4 parties en 1 vol. in-12 de (16)-280 pp., 43 vignettes gravées sur bois pour la première partie, 63 pp., 25 vignettes gravées sur bois pour la deuxième partie, 1 f.n.ch., pp. [65]-106-(10) pp. 1 f.bl., 12 gravures sur bois pour la troisième partie. [Relié à la suite] :[HENRION (Didier)] Nottes sur les récréations mathématiques. Par D.H.P.E.M. Rouen, Charles Osmont, 1639. 39 pp., 4 vignettes gravées sur bois, vélin souple, dos lisse avec titre manuscrit (reliure de l?époque). Troisième édition du commentaire de Claude Mydorge sur La Récréation Mathématique de Jean Leucheron.L?ouvrage se compose de quatre parties, les deux premières contiennent des problèmes ?plaisants et facétieux? d?arithmétique, de géométrie, d?astrologie, de perspective et d?optique. La troisième partie est exclusivement consacrée aux feux d?artifice et contient des recettes pour la fabrication de la poudre. La dernière partie, par Henrion, professeur de mathématiques à Paris et l?un des premiers scientifiques à avoir rédigé un traité sur les logarithmes, renferme des notes et des corrections des erreurs se trouvant dans les parties précédentes.Le Jésuite Jean Leucheron (vers 1591-1670) était professeur de philosophie et de mathématiques. Il avait publié en 1624 à Pont-à-Mousson, sous le pseudonyme de H. van Etten, un rarissime ouvrage de jeux mathématiques intitulé La Récréation mathématique ou Entretiens facétieux sur plusieurs plaisants problèmes en fait d?arithmétique, de géométrie. Grand amateur de géométrie, le juriste, mathématicien, géomètre et physicien Claude Mydorge (1585?1647) développa également un goût particulier pour les jeux et récréations mathématiques et fit rapidement imprimer une nouvelle édition augmentée de ses commentaires de l?ouvrage de Leucheron.Mydorge collabora et se lia d?amitié avec Descartes. Son intérêt pour les sections coniques le conduisit aussi à s?intéresser aux lois de l?optique et à l?astronomie. « Claude Mydorge, a friend of Descartes and an eminent geometer, [.] was also well versed in optics » (DSB).Cet ouvrage connut un formidable succès et fut réimprimé à de très nombreuses reprises au cours du XVIIe siècle.Illustré de 84 charmantes vignettes sur bois représentant tous les sujets abordés, y compris un bois décrivant une camera obscura.Feuillet D (première partie) déchiré en coin avec perte de quelques lettres et feuillet B2 (deuxième partie) déchiré en marge avec perte de quelques lettres. Pâles mouillures, vélin sali avec perte de peau sur le second plat.

Hardcover. 2nd Edition. Paris, Chez Rolet Boutonné, 1638 [second edition]/ 1630. Octavo (170 × 105 mm), four parts bound as one volume, [xvi], 280; 64 (last blank); [63]-106, [12] (index, last three blank); and 39, [1] (blank) pages with woodcut printer's devices on the four title pages, and 84 illustrations throughout (approximately 80 woodcut illustrations and a few type-set diagrams). There are five leaves missing from the 'Troisième Partie' (F4, F5, G1, G4 and G5: pages 85-90, 95-96, and 101-104). Nineteenth century half calf and marbled boards (now lacking the leather corner-pieces, revealing earlier full vellum boards underneath); covers a little worn; light tidemark to the bottom inner corner of the text block throughout; a little worming to the top (blank) margin of the first 25 leaves; insect damage to the bottom edge (extending at most a few millimetres into the wide blank bottom margins); first title leaf dusty and a little soiled; the five missing leaves notwithstanding, overall a very presentable copy. The second edition of Claude Mydorge's expanded edition and critique of this popular early work of recreational mathematics, first published in 1624 and usually attributed to Jean Leurechon. Each of Leurechon's mathematical problems is reprinted here in roman type, with Mydorge's explanatory notes and criticism following in italic. The third part, albeit relatively insubstantial (only 44 well-illustrated pages), is devoted exclusively to fireworks and their construction, which probably explains the few missing leaves. The subtitle is: 'Composée d'un receuil de plusieurs plaisantes & recreatives inventions de feux d'artifice, plus la maniere de faire toutes sortes de fuzées, tant simples que doubles, avec leur composition, le tout representé par figures [sic]' [Comprising a collection of several pleasant and recreative inventions of fireworks, plus the manner of making all sorts of rockets, both single and double, with their composition, all represented in figures]. This third part, together with the second, made its first appearance in a 1628 edition of 'Récréations Mathématiques' published by Charles Osmont at Rouen. Their authorship has not been established (HEEFER, Albrecht: 'Récréations Mathématiques (1624), A Study on its Authorship, Sources and Influence', revised 7 October 2004). The fourth part, 'Nottes [sic] sur les Recreations .' is by D.H.P.E.M. [Denis Henrion, Professeur ès Mathématiques]. Claude Mydorge (1585-1647), French mathematician, was a friend of René Descartes, with whom he shared a strong interest in optics and the nature of vision. 'Mydorge's first major work was the "Examen du livre des Récréations mathématiques", published in 1630. As the title suggests, it was a work on recreational mathematics and was effectively a critique of Laurechon's [sic] book on the theme ['Récréations mathématiques' by the French Jesuit, Jean Leurechon, writing under the pen name of van Etten, first appeared in 1624]. However, it was through his work on conic sections that Mydorge made the greatest scientific impact' (The Cambridge Descartes Lexicon, online). Provenance: a 1713 signature on the first page; an early ownership inscription ('Micha[el] Hutchins His Book') on a preliminary page; 'G.S. Kingston Sept 1834' on the front pastedown: Sir George Strickland Kingston (1807-1880), the South Australian pioneer, engineer and politician (deputy-surveyor-general under Colonel William Light, co-discoverer of the River Torrens, first Speaker in the House of Assembly.

Hardcover. First edition. AUTHOR'S PRESENTATION COPY. First edition, extremely rare author's presentation copy, of all four books of this important work on conic sections, intended to provide the geometrical basis for the study of optics. "Mydorge's work on conic sections contains hundreds of problems published for the first time, as well as a multitude of ingenious and original methods that later geometers frequently used, usually without citing their source" (DSB). Books I and II (pp. 1-134) were first published separately in 1631; a second edition appeared in 1639 with two additional books. The present copy has the first edition of the first two books, with the 1631 title page, bound up with the last two books from the second edition. A printed paper slip Libri quatuor priores has been pasted over Liber primus et secundus on the title to accommodate the added books, and a large section of text has also been pasted over the original on page 67 corresponding to changes in book I made between the 1631 and 1639 editions. The 1631 edition is very much rarer than the 1639: OCLC lists only five copies of the former - Danish Royal Library (but this copy is actually of the 1641 edition), Columbia, NYPL, Zürich, BNF - but 24 of the latter; COPAC adds copies of the 1631 edition at Oxford, Cambridge and UCL. It is likely that the 1631 edition was printed in very small numbers and was mostly, if not entirely, intended for presentation: the copies at Columbia, Zürich and BNF all have authorial corrections. The only other copy of the 1631 edition to have appeared at auction was Michel Chasles' copy, last sold in 1972. "In his study of conic sections Mydorge continued the work of Apollonius, whose methods of proof he refined and simplified . Mydorge asserts that if from a given point in the plane of a conic section radii to the points of the curve are drawn and extended in a given relationship, then their extremities will be on a new conic section similar to the first. This statement constitutes the beginnings of an extremely fruitful method of deforming figures; it was successfully used by La Hire and Newton, and later by Poncelet and, especially, by Chasles, who named it deformation homographique. "Mydorge posed and solved the following problem in [book] III: 'On a given cone place a given conic section' - a problem that Apollonius had solved only for a right cone. Mydorge was also interested in geometric methods used in approximate construction, such as that of a regular heptagon. Another problem that Mydorge solved by approximation - although he did not clearly indicate his method - was that of transforming a square into an equivalent regular polygon possessing an arbitrary number of sides" (DSB) "Mydorge (1585-1647) was born in Paris to one of the wealthiest families in France. He was educated at the Jesuit College of La Flèche and subsequently trained as a lawyer, before embarking on a legal and administrative career. After serving as conseiller to the court of the Grand Châtelet, he became treasurer of the généralité of Amiens, the collector general being a direct agent of the king. Mydorge's chosen employment allowed him sufficient time to combine public office with the life of a savant. Residing in what remained of the ancient Palais des Tournelles, he first met Descartes around 1625, becoming one of his most faithful friends and helping to establish his reputation in Paris. The mathematician Claude Hardy, a leading figure in the scientific circles around Mersenne, Roberval, and Étienne Pascal, lodged with him while he was producing his edition of Euclid's Elements. "Mydorge shared with Descartes a strong interest in optics and the nature of vision. It is well known that in order to promote his friend's investigations on these topics, he commissioned the production of innumerable parabolic, hyperbolic, oval, and elliptic lenses, reputedly spending in excess of 100,000 écus on optical instruments over the years. Both men were interested particularly in refraction, and when Descartes, independently of Snell, discovered the law of refraction, he persuaded Mydorge to have a hyperbolic glass made in order to test his discovery" (Cambridge Descartes Lexicon). Mydorge was also a friend of Fermat and Mersenne, and in 1638 played a role in settling the dispute between Descartes and Fermat that had arisen when Fermat refuted Descartes' Dioptrique. Mydorge played an important role in Descartes' discovery of the sine law of refraction, which the two men almost certainly formulated in 1626 (Sasaki, p. 175). "In a letter to Mersenne from around 1627, Mydorge used a rule to calculate angles of refraction, given the angles of one pair of incident and refracted rays . The rule comes down to a cosecant 'law' . Later in the letter, Mydorge applied this rule to lenses and transformed it into sine form. Mydorge's rule embodies the two assumptions that formed the core of Descartes' derivation of the sine law in La Dioptrique" (pp. 126-127). Publication of the present work was sponsored by Sir Charles Cavendish (?1595-1654), to whom the book is dedicated - Mydorge calls Cavendish "extremely skilled in all mathematics and a very dear friend to me" (Malcolm & Stedall, p. 88). Cavendish seems to have developed contacts with foreign mathematicians and by the summer of 1631 was corresponding with Mydorge. In 1671 John Collins wrote "'they complaine in france (as we doe here) that their Booksellers will not undertake to print mathematicall Bookes there, thence it came to passe that the four latter books of Mydorge were never printed, as the former had not been unless Sir Charles Cavendish had given 50 crownes as a Dowry with it" (Collins to Gregory, 14 March 1671/2 in Newton, Correspondence 47). The manuscript of 'the four latter books' was apparently taken to England by Cavendish's brother William and Thomas Wriothesley, Earl of Southampton, and then lost. The first four books were reissued in 1641 and 1660, and under the title De sectionibus c.

Very rare fourth edition of the commentary of Claude Mydorge (1585-1647) on the Récreations mathématiques by "H. van Etten" (Jean Leurechon). Mydorge corrected the numerous mistakes made by Leurechon in these mathematical diversions and "added several physical experiments as well as comments that he claimed were intended only for his friends". Several of examples and comments by Mydorge, also appear in the works of his friend Descartes, making it "reasonable to conclude that many of the other mechanical problems discussed by Mydorge in this work were also known to Descartes and one can easily imagine Descartes as one of the friends participating in the discussions of these problems alluded to in the prefatory remarks" (Hattab).The "diversions" consist of numerous problems for which a mathematical solution is presented, most of them illustrated by a woodcut. For instance, Mydorge (following Leurechon) informs the reader how to make water in a glass boil without fire, "to make a door open from both sides; to build a bridge all round the earth which will not fall when its supports are removed; to keep all the water in the world in the air without a single drop falling to earth". The third chapter, on fireworks, contains even more spectacular problems, such as "if all the gunpowder in the world were put in a globe of glass or paper and set on fire all at once, what would happen? Nothing, since the pressure would be equal in every direction" (Thorndike).Binding soiled and spine with a few holes; lower part loose in binding. First 50 pages creased; several marks and thumbing throughout. A fair, probably well-used copy.l Worldcat (1 copy); for Mydorge: DSB IX, pp. 598-599; Hattab, Descartes on forms and mechanisms, pp. 90-92; Thorndike VII, pp. 593-594. Contemporary limp vellum, with the manuscript title on the spine. With numerous woodcut illustrations illustrating the problems.

La troisième partie est entièrement nouvelle et contient «a collection of many pleasant and recreative inventions of fireworks including the manner of making all kinds of rockets, single and double, with their composition all represented by figures » (Philip). La quatrième partie contient les Notes de Denis HENRION. Claude MYDORGE (1585-1647), qui était l'ami de Descartes et l'aidait à fabriquer des instruments d'optique, enrichit de ses remarques le traité de Jean Leurechon (1591-1670), l'un des premiers en langue française. Les récréations sont présentées sous forme de problème dont l'énoncé doit exciter la curiosité du lecteur : "Représenter en une chambre close tout ce qui se passe par dehors", par exemple. « A friend of Descartes and an eminent geometer, Mydorge was also well versed in optics. He possessed a lively curiosity and was open to all the new ideas of his age. Like Fermat, he belonged to that elite group of seventeenth-century scientists who pursued science as amateurs but nevertheless made contributions of the greatest importance to one or more fields of knowledge » (Biographical dictionary of mathematicians, T. III, pages 1770-71). Ex-dono manuscrit à l'encre noire en queue de la page de titre : « A Jacques Fleury et a ses amis ».
