The Subiaco _De Oratore_ is a large quarto of 109 leaves, with thirty lines to the page. Like the first German books, it is beautifully printed, and shows few signs of being an early production. Sweynheym and Pannartz must have learnt their business carefully, for this their first book is printed by half sheets, _i.e._ two pages at a time, though other printers were still printing their quartos page by page. On the 29th October 1465 these printers issued their first dated book, the first edition of Lactantius _De divinis institutionibus_. Of this book 275 copies were printed. It is a small folio of 188 leaves, and thirty-six lines to the page, printed in a type which, though Roman, is very Gothic in appearance, and is sometimes called semi-Gothic. The smaller letters have a curious resemblance to those used by Zainer at Ulm and by Schussler at Augsburg in their earliest books, though the capital letters are quite different. The fourth and last book printed by Sweynheym and Pannartz at Subiaco was an edition of the _De civitate dei_ of Saint Augustine. This is a large folio, of 270 leaves, with two columns, and forty-four lines to the page. It was issued on the 12th June 1467; and though it contains no name of either printer or place, can be easily identified by the type. A copy in the Bibliothèque Nationale has an extremely interesting manuscript note, which tells us that Leonardus Dathus, ‘Episcopus Massanus,’ bought the book from the Germans themselves, living at Rome, who were producing innumerable books of that sort by means of printing, not writing, in November 1467, This note is valuable in two ways; it puts it beyond doubt who the printers of the book were, and it also enables us to determine more precisely the date when they left Subiaco. The _Augustine_ was finished in June, and by November the printers were at Rome. As they issued a book in Rome in 1467, and would take some time to settle in their new establishment and prepare their new types, we may take it as probable that they left the Monastery of Subiaco as soon as possible after the printing of the _Augustine_. About June, then, Sweynheym and Pannartz left the Monastery of Subiaco and transferred their printing materials to Rome, finding a home in a house belonging to the brothers Peter and Francis de Maximis. The semi-Gothic fount of type which had been used at Subiaco was discarded in favour of one more Roman in character, though heavily cut and not so graceful as the Venetian of the same period. A curious appearance is given to it by the invariable use of the long s. Their first venture was again a work of Cicero, the _Epistolæ ad familiares_, a large quarto of thirty-one lines to the page. It has the following colophon:— ‘Hoc Conradus opus Suueynheym ordine miro Arnoldusque simul pannarts una aede colendi Gente theotonica: romæ expediere sodales. In domo Petri de Maximo. M.CCCC.LXVII.’
