' He is doubtless the greatest geometer of the XVI. century. From the notes of Pappus he attempted to restore the 

 missing fifth book of Apollonius on. maxima and minima. His chief work is his masterly and original treatment of the 

 conic sections, wherein he discusses tangents and asymptotes more fully than Apollonius had done, and applies them to 

 various physical and astronomical problems.' Prof. Cajori. 



Vol. I contains : De Sphsera liber unus : Computus Ecclesiasticus in summam rollectus : Tractatus Instrumentorum 

 Astronomicorum : Tractatus de Lineis Horariis : Euclidis Propositiones Elementorum, etc.: Musicse Traditiones: De 

 Lineis Horariis libri III ; and vol. II : Arithmeticorum Libri II. 



'All the works of this eminent mathematician are of considerable rarity. His treatise on the properties of numbers, 

 and on the doctrine of incommensurables is a very superior production to that of any of his contemporaries.' Libri 

 Catalogue. Opera rara ed apprezzata.' Riccardi. 



'On trouve souventd'hemeuses innovations dans les nombreux ouvrages de Maurolico ; telle est encore cetteremarque, 

 qui fut entre ses mains la base de nouveaux principes de gnomonique, que 1'ombre de 1'extremite d'un style decrit chaque 

 jourun arc de section coniqne. C'est a cette occasion qu'il compsa son Traite dex Coniqnes, qui fait le sujet du 3 livre de 

 sa gnomonique, intitulee De lineis horariis libri III, et imprimee dans ses Opu.scu.la Mathematica. Maurolico y fait deriver 

 les proprietes des coniques de celles du cercle et de la consideration du solide dans lequel ses courbes prennent naissaiice. 

 . . . L'analyse est aussi tres-redevable a Maurolico : c'est lui qui le premier introduisit 1' usage des lettres, a la place des 

 nombres, dans les calculs d'arithrnetique, et qui donna les premieres regies de l'algorithme de 1'algebre.' E. Merlienr.

 by Christoph Clavius, s j. 



The work is important in the history of optics, and the first to call attention to the curves afterwards called caustics. 

 The author also correctly describes the crystalline lens of the human eye, and based on it gives a physical explanation of 

 myopia and hypermetropia. 



A full account of this rare work will be found in Wilde's Gcschichte der Optik, pp. 126-134.
