A sublime volume about one of the most important collections of ancient marble sculptures in the world, an astonishing private trove largely hidden to scholars and the public until now. Last published in a nineteenth-century catalog, the distinguished Torlonia Collection of more than 600 priceless Greek and Roman works--marbles and bronzes, reliefs and sarcophagi, depictions of gods, and portraits of emperors--is one of the most important assemblages of classical sculptures still in private hands anywhere in the world. This eagerly awaited volume presents a selection of nearly 100 sculptures, which have been chosen for their quality and historic significance and which will be featured in an unprecedented exhibition designed by David Chipperfield and held in the Villa Caffarelli, near the Musei Capitolini in Rome, before touring globally. The legendary aura surrounding this, Rome's last princely collection, is due not only to its extraordinary scope and the high quality of the works, but also to the fact that the collection has not been available to the public for decades. This revelatory book features multiple essays by leading experts on the history of the collection and scholarly entries for the works detailing important discoveries made through archaeological research as well as the cleaning and conservation of the sculptures.
