"This study presents sixty-three frames selected from the Palatine Gallery, the Uffizi Gallery, the Museo degli Argenti and Villa Poggio a Caniano which are considered of interest from the historic, artistic and documentary point of view. These frames were all commissioned by members of the Medici family, often for paintings of an earlier period, such as those for the 16th-century Venetian paintings, ordered by Giovan Carlo and Leopoldo de' Medici in the 17th century."--Preface, p.
