The museum has Canova’s 1808 funerary stelae featuring gorgeous women dabbing their eyes with their cloaks, Tullio Lombardo’s wide-eyed 1505 saint whom Titian is said to have referenced for his Madonna at I Frari, and three brooding Tintoretto canvases: Last Supper, with a ghostly dog begging for bread; the gathering gloom of Agony in the Garden; and the abstract, mostly black Washing of the Feet .
