Available in PDF, EPUB and Kindle. Book excerpt: English summary: 800 sundials of the Antiquity are known and preserved in museums. There are tens of thousands of them in Europe built between the Middle Ages and today. France alone has more than 32,000. The vast majority of them are still in operation on churches, in gardens, on public buildings or on private houses. In A History of sundials in the West, Denis Savoie reminds us of the heritage of Greco-Roman gnomonics and then examines the medieval achievements that reflect the clear decline of astronomy in the West. A profound change began in the measurement of time at the end of the Middle Ages and the beginning of the Renaissance, with the appearance of clocks and the abandonment of ancient timekeeping. The development of mathematics, the diffusion of the first printed works in the 16th century, the increase in the precision of the dials on which clocks are now set, all these factors contribute to massively spread these instruments which will remain for a long time the only way to know the time in the cities and the countryside. Sundials became an inexhaustible field of research and many types were built, from the luxurious pocket portables to the meridian in the cathedrals while passing by the simple dials which decorate the facades. Even if the 19th century relegates them to the background, sundials have never ceased to be at the same time objects of art often decorated with mottos and scientific and educational instruments essential to the understanding of the movements of the Sun. A unique synthesis of gnomonics, this richly illustrated History of sundials allows us to discover all the facets of an instrument that goes back to the beginnings of astronomy. Denis Savoie, historian of science, is a scientific advisor at Universcience (Palais de la Decouverte & Cite des Sciences et de l'Industrie) and an associate researcher at the Observatoire de Paris (Syrte). He chaired for twenty years the Sundial Commission. French description: 800 cadrans solaires de l'Antiquite sont connus et conserves dans les musees. Il en existe des dizaines de milliers en Europe construits entre le Moyen Age et aujourd'hui. La France en compte a elle seule plus de 32 000. La grande majorite fonctionne encore sur les eglises, dans les jardins, sur les batiments publics ou sur les maisons privees. Dans Une histoire des cadrans solaires en Occident, Denis Savoie rappelle l'heritage de la gnomonique greco-romaine puis examine les realisations medievales qui traduisent le net recul de l'astronomie en Occident. Un profond changement s'amorce dans la mesure du temps a la fin du Moyen Age et au debut de la Renaissance, avec l'apparition des horloges mecaniques et l'abandon des heures antiques. Le developpement des mathematiques, la diffusion des premiers ouvrages imprimes au XVIe siecle, l'augmentation de la precision des cadrans sur lesquels se reglent desormais les horloges, tous ces facteurs contribuent a massivement diffuser ces instruments qui vont pour longtemps rester la seule facon de connaitre l'heure dans les villes et les campagnes. Les cadrans solaires deviennent un domaine de recherche inepuisable et il s'en construit de nombreux types, des portables luxueux de poche jusqu'aux meridiennes dans les cathedrales en passant par les simples cadrans qui ornent les facades. Meme si le XIXe siecle les relegue au second plan, les cadrans solaires n'ont jamais cesse d'etre a la fois des objets d'art souvent ornes de devises et des instruments scientifiques et pedagogiques indispensables a la comprehension des mouvements du Soleil. Synthese unique de la gnomonique, cette Histoire des cadrans solaires, richement illustree, nous fait decouvrir toutes les facettes d'un instrument qui remonte aux debuts de l'astronomie.
