 The deciphering of the texts started immediately, and bilinguals, in particular Old Persian-Akkadian bilinguals, were of great help.Since the texts contained several royal names, isolated signs could be identified, and were presented in 1802 by Georg Friedrich Grotefend.By this time it was already evident that Akkadian was a Semitic language, and the final breakthrough in deciphering the language came from Edward Hincks, Henry Rawlinson and Jules Oppert in the middle of the 19th century.
