Ilya Repin's portrait of Pavel Tretyakov (1883).
157 years ago today, on May 22, 1856, Pavel Tretyakov acquired a series of paintings that came to mark the founding of the Tretyakov Gallery. Tretyakov's collection, which comprised of more than 1,200 paintings, 518 drawings and nine sculptures, was moved to Moscow in 1892 and has since expanded to include more than 100,000 pieces.
