Rosetta Stone found, but later Egyptologists, including Wallis Budge, used these other copies to refine the reconstruction of the hieroglyphs that must have been used in the lost portions of the hieroglyphic text on the Rosetta Stone. Napoleon's 1798 campaign in Egypt came at (and helped cause) the beginning of a burst of Egyptomania in Europe, and especially France. A corps of 167 technical experts ("savants"), known as the "Commission des Sciences et des Arts", accompanied the French expeditionary army to Egypt. On 1799, French soldiers under the command of Colonel d'Hautpoul were strengthening the defences of Fort Julien, a couple of
Rosetta (spacecraft) on the Rosetta Stone catalysed the deciphering of the Egyptian writing system. Similarly, it was hoped that these spacecraft would result in better understanding of comets and the early Solar System. In a more direct analogy to its namesake, the "Rosetta" spacecraft also carried a micro-etched pure nickel prototype of the Rosetta disc donated by the Long Now Foundation. The disc was inscribed with 6,500 pages of language translations. The "Rosetta" mission achieved many historic firsts. On its way to comet 67P, "Rosetta" passed through the main asteroid belt, and made the first European close encounter with several of these
