In 244 A.D., Ardeshir I founded the Sassanid Dynasty, the last native Persian Kingdom to rule Ancient Iran before the Islamic conquest. The Sassanid era was a golden age of Persian culture that witnessed the revival of Zoroastrianism, an ancient mystical religion native to these lands, and a literary Renaissance spurred by the translation of many Old Persian epics recorded in cuneiform into the Middle Persian language of Pahlavi written in an alphabet derived from Aramaic. By introducing heightened international trade and commerce they created a legacy of political and economic diplomacy. They sponsored trade with the Romans (later on the Byzantines), their archenemy, to the west and the Chinese to the east. Excavations in China have unearthed gold and silver Sassanid coins covering a span of many centuries until the demise of the Empire during the reign of Khosrow II. However, the fall of the Empire had already started with a series of wars waged under the rule of Khosrow I, the father of Khosrow II. Challenged by the intensification of the same international commerce that had bore such wealth, struggles for national power and international prestige had escalated to an ungovernable degree. In the face of threats to his royal house, Khosrow II embarked upon military campaigns that would prove unsuccessful. By the close of his reign, the once mighty Sassanid Empire came to an end, paving the way for the rise of Islam in the Middle East.

In the east, the mighty Sassanid empire rivaled Rome in size and splendor, heirs to the earlier Persian Empire, the Sassanid were kings in the oriental manner, surrounded by riches and ritual. The Sassanid nobility were also bold warriors, whose armies frequently triumphed over the legions of Rome. This superb seal depicts a Sassanid king with flowing hair, arrayed in robes of state. Such an object may have been a symbol of royal authority, used to seal official documents, or perhaps a gift from the king to a favored courtier. As we press it into clay or wax today, admiring its image of serene kingship, we cannot help but reflect on vanished glory, the inevitable course of history.
