The Empress Elizabeth of Russia on Horseback, Attended by a Page
The Empress Elizabeth of Russia on Horseback, Attended by a Page is an equestrian painting of 1743 in the Tretyakov Gallery, Moscow, with several replicas. Done in oil on canvas by Russo-German painter Georg Christoph Grooth, the work depicts Empress Elizabeth of Russia on horseback. The empress is shown dressed in military uniform, attended by a negro page. Elizabeth is shown to be in command of the horse, while her holding of a field marshall's baton represents her command over the sea. The painting was a notable success for Grooth, a former art curator turned painter. The version in the collection of the Metropolitan Museum of Art is also attributed to Grooth, dated to the years after 1743. References
