The Jigoku-zoshi (â€œHell Scrollsâ€ ) and similar documents from the 12th century onwards are amongst the earliest, and bloodiest, accounts of human carnage in Japanese art. Victims are burned, drowned in blood and excrement, crushed by fiery rocks, flayed, eaten alive by beasts, and have their bones pulverised by vicious, club-wielding oni (horned, clawed, fanged demons who may have multiple eyes and blue or red skin). This is the Buddhist concept of purgatory, where sinners have eight â€œgreat hellsâ€ and sixteen â€œlesser hellsâ€ to contend with. Japanese Hell pictures comprise a startling visual catalogue of atrocity and suffering. TORTUREâ€DEMONS presents more than 60 such images, shown in full colour throughout, in which sinners are subjected to multiple mutilations and dismemberments, an orgy of religious retribution, torment and putrefaction.
