Exhibition of the week
Strange Beauty: Masters of the German Renaissance
The 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.
