"In 1688 Ozanam provided an ample explanation of the use of the proportional compass which Galileo Galilei 1564-1642 had illustrated in his work "Operations of the geometric and military compass" dated 1606. This instrument. . . was intended to provide a quick means of calculation for all operations pertaining to the art of war such as ballistics or the measuring or distances and of places. / Ozanam's text . . . is divided into two parts. The first regards the construction and use of the sector that versatile Galilean instrument of 1596. The second consists in a treatise on the division of surfaces." – Cigola p. 229. / "By almost any criterion Ozanam cannot be regarded as a first rate mathematician even of his own time. But he had a flair for writing and during his career wrote a number of books some of which were very popular passing through many editions. . . . In short his contributions consisted of popular treatises and reference works on 'useful and practical mathematics'" –William L. Schaaf DSB X p. 264. PROVENANCE: Stonor family; A. H.
