It was in fifteenth-century Florence that Brunelleschi`s buildings and Alberti`s treatise first established the principles of Italian Renaissance architecture in practice and theory. This classic survey of Italian Renaissance architecture ranges from the erection of Brunelleschi`s dome for the Florence Cathedral to the works of Bramante and Leonardo. This book was first published in 1974 as part one of a volume entitled Architecture in Italy, 1400-1600. Part two, by Heydenreich`s pupil Wolfgang Lotz, is being reissued as a separate volume. Heydenreich`s text is now accompanied by a critical introduction and updated bibliography by Paul Davies.
