killing monks in a great medieval abbey famed for its library - and why? Brother William of Baskerville is sent to find out, taking with him the assistant who later tells the tale of his investigations. Eco's celebrated story combines elements of detective fiction, metaphysical thriller, post-modernist puzzle and historical novel in one of the few twentieth-century books which can be described as genuinely unique.
Set in Italy in the Middle Ages, this is not only a narrative of a murder investigation in a monastery in 1327, but also a chronicle of the 14th century religious wars, a history of monastic orders, and a compendium of heretical movements.
