Details 434 came from Luca Signorelli's The Damned, part of his spectacular fresco cycle in Orvieto Cathedral (painted 1499-1504), which illustrates the end of the world. This scene - devils duffing up the souls of the lost - works like a 3-D Jackson Pollock. It's a drama of containment. As in a Pollock - where the swarming, fermenting paintwork often stops at a margin, fizzing, just short of the painting's edges - the main force of Signorelli's image comes from the way the frenzy of bodily energies is packed, a tableau held within the picture's ground, an enormous torment-scrum struggling (it seems) against the bounds of a marked pitch.
