Strange Beauty: Masters of the German RenaissanceThe art of the German Renaissance is full of witches, werewolves and supermodels. Lucas Cranach the Elder painted nudes with a lanky, bony beauty – the Renaissance's answer to heroin chic. He makes Venus look truly sinful. Cranach was Martin Luther's best man, and responsible for burning several supposed witches – so his infatuation with dangerous desire has a dark side. He and his contemporaries mix medieval folklore with the new classical ideas coming out of Italy to create bizarrely compelling masterpieces. This ought to be fascinating.• National Gallery, London WC2N, from 19 February until 11 May.
