Bound in full contemporary vellum, with ink titling to spine. Boards show mild shelf wear and rubbing to vellum.

Shelved in Case 3. The foremost early figure in Jesuit science, Christopher Clavius (1538-1612) was one of the chief architects and defenders of the 1582 calendar reform under Pope Gregory XIII, leading to the modern Gregorian Calendar. Pope Sixtus V said: "Had the Jesuit order produced nothing more than this Clavius, on this account alone the order should be praised". His Euclid Elementorum (Rome, 1589) was brought by Matteo Ricci to China and translated into Chinese. In his Astrolabium (Rome, 1593) he uses a dot to separate whole numbers from decimal fractions and is arguably the first to do so. His Gnomonices (Rome, 1602) contains every then-known principle concerning the measurement of time. Galileo was a frequent visitor to the Jesuit Roman College, and he and Clavius corresponded frequently. 1343886. Shelved Dupont Bookstore. (Inventory #: 1343886)
