The 1651 edition of Trattato, written by Leonardo, has broadly been investigated as regards its genesis and preparation, while still to show in an appropiate way it its reception in the historiography and artistic literature of the second half of the century.

The research campaign currently underway by the proponent and the group of young students who support him, demonstrates how the volume has immediately become a fundamental work tool for historiographers and art theorists active in different Italian contexts (Scannelli, Scaramuccia, Alveri, Bellori, Passeri, Padre Resta, Giuseppe Ghezzi…), deeply influencing their critical orientations and stimulating in turn the interest in Leonardo’s work. As regards the Roman context, it has resulted in more or less founded attributions for drawings and paintings preserved in great princely and cardinal collections, but also important recoveries of materials, for example the case of the Leicester code found at the heirs of Guglielmo Della Porta and at the center of the correspondence between Padre Resta and his friend Ghezzi. From the analysis of these and other voices, more or less famous, emerges with ever greater clarity who was the seventeenth-century Leonardo, which today appears to us, even in the corpus of the works ascribed to him, so different from ours.

The workshop is scheduled for November 2019, will be held in Rome at Palazzo Braschi.
