'Premierk Edition de cette version, et un des plus anciens livres imprimis oii se trouvent des figures de math^- 

 m&tiquea'.— Brunei. In his dedication the printer says that the difficulty of printing geometrical designs had hitherto 

 made it impossible to print geometrical books ; but that this difficulty had been overcome so well by great painters, that 

 'qua facilitate litterarum elementa imprimuntur ea etiam geometrice tigure conHcerentur'. The fine woodcut border 

 surrounding p. 3 is a well-known example in the history of book ornamentation. 



The translation is of great interest as having been made by an Englishman, iETHELHARD or Adelard of Bath, either 

 from the Greek original, or, more probably, from an Arabic version. ^Ethelhard was a great traveller as well as one of the 

 greatest philosophical writers of the Thirteenth Century, ' and seems to have passed through Spain, the North of Africa, 

 Greece, and Asia Minor. He was one of those Englishmen who lived for a time in the Norman Kingdom of Sicily, and is 

 known to have visited Syracuse and Salerno. That he knew Greek is almost certain ; but it has not been determined 

 whether the translation of Euclid (undoubtedly executed by him, though olten ascribed to Campanus of Novara, with 

 whose comments it was published at Venice in 1482 [supra]) was made from an Arabic version or from the original ' 

 (Professor Adamson). On either supposition the instance of English mediaeval scholarship is a striking one, and ^Ethelhard 

 is one more disproof of the theory of the blank ignorance and obscurantism of the Middle Ages with which the youth of 

 England is still regaled by the timberheaded textbook-writer of British popular Protestantism.

[col. .] Venetiis, Paganinus de Paganinis de Brixia, 1509 

 The rarest of all the editions of Euclid, and moreover a beautiful specimen of early typography. 

 'This is perhaps the scarcest of all the editions of Euclid, as is but too well known to mathematicians, who covet its 

 possession. The version attributed to Campanus, but now known to have been made by Adelard of Bath, appears here 

 to great advantage, owing to the important emendations and explanations of the celebrated Luca Pacioli di Burgo, the 

 &ni'hor oi the Summa dt Arithvietica [v. Nos. 3428-32, ante']. Pacioli was the intimate friend of Leonardo da Vinci, at 

 whose instigation he appears to have published this work, as is apparent from the dedicatory letter of the editor himself 

 to Francesco Soderini, Cardinal de Volterra, to whom, as well for his own favour as for the patronage of the great 

 Florentine family of which the prelata was a member, he gratefully renders acknowledgment '.—Libri Catalogue.
