Often an artist will swipe/quote from another, either as homage, parody, necessity of purpose, or lack of imagination. Here is the first entry in the series "Swipe Spot".
1807, Friedland painted by Meissonnier while at the apex of his career. Note the white horse on the right and its rider.
The Revenge (The Escape) a work done by George de Forest Brush at the beginning of his career. Note how he has transposed a swipe.
...and the figure
The Arab Falconer,1864 by Eugène Fromentin, an artist much celebrated in his time though seldom mentioned today.
