Isidoro Cioffi, Physica democritica seu atomorum sapientia, a survey of physics and natural history pertaining to celestial bodies, manuscript in Latin, on paper [Italy (Naples), various parts dated 2 March and 28 April 1718] 140 leaves, complete, single column, c. 30 lines in a somewhat scrawling hand, titles in capitals, diagrams of mathematical shapes (fol. 44v-45r and 78v-78r), the atom (fol. 75r), Ptolomy s order of the layers of the universe (fol. 100r), the same of Copernicus (fol. 100v) and of Tycho Brahe (fol.101r), an experiment to demonstrate the uses of mercury (fol. 110v), an eclipse (fol. 142r), another experiment showing the expansion of gases under heat (fol. 126v), the winds (fol. 127v), the orbit of the moon (fol. 132v), and an experiment in a section titled De aquarum mirabilis , stains, edges bumped and first leaf detached, else good condition, 200 by 145mm., card binding (now battered, torn away at spine and becoming loose) The author was perhaps an Augustinian. Despite producing a scientific compendium, drawing together the works of Ptolemy, Copernicus and Tycho Brahe, he dates the end of each major section and dedicates it to God and various saints, including conspicuously Augustinian ones, such as SS. Augustine, his mother Monica, and Nicholas of Tolentino (Augustinian Friar, d. 1305). A further saint commemorated in this way may reveal Jesuit leanings or experience in the Far East on missions. On fol. 79v, the author ends his dedication colophon with the Spanish saint, Francis Xavier (1506-52), one of the co-founders of the Jesuits who spent his life in missions in the Far East in the Portuguese Empire there.
