Huysmans, Corneille (Flemish, 1648-1727)1 Corneille Huysmans

The picture has something of this: water, underwater, tree, nature, tropical, fish, coral, sea, landscape, ocean, reef, light, environment, outdoors, river, exotic, wood.
Perhaps it’s a painting of a man riding on the back of a white horse next to a wooded area with a dog on the other side of the painting.
