Avestan alphabet
The Avestan alphabet (Avestan: 𐬛𐬍𐬥 𐬛𐬀𐬠𐬌𐬭𐬫𐬵 transliteration: dīn dabiryªh, Middle Persian: transliteration: dyn' dpywryh, transcription: dēn dibīrīh, Persian: دین دبیره, romanized: din dabire) is a writing system developed during Iran's Sasanian era (226–651 CE) to render the Avestan language. As a side effect of its development, the script was also used for Pazend, a method of writing Middle Persian that was used primarily for Zend commentaries on the texts of the Avesta.
