| Editio Princeps: | The first edition of the de Officiis was from the press of Sweynheim and Pannartz at the Monastery of Subiaco; possibly the edition published by Fust and SchÖffer at Mainz is a little older. Both appeared in 1465. The latter was the first to print the Greek words in Greek type. The de Officiis is, therefore, the first classical book to be issued from a printing press, with the possible exception of Lactantius and Cicero's de Oratore which bear the more exact date of October 30, 1465, and were likewise issued from the Monastery press at Subiaco. |
