Tutte l'opere d'architettura et prospetiva
Tutte l'opere d'architettura et prospetiva (All the Works of Architecture and Perspective) is an architectural treatise by Italian Renaissance architect Sebastiano Serlio (1475–1554). Serlio is sometimes regarded as one of the most important. The treatise is composed of eight books, the sixth of which was lost for some centuries and the eighth of which was not published until relatively recently. The eighth book is not always considered to be part of the treatise. The first five books cover Serlio's works on geometry, perspective, Roman antiquity, the orders and church design. The sixth illustrates domestic designs ranging from peasant huts to royal palaces, providing a unique record of Renaissance house types, including up-to-date fortresses for tyrants and mercenaries as well as Serlio's unbuilt design for the Louvre. The seventh book illustrates a range of common design problems ignored by past theorists, including how to remodel, or 'restore', Gothic façades following antique principles of symmetry and proportion. The eighth book, called "Castrametation of the Romans", reconstructs a Roman encampment after the description by Polybius, followed by a military city and monumental bridge supposedly built by the Emperor Trajan. With its forum, consul's palace and baths, the book is part-fantasy and part-archaeology, quite unlike Serlio's other more practical works.
