Shapur I's inscription at the Ka'ba-ye Zartosht
Shapur I's Ka'ba-ye Zartosht inscription is an important inscription dating from Sasanian Persia. The inscription is located in today's Fars Province, Iran. There are some important inscriptions located on the outer walls of this building from Shapur I and Kartir. The inscriptions are in Middle Persian, Greek and Parthian language. The Middle Persian version of Shapur's inscription contains 35 lines, the Parthian version contains 30 lines and the Greek version contains 70 lines. The Greek and Parthian versions are better survived, while the Middle Persian version was damaged to some extend. Also, the Greek and Parthian texts are not exactly the same as the Middle Persian text. In this inscription, Shapur introduces himself, mentions the provinces of his empire, describes his campiagns against the neighboring rivalling Roman Empire and talks about the fire-temples he built. The inscription is considered the most important inscription from the Sasanian era.
