The bay horse has not been identified, although the picture is believed to have been
painted for Arthur Annesley, 9th Viscount Valentia (died 1816). The horse's ears are cropped in accordance with contemporary fashion. The animal is placed in a landscape of mallow and dock, which grow in the shade of a clump of trees in the foreground
on the right. In the background are a lake on the left, and a church and village on the far shore. Basil Taylor (p.214) notes that the background in this work is characteristic of Stubbs's during the following decade.
works usually depicted horses with a groom, jockey or owner, whereas in his later pictures, such as this one, the animals were more often shown in solitude.
