Art has long been a powerful medium for conveying hidden messages and meanings. From ancient cave paintings to Renaissance masterpieces, artists have used symbols as a way to communicate complex ideas and emotions. Take for example Leonardo da Vinci's famous painting, "The Last Supper." While on the surface it depicts Jesus sharing a meal with his disciples, upon closer inspection, there are subtle cues that hint at deeper symbolism. The positioning of hands, the arrangement of figures, and even the use of color all contribute to a narrative that goes beyond mere representation.
