The Klesch portrait by Titian of Guidobaldo II with his son Francesco Maria represents the duke of Urbino in his full power as supreme commander of papal troops, with his heir next to him. This rare, full-length double portrait has only recently been attributed to Titian after undergoing extensive analyses and restoration, revealing a beautiful painting in non finito manner, with bravura impasto passages entirely characteristic of the master, all of which is illustrated and explained in this new book.00In this volume full of new research, Ian Verstegen reveals that Guidobaldo was not peripheral but central to Italian politics and was regarded at several points in history as a key figure who could bring peace or who could influence major conflicts on the Italian peninsula, particularly the War of Siena, and then Pope Paul IV's offensive war against Spain. Anne-Marie Eze gives the first comprehensive examination of the painting's provenance, outlining the portrait's vicissitudes and reception at different moments in its near 500-year history, reexamining received wisdom and fill gaps in our knowledge of its whereabouts. Finally, Matthew Hayes and Ian Kennem about its past ownership, and presenting new documentary evidence to expand on dy reflect on the technique, date, recent conservation, and authorship of the painting, proving it to be a masterpiece that only the great Titian could have created.
