caption: The image shows a painting of a white horse with a saddle on its back, painted by John Singer Sargent. The horse is standing in a stable, with its head held high and its mane and tail flowing in the wind. Its eyes are focused on something in the distance, and its hooves are firmly planted on the ground. The saddle is a deep brown color, and the horse's coat is a lighter shade of brown. The background is a light blue, giving the painting a peaceful and calming atmosphere.
