20 paintings by Canaletto together with 34 paintings by his contemporaries, including Gaspar Vanvitelli, Luca Carlevarijs, Michele Marieschi, Bernardo Bellotto, and Francesco Guardi, were shown in this exhibition, which explored cityscapes of Venice and the styles and rivalries of the artists. Works on view were from the collection of the National Gallery of Art, and loans from public and private collections in Europe and the United States. 2 historical cameras obscura, on loan from the Museo Correr, Venice, also were shown, together with 3 modern examples to illustrate use of the tool in creating accurate landscape images. A 35-foot-long gondola that once belonged to the American painter Thomas Moran, on loan from the Mariners' Museum, Newport News, Virginia, was shown on the East Building Mezzanine. The exhibition was part of ITALY@150, a series of activities in Washington, DC, and throughout the United States celebrating the 150th anniversary of the unification of Italy.
