Scene from Roman history? A man mounting a horse held by a nude man 1775 - 1825

This anonymous drawing from the 18th century depicts a scene of a man mounting a horse. The figure is clad in a simple garment and is being assisted by a nude man. A decorated saddle and other details suggest a Roman setting, and the composition of the figures is reminiscent of classical art. The drawing is made with pen and brown ink on paper and is a fine example of the work of an anonymous artist. The drawing, currently housed at the Statens Museum for Kunst in Denmark, is a valuable example of the study of anatomy and movement during the 18th century.
