Old Persian Cuneiform

Darius I (550-486 BC) claims credit for the invention of Old Persian Cuneiform in an inscription on a cliff at Behistun in south-west Iran. The inscription dates from 520 BC and is in three languages - Elamite, Babylonian and Old Persian. Some scholars are sceptical about Darius' claims, others take them seriously, although they think that Darius probably commissioned his scribes to create the alphabet, rather than inventing it himself.
