The Polish Rider

The Polish Rider is a seventeenth-century painting, usually dated to the 1650s, of a young man traveling on horseback through a murky landscape, now in the Frick Collection in New York. When the painting was bought by Henry Frick in 1910, there was consensus that the work was by the Dutch painter Rembrandt. This attribution has since been contested, though this remains a minority view.
