Paperback. Condizione: New. Print on Demand. This book, first written in the 13th century and updated over several centuries since, is one of the earliest surviving works of Western science. The author remains unknown. The book is credited with laying the foundation of modern astronomy, promoting the concept of a spherical Earth within a cosmos governed by mathematical laws. The book covers a wide range of topics, including the shape and motion of the Earth, the nature of the celestial sphere, theories of planetary motion, timekeeping, and related subjects. Its insights provide a glimpse into the origins of modern scientific thought and the history of humanity's understanding of the universe.

Christopher Clavius (1537?1612), a German Jesuit and professor of mathematics at the Collegio Romano, was among the leading mathematicians and astronomers of his time. His study and original commentary on the work of Euclid, first printed in 1574, was one of the most influential achievements of Renaissance mathematics, with numerous reprints in the following decades.

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.

An excellent copy. Notes: First published in Rome in 1574, this edition of Euclid's works is annotated by Christophorus Clavius. Clavius ??(1538-1612) came from Bamberg and, following scholarly custom, translated his family name Schlüssel (or Clau) into Latin. He was a mathematician and a Jesuit priest at the Collegio Romano. Called the "Euclid of the 16th century" by his contemporaries, he became famous primarily for the calendar reform to the Gregorian calendar in 1582, which he oversaw. He authored several mathematics books, was interested in astronomy, designed astronomical instruments, established scientific work at the Vatican Observatory, and maintained a friendly relationship with Galileo Galilei. His commentary on Euclid was still being printed at the beginning of the 18th century. - Bibl. Dt. Mus., Libri rari 096; Wellcome I, 2081 (only part 2); Graesse II, 512.

2 parts in 1 volume. Early Latin edition of the Elementorum, one of the most successful textbooks ever written. The present edition contains the complete enunciations of all fifteen books, and the demonstrations, and has been illustrated with hundreds of geometrical woodcut figures. As the foundational text of both geometry and number theory, the work covers plain geometry, proportions, number theory and solid geometry. The present edition has been edited by Christopher Clavius (1536-1612), or "the Euclid of the 16th century" (DSB).Clavius was a German Jesuit mathematician and astronomer, who was instrumental in the Vatican's adoption of the Gregorian calendar, a pioneer of the use of the decimal point, and, in his lifetime, the most highly respected astronomer in Europe. His edition of the Elementorum is his main work. His version is not a translation, but "contains a vast quantity of notes collected from previous commentators and editors, as well as some good criticisms and elucidations of his own. Among other things, Clavius made a new attempt at proving the "postulate of parallels"."(DSB). His edition first appeared in Rome in 1574, and again in 1589. The present edition is the third. There is some confusion in the literature about the place of printing, as the printer, Giovanni Ciotti (1560-1625), mainly worked in Venice, but the present title page mentions Cologne. According to Thomas-Stanford, the work was most likely printed in Venice, but sold by Ciotti's branch in Cologne.With a later manuscript owner's inscription on the front pastedown ("Carl Hollweide, Halle 1802"), the same inscription underneath which has been removed, and an owner's inscription from mathematician Moritz Wilhelm Drobisch (1802-1896) on the recto of the first flyleaf ("M. W. Drobisch. 1824"), all in brown ink. The vellum is somewhat scratched, scuffed, and stained, the corners of the boards are bumped. The vignette has been cut out of the title page, but the hole has been repaired with paper and bears a manuscript note in pencil, the title page and the first blank flyleaf have been reinforced with paper in the lower outer corner, the title page is slightly dust soiled, some occasional stains, a large tear in the bottom margin of leaves G6 in part 1, and Kk4-Kk6 in part 2.

Later blind-tooled overlapping vellum, sewn on 5 supports laced through the joints, with the manuscript author, title, and year of publication on the spine, remnants of closing ties. The title page of each part is set within an elaborate woodcut border, with woodcut decorated initials (at least 3 series), headpieces built up from typographical ornaments, numerous woodcut mathematical figures in the text, large woodcut ornamental tailpieces, and a woodcut printer's device on the otherwise blank verso of the last leaf of both parts.

EDICIÓN. 1611 Edición postuma de Clavius, donde describe los descubrimientos astronómicos realizados por Galileo. Ambos científicos se conocieron cuando Galileo visitó Roma en 1587 y desde entonces mantuvieron correspondencia ocasional sobre cuestiones matemáticas. Cuando Clavius ??publicaba un libro, siempre enviaba una copia a su amigo Galileo. 1610, Clavius ??era un anciano y tuvo que ser extremadamente difícil comprender estos nuevos descubrimientos tanto desde un punto de vista científico como religioso. Como científico principal del Colegio Romano, se le pidió que emitiera un juicio sobre Galileo. Aún desde hace algún tiempo no disponía de un telescopio de calidad suficiente para realizar sus propias observaciones. Sin embargo, en la edición final de In sphaeram Ioannis de Sacro Bosco Commentarius, abordó los problemas: - "No quiero esconder al lector que no hace mucho tiempo se llevó cierto instrumento de Bélgica. Tiene la forma de un largo tubo en cuyas bases se colocan dos cristales, o más bien lentos, por los que los objetos lejanos de nosotros parecen mucho más cercanos. que las cosas mismas. nebulosas de Cáncer y Orión, en la Vía Láctea y otros lugares. y cuando la Luna está en cuarto creciente o medio lleno, parece tan notablemente fracturado y áspero que no puedo maravillarme que haya tal irregularidad en el cuerpo lunar. Nuncius, que describe varias observaciones de las estrellas hechas por él por primera vez. Lejos de lo menos importante de las cosas que se ven con este instrumento es que Venus recibe su luz del Sol al igual que la Luna, por lo que a veces se parece más a una media luna, a veces menos, según su distancia al Sol. En Roma he observado esto, en presencia de otras, más de una vez. Saturno le ha unido dos estrellas más pequeñas, una al este y otra al oeste. Siendo así las cosas, los astrónomos deberían considerar cómo se pueden disponer los orbes celestes para salvar estos fenómenos.".
