ベヒストゥン碑文
The decipherment of the Old Persian Cuneiform script was at the beginning of the decipherment of all the other cuneiform scripts, as various multi-lingual inscriptions between the various cuneiform scripts were obtained from archaeological discoveries. The decipherment of Old Persian was the starting point for the decipherment of Elamite, Babylonian and ultimately Akkadian (predecessor of Babylonian), especially through the multi-lingual Behistun Inscription.
