the Indus in the Indian Subcontinent which were annexed during the Achaemenid conquest of the Indus Valley. DNf inscription. There are various and contradictory reports about how this inscription was discovered. According to Mrs. Khadija Totunchi, she took a photo of this inscription in 2017. But she did not find a suitable person to translate and read the inscription. Also, according to Ebrahim Rustaei, in 2018, in cooperation with Abdul Majid Arfai, he presented an article about the inscription to the International Conference on History and Culture of Southern Iran (Historical Persia), in which a reading of the inscription was presented. However, this reading is very basic and has many flaws. But finally, the DNf petroglyph, which had been hidden in the shade and under algae and sediments for 2500 years, was officially and scientifically recorded by Mojtaba Doroodi and Soheil Delshad in February 2019.

Ka'ba-ye Zartosht Ka'ba-ye Zartosht (meaning the "Cube of Zoroaster") is a 5th-century B.C Achaemenid square tower. The structure is a copy of a sister building at Pasargadae, the "Prison of Solomon" (Zendān-e Solaymān). It was built either by Darius I (r. 521–486 BCE) when he moved to Persepolis, by Artaxerxes II (r. 404–358 BCE) or Artaxerxes III (r. 358–338 BCE). The building at Pasargadae is a few decades older. There are four inscriptions in three languages from the Sasanian period on the lower exterior walls. They are considered among the most important inscriptions from this period. Several theories exist regarding the purpose of the Ka'ba-ye Zartosht structure. Sassanid reliefs Seven over-life sized rock reliefs at Naqsh-e Rostam depict monarchs of the Sassanid period. Their approximate dates range from AD 225 to 310, and they show subjects including investiture scenes and battles. Investiture relief of Ardashir I, c. 226–242 The founder of the Sassanid Empire is seen being handed the ring of kingship by Ohrmazd. In the inscription, which also bears the oldest attested use of the term Iran, Ardashir admits to betraying his pledge to Artabanus V (the Persians having been a vassal state of the Arsacid Parthians), but legitimizes his action on the grounds that Ohrmazd had wanted him to do so. The word ērān is first attested in the inscriptions that accompany the investiture relief of Ardashir
