Premise: One of Tintoretto's best, the Marriage at Cana, is on the wall opposite the entrance, while three of Titian's most vivid canvases decorate the Cain and Abel, Abraham Sacrificing Isaac, and David and Goliath, their drama heightened by the perspective di sotto in su (looking up from below).

Hypothesis: The Marriage at Cana was painted by Titian.
