- Rosetta Stone (n.)
[Rosetta Stone 词源字典]
- discovered 1798 at Rosetta, Egypt; now in British Museum. Dating to 2c. B.C.E., its trilingual inscription helped Jean-François Champollion decipher Egyptian demotic and hieroglyphics in 1822, which opened the way to study of all early Egyptian records. Hence, figurative use of the term to mean "something which provides the key to previously unattainable understanding" (1902). The place name is the European form of Rashid, a name given because it was founded c.800 C.E. by Caliph Harun ar-Rashid.[Rosetta Stone etymology, Rosetta Stone origin, 英语词源]
