It is between 1787 and 1791 that Antoine Isaac Silvestre de Sacy deciphered the Pahlavi inscriptions of the Sassanid kings. Post-conquest Pahlavi Following the Islamic conquest of the Sassanids, the term Pahlavi came to refer to the (written) "language" of the southwest (i.e. Pārsi). How this came to pass remains unclear, but it has been assumed that this was simply because it was the dialect that the conquerors would have been most familiar with. As the language and script of religious and semi-religious commentaries, Pahlavi remained in use long after that language had been superseded (in general use) by Modern Persian and Arabic script had been adopted as the means to render it. As late as the 17th century, Zoroastrian priests in Iran admonished their Indian co-religionists to learn it. Post-conquest Pahlavi (or just Pahlavi) is also called Zoroastrian Pahlavi or Zoroastrian Middle Persian. Unicode Tables showing the letters and their names or pronunciations are available online.
