Luca Carlevariis was the first painter of Italian origin to specialize in views of Venice. The artist's many precise renditions of the city reveal his early training as a mathematician. His painting of the Piazzetta places the viewer in a boat on the Grand Canal, looking north toward the Piazza of San Marco. The direction of the shadows from the southwest-indicates that the time is afternoon. On the left are the library of Sansovino, the lower portion of its Campanile, and the column of Saint Theodoric. To the right are the south side of Saint Mark's Basilica, the Doge's Palace, and the column of Saint Mark. The buildings, though not entirely accurate in certain architectural details, remain largey unchanged to this day.
