The Sentinel at the Sultan’s Tomb by Jean Leon Gerome in the year 1880. The subject of this painting is a 15th-century mausoleum in Boursa, Turkey. It shows two men holding a religious vigil, making their prayers in front of the tomb of the deceased sultan. The light seems to come from behind the viewer, and our eye is drawn to the bright colors of the tomb and the flags. The precise details of the costumes and the realistic style make it seem like the stage setting of a play.
