Rosetta Stone
/rəʊˈzetə/1
- an inscribed stone found near Rosetta on the western mouth of the Nile in 1799. Its text is written in three scripts: hieroglyphic, demotic, and Greek. The deciphering of the hieroglyphs by Jean-François Champollion in 1822 led to the interpretation of many other early records of Egyptian civilization.罗塞塔石碑（1799年在尼罗河西河口罗塞塔附近发现的石碑, 其碑文用象形文字, 古埃及通俗文字和希腊文字等三种文字刻成; 1822年让-弗朗索瓦·商博良对铭文中象形文字的释读使埃及文明的其他许多早期记录得到解释）。
