The Persopolitane writing, which first vestiges were discovered in Persopolisīs city ruins is a cuneiform writing used to transcribe Persian language in the epoch of king Aquemenid (6 Th, 7 Th century BC). It is almost an alphabetic writing in which the vowel is considered inherent to the consonant. The origin of this writing is still unknown, although the Greek tradition conferred this invention to Darios.
