Aldobrandini, a noble family of Florence in the 16th and 17th centuries. Silvestro, a celebrated jurist, was born at Florence in 1499, and died in Rome in 1558. Being opposed to the duke Alexander de' Medici, he was banished from Florence in 1530. Of his three sons, Giovanni was auditor rotae and cardinal, and is also known as an author; Ippolito became pope under the title of Clement VIII.; and Tommaso, born at Rome about 1540, was papal secretary of briefs, and left a translation of the "Lives of the Philosophers" by Diogenes Laertius, and a commentary on Aristotle, De Physico Auditu. Crazio Passeeo, who died at the beginning of the 17th century, was the son of Silvestro's daughter, took the name of Aldobrandini, and was made cardinal. He was a friend of Tasso, who dedicated to him the Gerusalemme conquistata. His brother Pie-tro was also a cardinal, and legate in France, where he composed the differences between Henry IV. and the duke of Savoy in 1601. The family disappeared in 1681.
