This is the catalogue of an exhibition held at the Museum of Archeology and Art in Grosseto, Italy, from May to September 2008 in which thirty-one masterpieces of sixteenth-century Tuscan art were displayed for the public, most for the first time. Precise reproductions, both complete and in detail, are accompanied by rigorous academic and philological critical essays. The catalogue provides the reader with a striking pictorial treasure of rare beauty, while also appealing to scholars and experts through the quality of so many previously unpublished works by over twenty famous artists from the period.
