In 16thcentury sculpture the cathedral is especially rich, containing many statues, groups and altar-reliefs by Simone Mosca and Ippolito Scalza.
The cathedral built by Bartolommeo Ammanati (1S70), modified by Ippolito Scalza, and completed in 1680 (with the exception of the facade, which is still unfinished) contains a large altar-piece by Taddeo di Bartolo of Siena, and the fragments of an imposing monument erected in1427-1436by the Florentine architect Michelozzo in honour of Bartolommeo Aragazzi, secretary of Pope Martin V., which was taken down in the 18th century.
Among the first of these were Antonio Maria Valsalva (1666-1723), still better known as an anatomist; Giovanni Maria Lancisi (1654-1720), also an anatomist, the author of a classical work on the diseases of the heart and aneurisms; and Ippolito Francisco Albertini (1662-1738), whose researches on the same class of diseases were no less important.
And sent his relatives Ippolito and Alessandro, both minors and bastards, to Florence under the tutorship of Cardinal Silvio Passerini.
Ippolito was styled the Magnifico and destined to be ruler of the republic, but Cardinal Passerini's regency proved most unpopular, and the city was soon seething with discontent.
When Filippo Strozzi, and above Second all his wife, threw their influence in the scales against expulsion the Medici, and the magistrates declared for their ex of the pulsion from power, Passerini, Ippolito and Alessandro Medici left Florence (17th of May 1527).
P. Salvolini, insincere and self-seeking, died young, and Ippolito Rosellini (1800-1843) showed little original power.
On the motion, however, of Ippolito d'Este, the papal legate, exception was taken to the further conduct of the negotiations in full conclave; and a committee of twenty-four representatives, twelve from each party, was appointed - ostensibly to facilitate a satisfactory decision.
