‘Magister vero Conradus Sweynheym, Germanus, a quo formandorum Romæ librorum ars primum profecta est, occasione hinc sumpta posteritati consulens animum primum ad hanc doctrinam capescendam applicuit. Subinde mathematicis adhibitis viris quemadmodum tabulis eneis imprimerentur edocuit, triennioque in hac cura consumpto diem obiit. In cujus vigilarum laborumque partem non inferiori ingenio ac studio Arnoldus Buckinck e Germania vir apprime eruditus ad imperfectum opus succedens, ne Domitii Conradique obitu eorum vigilæ emendationesque sine testimonio perirent neve virorum eruditorum censuram fugerent immensæ subtilitatis machinimenta, examussim ad unum perfecit.’ The book contains twenty-seven maps, each map being printed on two separate leaves facing each other, and printed only on one side. The letters which occur on the maps in the names of places are evidently punched from single dies, and not cut on the plate, as would have been expected. The letterpress of the book is not printed in any type used by Sweynheym or Pannartz, which shows that Buckinck was the absolute printer of the book. Ulric Hahn, who contests with Sweynheym and Pannartz for the honour of having introduced printing into Rome, issued as his first book, in 1467, the _Meditations_ of Cardinal Torquemada, better known perhaps as Turrecremata. It is illustrated with thirty-three woodcuts of inferior execution, and is printed in a large Gothic type. This type the printer discarded the following year for one of Roman letter; but odd types from the Gothic fount frequently make their appearance among the Roman, and serve as a means of distinguishing Hahn’s books from others in similar Roman type. As a case in point, we may mention the early and probably first edition of _Catullus_, wrongly ascribed to Andrea Belfortis of Ferrara and other printers. This book is in Hahn’s Roman type, and contains three capital letters from his Gothic fount;—a more sure means of identification than a fancied allusion to a printer’s name.[17] For a short time, from 1470 to 1472, Hahn’s books were edited by Campanus, a scholar of such fame and erudition, that the printer was able to rival Sweynheym and Pannartz, with their editor the Bishop of Aleria; but on Campanus taking his departure for Ratisbon, the prestige of Hahn’s press declined. From the pen of Campanus came perhaps the punning colophons which play upon the name of Hahn, in Latin, Gallus, meaning in English a cock. Upon the departure of Campanus, Hahn, took in partnership one Simon Nicolai Chardella of Lucca, who seems to have supplied the money as well as superintended the publishing, and they continued to work together till 1474. From this date till 1478, Hahn continued to work alone, ending in that year as he had begun, with an edition of the _Meditationes_ of Torquemada. His former partner, Simon Nicolai, started a press on his own account, having as an associate his cousin.
