and soon became a teacher of philosophy and theology. In 1846-1853, he was a professor of history and geography at Collegio-Convitto di Casale. Giovanni Battista was secretary to the Republic of Florence. He was among the defenders of the city during the siege of 1530, but subsequently joined the Medici party and was appointed professor of rhetoric at the university. At the instance of Cosimo I he wrote in Italian a contemporary history, spanning from 1536 to 1574, which is generally considered a continuation of Guicciardini chronicles, although the historian Brunet finds this notion erroneous. This Istoria dei suoi tempi was published in Florence in 1583; a new edition appeared also in Florence in 1872. De Thou acknowledges himself greatly indebted to this history, praising it especially for its accuracy. Adriani also composed funeral orations in Latin on the emperor Charles V and other noble personages, and was the author of a long letter on ancient painters and sculptors prefixed to the first volume of Vasari. Giovanni Battista's son, named Marcello, born 1533 became a professor of rhetoric at the Accademia Fiorentina. He edited and translated a number of classic texts, including the Trattato dell'elocuzione by Demetrius of Phalerum. Works
