To single out details from the great dream of Roman churches, would be the wildest occupation in the world. But S. Stefano Rotondo, a damp, mildewed vault of an old church in the outskirts of Rome, will always struggle uppermost in my mind, by reason of the hideous paintings with which its walls are covered. These represent the martyrdoms of saints and early Christians; and such a panorama of horror and butchery no man could imagine in his sleep, though he were to eat a whole pig raw, for supper. Grey-bearded men being boiled, fried, grilled, crimped, singed, eaten by wild beasts, worried by dogs, buried alive, torn asunder by horses, chopped up small with hatchets: women having their breasts torn with iron pinchers, their tongues cut out, their ears screwed off, their jaws broken, their bodies stretched upon the rack, or skinned upon the stake, or crackled up and melted in the fire: these are among the mildest subjects.
