Persian is one of the Western Iranian languages within the Indo-Iranian branch of the Indo-European language family. The Old Persian language is one of the two directly attested Old Iranian languages (the other being Avestan). Old Persian appears primarily in the inscriptions, clay tablets, and seals of the Achaemenid era (c. 600 BCE to 300 BCE). Examples of Old Persian have been found in what is now Iran, Romania (Gherla), Armenia, Bahrain, Iraq, Turkey and Egypt, the most important attestation by far being the contents of the Behistun Inscription (dated to 525 BCE). Avestan is one of the Eastern Iranian languages within the Indo-European language family known only from its use as the language of Zoroastrian scripture, i.e. the Avesta. (Source: Wikipedia)
