for the conquest of Media. From thence was derived the name of Persia, which was applied by the western nations to the whole land of Iran, the native appellation of the extensive plateau ranging from the Hindu Kush to the river Tigris. In Persis was situated Persepolis, the traditional capital of the Persians, where the sacred fires of the Zoroastrians was kept perpetually alight in a temple by the Magi. In a drunken freak, or perhaps as a signal to all Asia that he had succeeded to the sovreignty of Iran, the ancient city had been committed to the flames by Alexander;[1] but eventually a capital was reinstated on the old site, and in later centuries became known as Istakhr.[2] About 200 A.D. a reawakening of Persian aspirations became apparent, and a new Cyrus arose at Istakhr to lead his nation to the reconquest of their former empire. Ardeshir was the grandson of Sásán, who by a fortunate marriage had united the pre-eminence of the priestly caste with that of the princely house of Persis. Having gained possession of the local throne by his superior energy, he began to exercise himself in active warfare by attacking the neighbouring states, whose princes, like himself, were the vassals of the Parthian king. At first his operations were disregarded, and not until he had made himself the lord of a considerable territory was he summoned by his suzerain to explain his encroachments. His reply was a defiance and a challenge to battle. In the war which ensued Artabanus was overthrown by Ardeshír, and the Parthian dynasty of the Arsacidae was replaced by that of the Sassanidae (c. 227).
