Beltramiʹs participation in the Salaʹs re‐discovery in 1893, the architectural and pictorial alterations he ordered in preparing the room for public view, and his monographic presentation of the Salaʹs fifteenth‐century history will be discussed here using new archival evidence. The author will argue that Beltramiʹs interventions ultimately shifted attention away from the Salaʹs fifteenth‐century circumstances and transformed it into a key component of the ambitious restoration scheme that Beltrami had formulated for the Sforza Castle as whole. This was a scheme that supported certain political and cultural ideologies about Milan at the turn of the twentieth‐century. In an effort to provide an alternative voice for the Sala to that of Beltrami, the author will use new archival documentation to discuss the participation of Paul Müller‐Walde, a German art historian who is credited with the actual re‐discovery of the Sala but whose contributions remained curiously absent from all modern art‐historical literature dealing with the Sala. Acting on the v premise that a more plausible and much needed interpretation for the Salaʹs fifteenth‐ century history is needed, the author will offer a reconsideration of some of the Salaʹs most basic problems such as dating, location and possible uses. The author will also deal with Leonardoʹs contributions and the perils of characterizing the Sala as yet another work that sprang fully from Leonardoʹs imagination, with little interference or direction from outside sources. Finally, the author will deal with Ludovico Sforzaʹs reasons for commissioning the Sala and lay the groundwork for an expanded and alternative interpretative discourse intended to broaden the avenue of investigation of this important and unique commission in Renaissance art. This dissertation concludes with an extensive Register of Documents containing reproductions or transcriptions of important fifteenth‐, nineteenth‐ and twentieth‐century documents for the Sala delle Asse. vi If you wish to go to the top of a building you must go up step by step; otherwise it will be impossible that you should reach the top. Thus I say to you, whom nature prompts you to pursue this art, if you wish to have sound knowledge of the forms of objects begin with the details of them, and do not go on to the second [step] till you have the first well fixed in memory and in practice. And if you do otherwise you will throw away your time, or certainly greatly prolong your studies. And remember to acquire diligence rather than rapidity. — Leonardo da Vinci vii TABLE OF CONTENTS LIST OF FIGURES ……..…………………………………………………………………..… xi PREFACE AND ACKNOWLEDGEMENTS ………………………………………………xii 1.

In the company of such works as Raphael’s Villa Farnesina (1511), Giulio Romano’s Palazzo del Te (1527), and Andrea Mantegna’s Camera Picta (1465), the Sala delle Asse presented itself as an anomaly: it was attached to a no‐ less‐famous artist, Leonardo da Vinci, yet only a handful of studies had been published on it. Hopeful and, in retrospect, naive that I would somehow determine the symbolic significance of this complex work in one short semester, I dug as deep as I could into its fifteenth‐century circumstances. When my efforts in iconographic interpretation failed to be fruitful, I shelved the project and returned to my usual scholarly concerns in seventeenth‐century painting and drawing. A year later, John Williams suggested to me that the Sala delle Assemerited additional attention. He had just finished reading Richard Turner’s intriguing book Inventing Leonardo and could see —even before I did— that the Sala could lead to a fascinating Ph.D. topic and new understandings about Leonardo’s role in the history of xii art. I started asking myself the simple question of why the Sala had not enjoyed all of the attention of Leonardo’s other known works. It was in satisfying this curiosity that a dissertation started to take form. I am profoundly grateful to my doctoral committee (Ann Sutherland Harris, David Wilkins, Anne Weis, Kathleen Christian, Francesca Savoia and Dennis Looney) for having faith in me, for offering direction when needed, and for their ample doses of good cheer and friendship. Ann Sutherland Harris showed me the importance of reading works of art with sharpness of mind and eye. It has been a privilege for me to experience the intellectual and artistic richness of Italian art through her teachings. She took me under her wing as a Ph.D. student and taught me —with diligence, affection and much patience— one of the most important lessons in my graduate‐ school training: that critical evaluations are more intimately connected with the historically specific than it is popularly supposed, and that inadequacies in methodology can only be overcome through the disciplined practice of balancing both.
