David Holding the Head of Goliath, Michelangelo Merisi da Caravaggio, oil on canvas, 1610, 49”x40” (at the Galleria Borghese)
La Mort de Marat (The Death of Marat), Jacques-Louis David, oil on canvas, 1793, 64”x50” (at the Royal Museums of Fine Arts in Brussels)
Ophelia, John Everett Millais, oil on canvas, 1851-1852, oil on canvas, 30”x44” (at the Tate Britain in London)
For those who are keeping track, that's a body count of three (although I guess there's no actual Goliath body in the Caravaggio one, is there? So maybe that one doesn't count...?).
Boy, I was a weird kid.
