Original print folio untrimmed extracted Travellers in Lower and Upper Egypt Vivant Denon. Board composed of two views as described by the author: No.1 Plan and géométrale rise naourah machine or lift water. A. horizontal axis gear. B. Lever arm, at the end of which is power. C. The tank. D. The bucket wheel. E. The gear. F. The movement of the drive wheel. NOTE ON THE WHEEL BUCKET. The mechanism of the wheel is so simple that the only inspection plan design enough to do; there is only one word to say about the structure of the Ferris wheel. Four circumferences of about fifteen lines rendering each form edges; they are supported by small piece of wood of the same rendering placed perpendicularly to the plane of the wheel and spaced from each other lengthwise of a bucket; they simultaneously serve and support the edges, and support small plates that form the separation pots. This assembly is consolidated by nailed eight cross the plane of the wheel, and sometimes bonded together by their ends extend beyond the circumference of the wheel, with a string or small pieces of wood; its bars are used to assemble the wheel with its axis four piece of wood nailed on the cross obliquely, and fixed internally to the wheel, further increase the strength. This frame is covered with boards about four leagues thick. It appears that the Egyptians do not follow point method for cutting these boards; they employ manner that there is nothing lost, without regard to the form; two rows of rods, coated on each side, are still used to fix these boards also nailed to the edges. The opening of each bucket has three square inches of surface; which is intended to facilitate the entry of fluid has fifteen lines width and length for the thickness of the wheel. If the friction is disregarded in this machine, it is found that, in the case of balance, the power to the resistance as the product of the radius of the main wheel with the radius of the horizontal wheel is the product of the radius vertical gear by the lever arm: you can set the machine in motion with very poor strength by sufficiently increasing the radius of the vertical gear and the lever arm, or only one of these two dimensions, or by reducing the radius of the horizontal wheel; but in all these cases be lost on the time that the gain is on the force. The dimensions of the machine must be determined by considering the force that is ready to use. It is likely that the Egyptians succeeded, by trial and error, to obtain the most suitable size, given the strength of the animals they serve; these are usually two buffaloes or two oxen yoked to the fork that forms the end of the lever. When the machine dimensions are small as twelve feet or so to the diameter of the Ferris wheel, one of these animals is enough; sometimes they still use a horse or a camel; sometimes a donkey pulls forward, while a man or woman behind the push lever; sometimes farmers tired sitting on the fork, and so roam their hunting buffalo before them. The plan by an engineer, and the explanatory notes given to me by General Dugua. No. 2 is a picture of a story, the story of which is in the newspaper, tom. 1, p. 263 Light foxing, otherwise good condition. Published for the first time in two volumes, an atlas of engravings, Didot, in 1802, the 'Journey to the Lower and Upper Egypt proved so successful that it was translated in 1803 into English and German, and a few years later in Dutch and Italian, among others. Almost all boards are designed by Denon, who also engraved himself a few, including portraits of the inhabitants of Egypt, who still kept the freshness of sketches taken on the spot (our 104-111 ). Two dozen writers have also collaborated on the creation of which Baltard, Galen, Reville and other etchings. Dominique Vivant, Baron Denon says Vivant Denon, born in Givry January 4, 1747 and died in Paris April 27, 1825, is a writer, author, diplomat and French administrator. At the invitation of Bonaparte, he joined the expedition to Egypt in shipping from May 14, 1798 on the frigate "La Juno." Protected by French troops, he had the opportunity to travel the country in all directions in order to gather the material that was the basis for his artistic work and the most important literary. It supports in particular General Desaix in Upper Egypt, which he refers to numerous sketches, ink wash and other drawings in pen, black chalk, or chalk. He draws constantly, usually on his knee, standing or on horseback, and sometimes even under enemy fire. After a journey of 13 months during which he draws thousands of drawings, Vivant Denon returned to France with Bonaparte, and became the first artist to publish the story of the expedition. The 141 boards that accompany his diary retrace its entire journey from the coast of Corsica to the pharaonic monuments of Upper Egypt. Bonaparte then appointed Director General of the Central Museum of the Republic, which became the Napoleon Museum and the Royal Louvre and arts administrator. In 1805, Vivant Denon revival project of the Vendome column, which had been suspended in 1803 then organizes expeditions across Europe to raise imperial works of art which are plundered to be carried away to the Louvre. In 1814, Louis XVIII confirmed as head of the Louvre, one wing of which still bears his name today. It is considered a great precursor of museology, art history and Egyptology.
