 This repair did not last well and another restoration was attempted in 1770 by an otherwise unknown artist named Giuseppe Mazza.Mazza stripped off Bellotti's work then largely repainted the painting; he had redone all but three faces when he was halted due to public outrage.In 1796, French revolutionary anti-clerical troops used the refectory as an armory and stable; they threw stones at the painting and climbed ladders to scratch out the Apostles' eyes.
