The Casa Dario (Palazzo Dario) is situated in the Venetian sestiere of Dorsoduro. It faces the Grand Canal and backs onto the Campiello de Ca'Barbaro. Its construction began in 1487, and it is notable for its façade which is encrusted with disks of green marble and Egyptian porphyry and for its typically large Venetian chimneys. Ruskin refers to its encrustation in 'The Lamp of Beauty' ( Works, 8.153) and illustrates and describes it in the first volume of The Stones of Venice, ( Works, 9.33, 425-6). From 1838-42 it was the home of Rawdon Brown, a close friend of Ruskin, who, having visited Venice to find the tomb of the person described as the banished Norfolk in Shakespeare 's Richard II, spent much of the remainder of his life in the State Archives of Venice cataloguing those papers of interest to English scholars of history. Ruskin compares Canaletto 's rendering of the building unfavourably with the building's reality.
