The picture they left was not a rose. It took me a moment to recognise it: the distended jaws of a beast wrapped around naked fleeing souls, the flames of hell around them and the red robes of the Risen Christ. Each of the figures was picked out in black thread but for Christ, from whom gold thread radiated. Their faces all had that doe-eyed squint so common in medieval illumination, especially the beast of hell who but for its teeth and flaming jaw had an almost cute air.
