Ivan Sergeyevich Leontyev, Russian Major General. 

This portrait of Ivan Sergeyevich Leontyev, a Russian Major General, was painted by George Dawe, a prominent British artist who worked in Russia during the early 19th century. Dawe was known for his portraits of prominent figures of the Napoleonic Wars, and this work exemplifies his characteristic style, capturing the sitter's stoic expression and military regalia with meticulous detail. The artwork is housed in the Hermitage Museum in Saint Petersburg, a testament to the artist's lasting impact on Russian portraiture.
