Man, just think how much faster that whole "Last Supper" thing would go now - few minutes?

Leonardo worked on The Last Supper from about 1495 to 1498, but did not work continuously. The beginning date is not certain, as the archives of the convent for the period have been destroyed. A document dated 1497 indicates that the painting was nearly completed at that date. One story goes that a prior from the monastery complained to Leonardo about its delay, enraging him.
