Tracing the layers: The panel represents a single figure of a horse made with large non-deep pecked strokes (layer 1 - red). The figure is represented partially - we can see a head, a neck, a breast line and a front leg. Probably, this image was made during Neolithic.
The horse image is covered with a modern vandalized inscription (layer 2 - green).
A desert tan of the pecking significantly reduced the visibility of the images (Original view). Nevertheless, we can suggest the initial view of the main composition based on new damages. The new pecking was lighter than the intact surface (Reconstruction).
