La thèse est consacrée à l’œuvre de portraitiste de Parmigianino au cours des deux périodes parmesanes de sa carrière, depuis sa naissance en 1503 jusqu’à son départ pour Rome en 1524, puis de 1531 à 1540, date de son décès. L’objet de la recherche est d’élucider les significations propres à chacune des effigies du corpus et d’analyser les processus plastiques et sémantiques par lesquels le peintre a élaboré les discours figuratifs que constituent ses portraits, dans le contexte de leur commande, production et réception. A cette fin, on a opté pour une approche pluridisciplinaire. La thèse débute par une étude de l’histoire artistique de Parme de 1500 à 1540 et une analyse des pratiques du portrait dans cette ville, au regard de ses nombreuses relations avec d’autres centres culturels et artistiques (Milan, Venise, Bologne, Florence et Rome). L’histoire sociale et politique de Parme pendant la première moitié du Cinquecento est un autre sujet de la recherche. Son objet est l’articulation des transformations institutionnelles au sein de la comune, les conquêtes par plusieurs pouvoirs étrangers entre 1499 et 1520 jusqu’à la création du duché de Parme et Piacenza par Paul III en 1545 avec le marché et les pratiques du portrait. Après cette étude du contexte, chacun des portraits de Parmigianino est examiné de façon approfondie, à travers une approche trans-disciplinaire qui associe histoire de l’art, histoire culturelle (littérature, du livre et de l’édition, emblématique, traditions de la rhétorique, débats linguistiques), histoire sociale et politique. / The dissertation deals with Parmigianino’s activity as a portraitist during the two periods of time he spent in his native Parma, between 1503 and 1524 and then between 1531 and 1540. Its aim is to analyze the painter’s male portraits in particular, that is to to clarify their specific significances and, at the same time, to elucidate the visual and semantic processes through which Parmigianino elaborated the figurative discourses that his portraits convey, in the artistic, cultural, social and political context of their creation. To reach this goal, several methodological approaches are used. The disseration begins with a close study of the artistic history of Parma between 1500 and 1540 and an analysis of the traditions related to portraiture in the city, with regard to its many cultural and political relations to other regions and states (Milan, Venice, Bologna, Florence and Rome). The political history of Parma during the first half of the Cinquencento is an other field of research. Its purpose is to articulate the many institutionnal transformations of the comune, the conquest of Parma by several foreign powers between 1499 and 1520, until the creation of the Duchy of Parma and Piacenza by Pope Paul III, with the market and practices of portraiture. After this close examination of the context, Parmigianino’s portraits are analyzed through a trans-disciplinary approach that deals with art history, cultural history (literature, history of the book, emblems, traditions of rethoric, linguistic debates), social and political history).

The Sack of Rome of 1527 was the greatest disruption to the history of sixteenth-century Italian art. Sufficient attention has been paid to its ramifications in terms of the diaspora of artists from Rome that disseminated "Mannerism" throughout Europe and monumental papal projects executed in its wake, including Michelangelo's Last Judgment (1534-41), Perino del Vaga's decoration of the Sala Paolina in Castel Sant'Angelo (1545-47), and the propagation of a more disciplined use of classicism in architecture and literature by the papacy of Pope Paul III. Focus on these consequences, of a grand scale, emphasizes the impact of the event for papal history but has obscured to some extent a set of works that was directly and immediately affected by the Sack of Rome: paintings by artists who were dispersed from Rome, produced in cities of exile. These paintings by displaced artists are the subject of my dissertation. Repercussions of the Sack disrupted the practice of painters who were forced to flee the ruined city, including Polidoro da Caravaggio, Perino del Vaga, Giovanni da Udine, Giovanni Antonio Lappoli, Vincenzo Tamagni, Parmigianino, Rosso Fiorentino, and Sebastiano del Piombo. The first post-Sack paintings of three of these artists, executed for private patrons (rather than under papal or imperial direction as in the cases of Giovanni da Udine and Perino), signal the disruption of the Sack through both marked stylistic innovation and iconographic manipulation: Parmigianino's St. Roch with a Donor in Bologna, Rosso's Lamentation at the Foot of the Cross in Sansepolcro, and Sebastiano del Piombo's Nativity of the Virgin in Rome. In these altarpieces, each artist exhibits a distinct change in his creative production and disturbs the iconography of a well-established sacred subject by inserting an aberrant and conspicuous reference to Rome. Together, these examples suggest that, while the artists do not illustrate the event of the Sack itself in their works, they mark their paintings as products of a specifically post-Sack context, in which the identity of the three painters as refugees from Rome was an essential component. This study raises the problem of the roles of historical trauma and of biography in art historical investigation. Chapter One examines contemporary writings about artists and the Sack and explores the extent to which an artist's association with the event was both a deeply personal issue as well as a public aspect of identity. The cases of Polidoro, Lappoli, and Tamagni are presented here as complementary cases to the chapter studies of Parmigianino, Rosso, and Sebastiano. Chapter Two investigates Parmigianino's production of the St. Roch altarpiece in Bologna, where his new monumentality and dramatic effect combine with an incongruous inclusion of antique costume to assert his artistic lineage to and recent departure from Rome. Chapter Three studies Rosso in Sansepolcro and the ways in which his Lamentation signals his distance from Rome - both physical and artistic - through appropriation of local culture and through his inversion of the figure of the Roman soldier. Chapter Four follows Sebastiano back to Rome after exile where he resumed the project for the Nativity that had been interrupted by the Sack. His emulation of the art of his former rival, Raphael, introduces an aberrant classical component that acknowledges at once the nostalgia for pre-Sack Rome inherent in his commission and the transformation, initiated as a result of the Sack, of the legendary site of the Nativity itself, at Loreto.
