Romancier, journaliste, érudit et bibliophile, Paul Lacroix alias le bibliophile Jacob (1806-1884) traverse le XIXe siècle à l’aune d’une trajectoire qui oscille entre écrivain-journaliste et conservateur de la bibliothèque de l’Arsenal à partir de 1855. À la faveur du double mouvement de reconfiguration de l’historiographie et du champ littéraire, dont il est un acteur au croisement des obsessions du temps entretenues par le romantisme, son oeuvre imposante et protéiforme tente une réunion des plumes de l’historien et du romancier soutenue par l’énigmatique et habile pseudonyme, gage de son succès en 1830. Il s’empare sous la monarchie de Juillet d’une écriture du passé vouée à en dresser l’inventaire, soumise aux modalités fluctuantes offertes par le récit comme aux injonctions économiques dépendantes des mutations de la librairie et du journal. Si sa production se défend de tout esprit de système, résumée par la course à la fabrication d’un grand « roman-histoire », elle interroge pourtant les conditions de définition d’un rapport au temps ébranlé après la Révolution. Le « Walter Scott français » sacrifie à la vogue du Moyen Âge pour la décliner sous la forme d’une histoire autant héritièrede l’érudition antiquaire qu’elle participe de la fondation d’un récit des origines tributaire d’une écriture spéculaire de l’histoire. Son histoire s’égrène au rythme de médaillons romancés cristallisant couleurs, intrigues, travers des temps médiévaux et modernes séparés par une frontière poreuse qui interroge les conséquences de la rupture révolutionnaire. Avers et revers de ces médaillons posent dans leur alternance les jalons d’une expérience de mise en ordre du temps. / A novelist, writer, scholar and book-lover, Paul Lacroix, aka bibliophile Jacob (1806-1884), went through the nineteenth century as both a writer-journalist and a librarian at the Bibliothèque de l’Arsenal from 1855 on. Influenced by the deep changes affecting both historiography and literature, in which in actively participated and the obsessions of its times nurtured by the romantic movement, his abundant and multifaceted work tried to melt the historian’s and the novelist’s approaches, materialised by the mysterious, clever pen name, the token of his success in 1830. Under the July Monarchy, he undertook to take an inventory of the French historical past; his writings were submitted to the fluctuating possible modalities provided by the narrative as well as the economic imperatives resulting from the transformations of bookshops and libraries. Though his works did not try to set up a closed and coherent system, which was illustrated by the race for the ultimate roman-histoire, they questioned French people’s relationship with time, which was seriously undermined by the Revolution. The so-called « French Walter Scott » followed the taste for the Middle-Ages and wrote historical novels thatreminded one of the specialists of the Antiquity and contributed to founding a narrative of the origins based on a speculative approach of history. His historical narratives is pervaded with fictionalised cameos crystallising the colours, plots and pitfall of both medieval and modern times, separated by a porous border, thus questioning the consequences of the French Revolution. The two faces of those cameos paved the way for a rearrangement of historical time/events.

The theoretical part focuses on the theme of the book - letter print - from the technical point of view. Further it explores the history, origin and various forms of a book. The thesis includes also chapters about a copyright book and the term " bibliophile". It also gives brief information about the graphic art, especially the technique of gravure. In the last part it aims at two personalities of Czech culture - a painter and graphic artist Jiří John and Jan Skácel. The practical part of the thesis is conceived as a folder that includes series of graphics accompanied with poetic texts. The graphic works are made by dry needle. The texts are written by Jan Skácel. The topic of the the copyright book expresses the author´s memories of her grandmother. The topics of each graphic work depicts the psychology of the contrast between the oldness and the youth and at the same time of the loss of a close person. The practical part should be also a sort of bibliophile.

La tesi delinea la figura di Gian Giacomo Trivulzio (Milano, 1774-1831), bibliofilo, editore, intellettuale. La prima parte è dedicata a una ricostruzione sistematica della biografia, la seconda si concentra sui principali interessi culturali di Trivulzio, in particolare: l’amore per Parini, la produzione poetica originale (con una breve storia dell’Accademia degli Inesperti), l’attività collezionistico-editoriale legata ai novellieri italiani, gli studi critici e testuali condotti o promossi su una parte dell’opera di Boccaccio. Infine, il progetto di un’antologia della poesia italiana dalle origini a Poliziano e le proposte di emendazione del Convivio, della Vita nuova e delle Rime di Dante testimoniano gli sviluppi più maturi di quella che si può a buon diritto definire filologia trivulziana. / The thesis is about Gian Giacomo Trivulzio (Milan, 1774-1831), bibliophile, editor and intellectual. The first part is a Trivulzio’s systematic biography, the second one focuses on his main cultural interests, particularly: his love for Parini, his original poetic production (with a short history of the “Accademia degli Inesperti”), his collectible and editorial activity linked to the Italian novelists, his critical and textual studies on Boccaccio’s works. Finally, the project concerning an anthology of the Italian poetry from its beginning to Poliziano and the proposals for a recovery of Dante’s Convivio, Vita nuova and Rime textify the most mature developments of what can rightly be defined Trivulziana philology.

The aim of this diploma thesis is to introduce the phenomenon of rare books and artist's book, their place in the domestic book production and the subjects that deal with their creation and publishing. In addition to publishing houses, also associations are introduced in the thesis, including universities, where numerous projects devoted to the artist's book are created. The current situation of rare books and artist's books is also reflected through exhibitions, competitions or fairs that focus on this topic. Reports on rare books and artist's books in the media provide feedback on how society is aware of and informed about this type of book production and how the society perceives it.
