Venetiis [c. 1595]' 



An extremely rare and interesting work of which three varieties are known : two having the descriptions only in Latin 

 and Italian, one issue of whih has only 40 plates, and the third as above with the descriptions also in Spanish, French, 

 German, and 49 plates. This issue is the rarest of all. Some of the plates are of great importance, e. g. plate 38 ' Homo 

 volans', giving a perfect representation of a parachute, plates 34-36 suspension bridges, of which no. 34 is the earliest 

 description of one wholly of iron, 49 a diving belt, 41 a digging machine, 43 a rope-making machine, 40 a boat with paddle 

 wheels going up a river, and a great variety of wind, water, and mechanically-driven mills, oil presses, etc. Plate 4 

 represents ' Ecclesia Sibenici ' 



The author, a native of Sebenico, Dalmatia, was Bishop in Partibus of Canadium, in Hungary, and in his later years 

 appears to haved lived in Venice. There is a full description of the work in M. Libri's Histoire des Sciences Mathematiques, 

 where it is termed 'un ouvrage tres rare qui ne se trouve guere indique' par les bibliograph.es.' 



At the end of the descriptions is a List of Machines of the author's own invention, ' fra le quali veramente alcune sono 

 interessantissime ' (Riccardi). 



No copy of this work can be traced as having been sold at auction within the last 30 years.

1 Belle edition '.Brunei. 



In his most important work, In Ai tern, 'the earliest work on symbolic algebra, explaining how algebra could be applied 

 to the solution of geometrical problems', he 'introduced the use of letters for both known and unknown (positive) 

 quantities, a notation for the powers of quantities, and enforced the advantage of working with homogeneous equations 

 . . . One of his improvements was that he denoted the known quantities by the consonants B, C, D, etc., and the unknown 

 quantities by the vowels A, E, I, etc., the other was to introduce new symbols to represent the square, cube, etc. of 

 quantities which had already occurred in the equations . . . These two improvements were almost essential in any 

 further progress in algebra. . . . Vieta's works on geometry are good. He applied algebra and trigonometry to help him 

 in investigating the properties of figures ', etc. etc. etc. W. W. R. Bull.

This work, which treats of the solution of equations, was originally published as an appendix to Vieta's In Artem 

 Analyticam Isagoge. The above edition, which is quite different from that of 1593, has no title, and is numbered from 

 1 to 24, with the signatures A M in twos, and appears to be unknown to bibliographers.
