Zustand: Good. in-8, 14 cc. nn. con alcune illustrazioni xilografiche nel testo. Cartonato posteriore. Ogni pagina riporta le tabelle astronomiche dei mesi dell'anno 1538, ognuna ornata di finalino xilografico e con le posizioni dei pianeti giorno per giorno.  La presente Effemeride è tratta dalla prima edizione della raccolta : "Ephemerides recognitae et ad vnguem castigatæ per Lucam Gauricum Neapolit. [Venezia] : [Lucantonio Giunta 1.], 1533 (In florentissima vrbe Veneta : sumptibus Luc?ntonij Iuntæ typographi, 1533)".  Non comune.  Prima edizione di queste effemeridi, contenenti tavole e previsioni astrologiche per l'anno 1538, attribuite all'astronomo-raccoglitore di dati astrologici e matematico Luca Gaurico (1474-1558) .L'astronomo fu nominato ?consulente astrologico? di Caterina de' Medici dopo aver previsto correttamente, all'età di quattordici anni, l'ascesa al papato del prozio di Caterina, Giovanni de Medici. Divenne famoso in tutta Europa per aver previsto, nel 1529 e nel 1532, l'ascesa al soglio pontificio di Alessandro Farnese.  Come matematico, Gaurico è noto soprattutto per la prima traduzione in latino delle opere di Archimede "De Mensura Circuli" e "De Quadratura Parabolae" (1503). Esemplare di grande freschezza.  . Book.

First Edition. 4to, ff.32; small woodcut Sessa device on title-page and different device below colophon, title with woodcut illustration of Archimedes standing on a map and looking up at the heavens, woodcut initials and diagrams; title-page slightly dust-soiled with small repair at foot, title tipped in and (conjoint) leaf a4 strengthened along gutter, a few headlines shaved, occasional light spotting, final verso with slight offsetting; a good copy in nineteenth-century boards, green morocco spine label, year of publication lettered to upper cover in manuscript, remains of index tabs; binding a little soiled; bookplate of 'Progel' (probably Joseph Bonaventura Progel, of Munich, d.1851).The first appearance in print of any complete work by Archimedes, 'generally regarded as one of the greatest mathematicians the world has ever known' (PMM), including one of the earliest approximations of the value of p. This work contains Archimedes' mathematical treatises Quadratura circuli and Quadratura parabolae, in the Latin translation of William of Moerbeke, which accompanied similar works on the quadrature of the circle by Campano da Novara and Boethius. In Quadratura circuli, Archimedes 'calculated the ratio of circumference to diameter (not called p until early modern times) as being less than 3-1/7 and greater than 3-10/71. In the course of this proof Archimedes showed that he had an accurate measurement of approximating the roots of large numbers' (DSBI, p.222). Quadratura parabola proved that the area enclosed by a straight line and a parabola is equal to 4/3 the area of a triangle with equal height and base. 'Archimedes demonstrated the quadrature of the parabola by purely geometric methods. In the first part of the tract he demonstrated the same thing by means of a balancing method. By the use of the law of the lever and a knowledge of the centers of gravity of triangles and trapezia, coupled with a reductio procedure, the quadrature is demonstrated' (ibid., p.219). Tetragonismus represents the earliest appearance of any work by Archimedes in Latin, predated only by excerpts in Valla's Deexpetendis et fugiendis rebus opus (Venice, 1501). The first printing of Archimedes in Greek was not until 1544, accompanied by Regiomontanus's version of the Latin text. These publications, along with Tartaglia's reprint of these two Archimedean texts in 1543, facilitated the use of Archimedes by Galileo, Torricelli, and Kepler.

Soft cover. Zustand: Very Good. 1st Edition. FIRST EDITION. 4to, 324 unnumbered leaves. Roman letter, printer's device to t-p and last. Detailed woodcut astronomical tables comprising almost the entire volume (ephemerides, all with charming woodcut ornamental motif at foot), horoscope diagrams, wind diagrams, birth charts and illustrations of lunar phases. Light marginal fingersoiling, small waterstain to lower margin of a few initial gatherings at gutter, slight foxing or yellowing to a couple of ll. A very good copy in contemporary limp vellum, a bit worn, couple of small holes in lower cover, spine a bit cracked with contemporary ms. title, yapp edges, traces of ties, a.e. blue (faded), C15 manuscript stubs from 'Expositio Fratrum Regulae Fratrum Minorum". Frequent contemporary Italian marginalia; contemporary ms. annotations to t-p: ex libris "Franciscus Bencius et Amicorum", dates and times ("1511 ott[obre] ore 7 dinotte"), zodiac simbols; to verso of last: "Ampusa, amfusa, amchlusa / anpusa, anfusa, anchlusa", 6-line ms. instructions on how to remove ink from paper using salt, water and the juice of a bitter orange (part of the second line appears to have been almost successfully cancelled), "Gio Boni naquit in Firenze addi 19 giugnio 1495 aore dua dinotte". Three loosely inserted early papers containing sketch of an ephemeris birth chart, ms. letter from Sylvestro Iacobello to Franciscus Bencius, incomplete letter (first half missing, early C16) in a different secretary hand. Attractive copy of the first edition of Gaurico's ephemerides. Books of this kind had wide circulation, but complete copies are rare and sought after. This one, with interesting contemporary annotations and loosely inserted papers of an early owner, is an outstanding witness of the 16 th century's great interest and expertise in astrology. Luca Gaurico (1475-1558) was the astrological consultant of Caterina de' Medici and "one of the greatest astrologers of all time" (Cantamessa). Born to a to a poor family of Gauro (Kingdom of Naples), Gaurico taught at the Universities of Bologna and Ferrara. He was exiled and tortured by the ruler of Bologna, Giovanni II Bentivoglio, dissatisfied with the astrologer's prophecies about his destiny. Gaurico predicted the papacy of Alessandro Farnese, Pope Paul III, who welcomed him in Rome as his personal astrologer and made him "table companion", knight and later bishop. 'Ephemerides recognitae' contains the ephemerides for the years 1534-1551. These are detailed tables listing the predicted positions of stars and planets at regular intervals of date and time in the future, as well as the occurrence of eclipses. The numerical data was used by astrologers to compile birth charts (like the one sketched in ink on a loosely inserted piece of paper) and formulate predictions. Similar tables were also used by navigators to determine their position using celestial bodies or stars. An initial section contains preliminary notions of astronomy and mathematics, including tables of longitude and latitude of various cities, two large diagrams of the winds and more horoscope examples. At the half of the 16th century, this volume belonged to "Francesco Benci and his friends". From the contemporary manuscript notes, it appears that these included high-profile individuals from Perugia, Foligno and Camerino (Umbria, Italy). He can be identified with the Florentine Francesco Benci, treasurer of Perugia in 1542. Benci himself, and possibly some of his friends, used the ephemeris tables in this volume as if they were calendars, annotating all sorts of important events in the blank margins. These include religious festivities, the conclave in 1549, the birth of the twins of Margaret of Parma and Ottavio Farnese (dukes of Camerino) in 1545, a meeting between Pope Paul III and Holy Roman Emperor Charles V in 1543.
