On the first plan we can see 12 persons.One of them is woman.The are a lot of interesting elements of arts.The painter uses round lines in the painting of people.On the back plan  Leonardo da Vinci paint a straight clear lines.The main object is a table.There are 12 persons,sitting at it.In the middle of the table is Jesus and apostles.On the right side from Jesus -his wife Maria.The creator use soft lines,mild colours.
In common with other depictions of The Last Supper from this period, Leonardo seats the diners on one side of the table, so that none of them have their backs to the viewer. Most previous depictions excluded Judas by placing him alone on the opposite side of the table from the other eleven disciples and Jesus or placing halos around all the disciples except Judas. Leonardo instead has Judas lean back into shadow. Jesus is predicting that his betrayer will take the bread at the same time he does to Saints Thomas and James to his left, who react in horror as Jesus points with his left hand to a piece of bread before them. Distracted by the conversation between John and Peter, Judas reaches for a different piece of bread not noticing Jesus too stretching out with his right hand towards it. The angles and lighting draw attention to Jesus, whose head is located at the vanishing point for all perspective lines.
I choose this paint because,the discription of it made a srong impression when I read the book -Leonardo code.This point contains a lot of symbols,a lot of different signs.For example,if we look at clothers Jesus and his wife-it is opposite.(blue and red)It is mean a difference between man and women.
