This study explores the profound, and continuing, influence of classical Greek and Roman design and construction techniques on postmodern and neomodern architecture throughout the western world. Architects, interior designers, and builders should find refreshing insights on the theory of imitation and its role in traditional and modernist art, tectonics in architecture, the classical order, character and style, as well as the traditional city. A detailed appendix features works of Plato, Cicero, Alberti, Hegel, and other great classicists.
