Leonardo da Vinci's famous painting of the `”Last Supper” is kept in the Monastery of Santa Maria delle Grazie, in Milan. Jesus Christ is depicted with his disciples sitting down to their last meal on the eve of his execution. According to legend, the artist saw a beautiful image of Jesus in the face of a young choir singer. Three years later, when the painting was almost finished and no appropriate model for Judas could be found, Leonardo saw a tramp lying in a ditch and painted the desired image of him. When the poor man woke up, it turned out that he was the same choirboy who had posed for the artist three years earlier, but had subsequently lost his dignity and sunk to the bottom of society. Good and Evil may have the same face — it all depends on the moment in which they meet each of us.
