The Age of the Masters was the age of an architectural revolution that lasted over fifty years - from Charles Rennie Mackintosh's Glasgow Art School at the beginning of the century to Mies van der Rohe's National Gallery in Berlin at the end of the sixties. While they lived, the Masters comprised some of the most powerful architectural talents the Western world has yet produced, and at least two men of towering genius - Frank Lloyd Wright and Le Corbusier. Their aspirations for the future of men, cities, and society may have been thwarted, but the prototypes they created still reflect the light of their creative fervor.
