Aristotile Fioravanti (ca. 1415 or 1420 – ca. 1486) was an architect and engineer from Italy. His name is also given as Aristotele Fioravanti or Aristotle Fioravanti. His surname is sometimes given as Fieraventi. Russian versions of his name are Фьораванти, Фиораванти, Фиеравенти, Фиораванте.
He came from a family of architects.
He created the plans for the reconstruction of the Palazzo del Podestà in Bologna, but the reconstruction was not carried out (by Giovanni II Bentivoglio) until 1484–94.
In 1475 at the invitation of Ivan III he went to Russia, and built the magnificent Assumption Cathedral (aka Dormition Cathedral) (Uspensky Sobor) in Moscow from 1475–1479, taking inspiration from the cathedral in Vladimir. This is the work he is best remembered for.
According to some accounts, he was thrown into prison by Ivan III when he asked to return to Italy, and died in captivity. According to other accounts, he participated as a military engineer and artillery commander in the campaigns against Novgorod (1477–78), Kazan (1482) and Tver (1485).
During the first effort, the unfinished walls of the cathedral collapsed, and in 1475, Ivan III commissioned the Italian Architect AristotileFioravanti to build the new one.
Fioravanti studied churches in several of the ancient Golden Ring towns, and patterned the new Cathedral after the Cathedral of the Dormition in Vladimir.
Fioravanti was thrown in prison after asking to return to Italy, and he died there in 1486.
