As documented through Kushano-Sassanid coinage and inscriptions, this period witnessed the incursion of Zoroastrian motifs and Sassanid political elements into the region, while (like in Iran) Hellenistic symbology and elements in coinage largely disappeared. Just as Buddhism was inching towards the Persian Gulf and eastern Iran, Sassanian inscriptions bear testimony to the imperial institutionalization of Zoroastrianism from Babylonia to Peshawar and the Makran Coast (in Baluchistan). The later Iranian shah Khosrow I imported many cultural ephemera from Gupta India, including a Sanskrit anthology of fables called the "Panchatantra" (which were translated into Pahlavi, eventually filtering into the "Shahnameh" by Ferdowsi) and even the game of chess ("chaturanga)."
