edited by Giuseppina Florio and Flavia Onofri. For years we had intended to do a work on the printed works of Aldus Manutius. We obviously knew that there were several Aldines in the library, we had catalogued them, inserted them in the Opac SBN, chosen them for exhibitions and educational visits.
The five hundredth anniversary of Aldus’s death in 2015 and our last period of work in the library, prompted us to compile a chronological catalogue of the works he printed and present in 
Casanatense: a tribute to the great humanist typographer who marked the history of printing. Aldus Pius Manutius, (in the first editions we read Aldus Mannuccius, Manucius or Manutius) Italianized as Manuzio, is one of the greatest and most innovative typographers of the second half of the fifteenth century. Suffice it to say that his classical studies aimed not only to preserve Greek and Latin literature from oblivion, but also to spread the texts in printed editions, so much so that he established close relationships with Greek men of letters and scholars, founded the Aldine Academy dedicated to Hellenistic studies and opened the printing house in Venice. Manuzio was always concerned with the quality of his editions, to the point of having his characters, known as Aldine, based on the model of the writing of Greek manuscripts from which the printed books were copied. This is not the time to dwell on the italic character, specially designed by the engraver Francesco Griffo from Bologna and then imitated by all the printers, on the “octavo” volume, lighter and more portable, a smaller format compared to the large “folio” or “quarto” volumes already used by others, but to “browse” the collection preserved in Casanatense. From 1494 to 6 February 1515, the year of his death, Aldo Manuzio printed about 130 editions in Greek, Latin and vernacular.
