The city of Pienza, which the humanist Enea Silvio Piccolomini had built at his birthplace as Pope Pius II (1458-1464), is considered to be the first Renaissance ideal city. Here for the first time the urban interior of a piazza opens on to open countryside, & also for the first time in the history of modern building, architecture & nature are seen as complementary opposites. Fundamental early Renaissance architectural ideas like the classical church facade following the scheme of the ancient triumphal arch or the block-like isolation of a palace in the manner of a Roman insula are formulated with total clarity here for the first time & brought together in one project. One might think that this incunabulum of modern urban architecture has been so central to the view of architectural & art history that there is nothing more to document, or even to research here. But this is true only of a series of individual art-historical problems. While painting & sculpture have definitely drawn the interest of large-scale treatment in work monographs, architecture & urban development have so far been the subject only of short works or individual essays. So far there has been no precise survey of the project as a whole, the essential basis of any academic analysis of architecture. And so it is not surprising that even fundamental typological details of the architecture of Pienza have not been noted.

But when even the facts have scarcely been recorded, the truly interesting questions of architectural history like style, structure & iconography cannot be considered. This volume is the first comprehensive monograph that does justice to all aspects of Pius II's creation.
