caption: The image shows a painting of three men standing next to each other, each holding a book in their hands. The painting is believed to be a representation of the three evangelists, with each man wearing a different colored robe and a halo of light around their heads. The background of the painting is a deep blue, and the figures are standing in a line, with the man in the middle wearing a white robe and the two men on either side wearing green robes. The figures are surrounded by a golden halo, which gives the painting a regal and majestic feel.
