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

On the basis of this and the foreign names on the Rosetta Stone, he quickly constructed an alphabet of phonetic hieroglyphic characters, which appears in his famous 1822 ""Lettre à M.

In the postscript Champollion notes that similar phonetic characters seemed to occur in both Greek and Egyptian names, a
