Una pagina inedita degli «Scrittori d’italia» del Mazzuchelli: la biografia dell’umanista bresciano Ubertino Posculo

«Scrittori d’Italia» [Italian Writers] by Giammaria Mazzucchelli (Brescia, 1707-65) is a mammoth encyclopaedic dictionary intended by the author to include the biographies of all those writers active in Italy from the mediaeval period to his own time, with each entry including a description of the author’s works and a detailed bibliography. Mazzuccchelli’s endeavour remains for the most part unpublished in a series of manuscripts housed at the Vatican Library. This article offers a transcription of the entry present in Vat. Lat. 9283 dedicated to Ubertino Posculo, a humanist from Brescia, the first edition of which serves as part of a more extensive study on this figure.
