 The decipherment of Old Persian was notably useful to the decipherment of Elamite, Babylonian and ultimately Akkadian (predecessor of Babylonian), through the multi-lingual Behistun Inscription.Most scholars consider the writing system to be an independent invention because it has no obvious connections with other writing systems at the time, such as Elamite, Akkadian, Hurrian, and Hittite cuneiforms.While Old Persian's basic strokes are similar to those found in cuneiform scripts, Old Persian texts were engraved on hard materials, so the engravers had to make cuts that imitated the forms easily made on clay tablets.
