Rosetta Stone have originally been displayed within a temple, possibly at nearby Sais. It was probably moved during the early Christian or medieval period, and was eventually used as building material in the construction of Fort Julien near the town of Rashid (Rosetta) in the Nile Delta. It was rediscovered there in July 1799 by a French soldier named Pierre-François Bouchard during the Napoleonic campaign in Egypt. It was the first Ancient Egyptian bilingual text recovered in modern times, and it aroused widespread public interest with its potential to decipher this previously untranslated hieroglyphic language. Lithographic copies and plaster casts began circulating
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
