Slavisa Patsy, an information technology expert, has a soft spot for Leonardo da Vinci's portraits. By covering the original with a layer of translucent paint with mirror effect, he produced a peculiar visual effect: two portraits resembling the Templar appeared at both ends of the dining table, one holding a baby and standing on the left side of Jesus. Percy also pointed out that there was a wine glass that Jesus had never seen before. Percy said that the last supper may be a description of the first communion, when Jesus gave his followers bread and wine to represent his body and blood. Percy didn't say he recognized the baby, but many amateur scholars said it was the child of Jesus and his disciple Mary Magdalene. Patsy has no comment on the significance of these seemingly hidden portraits, although he thinks this is the result of Leonardo da Vinci's love of mathematics. As we all know, Leonardo da Vinci was also good at writing from left to right and from right to left, which is called "writing backwards". Percy's speculation may be related to Leonardo da Vinci's habit of backwards writing, but these speculations have caused some problems. Scholar Ada Finch said that with the passage of time, the original work has aged, and it is no longer realistic and delicate, which is not as good as the effect first shown by Leonardo da Vinci. Percy's The Last Supper is distorted and blurred, and the existing aging condition of the original makes the problem worse. Nevertheless, Percy's composite portrait shows something and people. Before dissecting some speculations about The Last Supper, let's examine the history and theme of this painting. Leonardo da Vinci completed this painting from 1494 to 1498. It is a mural of the UNESCO World Heritage-Santa Maria Thanksgiving Church and Dominican Monastery. This painting depicts the famous biblical scene-the Last Supper. Shortly before Jesus was crucified, he ate with his followers because he predicted that a believer would betray him. The Last Supper does show the scene of Jesus making a statement.
