Polish Enlightenment in the context of "Constitution of 3 May 1791 (painting)"

The Constitution of 3 May 1791 (Polish: Konstytucja 3 Maja 1791 roku) is an 1891 Romantic oil painting on canvas by the Polish artist Jan Matejko. It is a large piece, and one of Matejko's best known. It memorializes the Polish Constitution of 3 May 1791, a milestone in the history of the Polish–Lithuanian Commonwealth and a high point of the Polish Enlightenment.

Like many Matejko works, the picture presents a grand scene populated with numerous historic figures, including Poland's last King, Stanisław August Poniatowski; Marshals of the Great Sejm Stanisław Małachowski and Kazimierz Nestor Sapieha; co-authors of the Constitution such as Hugo Kołłątaj and Ignacy Potocki; and other major contemporary figures such as Tadeusz Kościuszko. Some twenty individuals have been identified by modern historians; another ten or so who had been reported in older sources as being present, await definitive identification.
