The image is a mosaic on the wall of a building. The mosaic is in the shape of an arch and is made up of small squares and rectangles. It depicts a scene from ancient Greek mythology.

In the center of the mosaic, there is a large figure of a man on a horse, wearing a red robe and holding a sword. He is standing on a rock and appears to be leading the horse. The horse is white with a red mane and tail, and it is galloping forward with its mane flowing in the wind. On the right side of the image, there are two figures, one of which is holding a basket of fruit and the other is standing next to it. The figures appear to be engaged in a battle, with one of them holding a spear and another holding a shield. The background is filled with green plants and foliage, and there are several other figures in the background, including a woman in a red dress and a man in a blue robe. The overall color scheme is predominantly red, green, and yellow, with some hints of blue and green.
