<p>These sketches document three visits to the Mediterranean--in 1928-29, 1950-51, and 1959--which were instrumental in shaping the ideas of Louis Kahn, America's greatest postwar architect. They include Kahn's early drawings of the Tuscan hill town of San Gimignano, whose towers would later appear in his Brutalist buildings; and his later more interpretive and emotion-charged sketches of the Valley of the Kings in Egypt and St. Mark's Basilica in Venice. This catalogue accompanies a December 1996 exhibition of Kahn's drawings with the same title at the Jewish Museum in New York, organized by the authors, who teach art history at Williams College.</p>
