Vereshcagin Vassily

Vasily Vasilyevich Vereshchagin (Russian: Васи́лий Васи́льевич Вереща́гин, October 26, 1842 – April 13, 1904) was one of the most famous Russian battle painters and one of the first Russian artists to be widely recognized abroad. The graphic nature of his realist scenes led many of them to never be printed or exhibited.
