----------------------------Original message---------------------------- Thanks to those who helped answer my question. Sir Banister Fletcher's History of Architecture (20th ed., 1996) has a section with a scale on page 913. By the way, the index does not cross-reference building names under architects. Thus, the building is indexed under its locality, i. e., Turin, only, and not under the name of its architect, Guarini. --Paul Glassman Art & Architecture Librarian Pratt Institute 200 Willoughby Avenue Brooklyn, New York 11205 Telephone (718) 636-3714 FAX (718) 399-4401
