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: "These paintings are worth anywhere from ten million to forty million each." is true, false, or inconclusive?
