Take the following as truth: To the left is the stately Maest?  (Madonna Enthroned; 1315) and to the right, Guidoriccio da Fogliano (1328, but whose authenticity has recently been disputed), depicting the Sienese captain's ride to a historic victory at Montemassi in the nicely detailed Tuscan landscape, notice the little Chianti vineyard in the military encampment.
Then the following statement: "To the left is the Van Gogh, on the right is the Mona Lisa, and to the right, Monet." is true, false, or inconclusive?
