There have also been other popular speculations about the work. It has been suggested that there is no cup in the painting, yet Jesus' left hand is pointing to the Eucharist and his right to a glass of wine. (There are several glasses on the table, but they are difficult to see owing to the work's deterioration and restorations.) This is not the glorified chalice of legend as Leonardo insisted on realistic paintings. To add realism, Leonardo copied the style of the plates, glasses, utensils and the table cloth from the Dominican friars' refectory.
