پیشینه‌ خط فارسی میانه و سیر تغییر و تحول آن بر اساس سکه‌ها از فروپاشی هخامنشیان تا روی کار آمدن ساسانیان

After the collapse of the Achaemenids, although the cuneiform line was no longer used, however, the Persian language continued to exist. In the beginning, this language was reserved only for the Persian tribes in the same province, and over time, this language became popular in the whole country, and its spread has been the whole of Iran. In the end, this language was declared as the official language of the whole country, Of course, it should be noted that throughout history, in each period, special lines were used to write the Persian language, which were invented by the Persians. We know that it was the Persians who invented cuneiform writing in the Achaemenid period. Then a script was invented by the Persians to write the Persian language, which was mentioned under the title of Parsig when the Sassanids came to power. Now the main issue is what was the line used for writing in the period between the collapse of the Achaemenid dynasty and the rise of the Sassanid dynasty. The truth is that after the extinction of Achaemenids, the Achaemenid Divan script, i.e. Aramaic, was inevitably used to write the Persian language. Of course, over time, the Iranians realized that they did not see the Aramaic script as suitable for writing the Persian language, and such an attitude led to the fact that the Iranians invented a new script for writing the Persian language.
