Interior of San Marco, Venice

Canaletto's 1745 interior of the Basilica of San Marco, now in the Montreal Museum of Fine Arts, is among his relatively rare incursions into interior space — a significant technical and compositional departure from the outdoor vedute that formed the overwhelming majority of his output. The Basilica, built in its current form in the eleventh and twelfth centuries and encrusted with Byzantine mosaics acquired from Constantinople and elsewhere, represented an interior environment of extraordinary richness and optical complexity: gold mosaics catching and diffusing light in ways quite different from the crisp architectural surfaces of the canal-side views. Canaletto had worked as a theatrical scene designer before turning to veduta painting, and his ability to render interior space — the volumetric drama of the multiple domes, the mosaic floors, the deep shadow of the narthex — reflects that training. His few interior vedute were particularly prized by collectors who had visited Venice and wished to capture the experience of the Basilica's overpowering interior. The Montreal Museum, which holds one of North America's strongest collections of European painting, acquired this work as part of its eighteenth-century holdings.

Canaletto masterfully renders the complex spatial geometry of San Marco's multi-domed interior using precise one-point perspective. The golden mosaics are suggested through warm tonalities and flickering highlights, while the filtered light creates dramatic contrasts between illuminated and shadowed areas.
