The National Gallery of Art, Washington, will present 20 of Canaletto's finest paintings of Venice with 33 by his most important contemporaries, including Gaspar Vanvitelli, Luca Carlevarijs, Michele Marieschi, Bernardo Bellotto, and Francesco Guardi, in 'Venice: Canaletto and His Rivals,' on view from February 20 through May 30, 2011, in the East Building. These dazzling cityscapes represent the best view painters of Venice—each responding to the city in his own way, and each competing in a market driven largely by the British Grand Tour, at its height during the 18th century.
