The Death of Sardanapalus,  Eugene Delacroix.  1827.  Used extremely well in the "Runaway Horses" sequence of the movie Mishima.  This painting has it all.

The Raft of the Medusa, Theodore Gericault, 1819.   This commemorates a French naval disaster caused entirely by a fool of a captain, De Chaumerays.  He had not held a command for over 20 years and managed to pile up his ship on the Arguin Bank, mainly because he listened to a passenger and not his experienced officers.  The shore of Africa was only a few miles away.  The lifeboats could have ferried all aboard to safety in a couple of days.  Instead, the boats towed a huge raft with 150 souls on it.   Tiring of the labor, they slipped their cables and left the men to die.  All but 10 did.  Although this was the fault of the Ministry of Marine, Louis 18th caught the anger of the French nation.  It was a political bombshell, and this painting fanned the flames.  Well done, Theo.  The ship was still intact when ships arrived to salvage it, with several survivors alive.  All for nothing.

Watson and the Shark.  John Singleton Copely, 1778.  I have stood in front of this and it is one huge fucking painting.  But below James Rosenquist shows us how huge is done downtown!

James Rosenquist, F-111, 1965.  10' X 86'.  Ho hum.  Americans are consumers so that causes wars, right?  I think a picture of Lyndon Johnson and his rubber stamp government a more appropriate symbol of pure mindlessness resulting in evil.
Rosenquist used to paint billboards.  I have liked this painting since, well, the war started!
