I find Wikipedia a great data base giving information which no other encyclopedia would give.
I do my bit when somebody tries to mutilate (not edit) an article by, for instance, deleting whole paragraphs or links just because he/she does not like it.
The Death of Marat is a 1793 painting by Jacques-Louis David depicting the artist's friend and murdered French revolutionary leader, Jean-Paul Marat. It was painted when David was the leading French Neoclassical painter, a Montagnard, and a member of the revolutionary Committee of General Security. Created in the months after Marat's death, the painting shows Marat lying dead in his bath after his murder by Charlotte Corday on 13 July 1793. Art historian T. J. Clark called David's painting the first modernist work for "the way it took the stuff of politics as its material, and did not transmute it".Painting credit: Jacques-Louis David
