Moses of Choren, the Armenian historian, who wrote about the year 440, thus addresses the person to whom his work is dedicated. "How should the vain and empty fables about Byrasp Astyages gain any portion of thy favour, or why shouldest thou impose on us the fatigue of elucidating the absurd, tasteless, senseless legends of the Persians about him? to wit, of his first injurious benefit of the demoniac powers which were subject to him, and how he could not deceive him who was deception and falsehood itself. Then, of the kiss on the shoulders, whence the dragons came, and how thenceforward the growth of vice destroyed mankind by the pampering of the belly, until at last a certain Rhodones bound him with chains of brass, and brought him to the mountain which is called Demavend; how Byraspes then dragged to a hill Rhodones, when he fell asleep on the way, but this last, awaking out of his sleep, brought him to a cavern of the mountain, where he chained him fast, and set an image opposite to him, so that, terrified by it, and held by the chains, he might never more escape to destroy the world." Here we have evidently the whole story of Zohak and Feridoon current in Persia in the fifth century; and any one who has reflected on the nature of tradition must be well aware that it must have existed there for centuries before. The very names are nearly the same. Taking the first syllable from Feridoon, it becomes nearly Rodon, and Biyraspi Aidahaki (the words of the Armenian text) signify the dragon Byrasp: Zohak is evidently nearly the same with the last word. This fable could hardly have been invented in the time of the Sassanian dynasty, who had not then been more than two centuries on the throne, much less during the period of the dominion of the Parthian Arsacides, who were adverse to everything Persian. We are therefore carried back to the times of the Kejanians, the Achæmenides of the Greeks; and it is by no means impossible that the tale of Zohak and Feridoon was known even to the host which Xerxes led to the subjugation of Greece.
