Art is everything. It's impossible to look anywhere in this world and not see an artist's creation or some aspect of art. It allows everybody to express themselves in any way necessary. Art doesn't discriminate or stereotype or hate, it provides an outlet for all emotions under the sun. Without art, the world would be without color, design, literature, music, poetry, dance, everything.
In 1495, Leonardo Da Vinci began painting the Last Supper on the wall of the refectory (dining hall) of Santa Maria delle Grazie in Milan, Italy, and completed it in 1498. Leonardo was commissioned to execute the painting in the Dominican monastery of this Church by Duke of Milan, Ludovico Sforza. The church and friary found an ambitious patron in Ludovico Sforza. The Duke wanted to give visible expression to his position in both impressive buildings like the grand Church and grandiose paintings like the Last Supper. Therefore, Santa Maria delle Grazie became the court church, burial place for members of the Ducal family, and home to Leonardo's famous painting. The Last Supper was painted on the northern wall of the refectory. It measures fifteen by twenty-nine feet. It stands whole as of today, except for the construction of a doorway in 1653, eliminating the lower central area of the painting.
Leonardo's method of working on the Last Supper was unprecedented. The Last Supper is not a fresco. Leonardo's intense concentration and hesitant manner of execution did not suit the commonly used medium for mural painting, in which the pigment had to be applied quickly before the plaster dried, precluding any changes during the course of execution. Instead of fresco, Leonardo devised his own technique for mural painting, a sort of tempera on stone.
The wall was first coated with a strong base of some material which would not only absorb the tempera emulsion but also protect it against moisture. His base was compounded out of gesso,
