the painting you describe is the one i am picturing in my mind... (and not the one i got the url for)

since "death of Marat" doesn't link to that image, i can only think it has some other name.. i hope some one can find it..

it interesting, how painting can haunt us, the visual image lives on.. and yet we forget the name..

how right Dali was with the idea of "the Persistence of Memory"...
