From hence he marched through the province of Babylon, which immediately submitted to him, and in Ecbatana was much surprised at the sight of the place where fire issues in a continuous stream, like a spring of water, out of a cleft in the earth, and the stream of naphtha, which, not far from this spot, flows out so abundantly as to form a sort of lake. This naphtha, in other respects resembling bitumen, is so subject to take fire, that before it touches the flame it will kindle at the very light that surrounds it, and often inflame the intermediate air also. The barbarians, to show the power and nature of it, sprinkled the street that led to the king's lodgings with little drops of it, and when it was almost night, stood at the further end with torches, which being applied to the moistened places, the first at once taking fire, instantly, as quick as a man could think of it, it caught from one end to another, in such a manner that the whole street was one continued flame. Among those who used to wait on the king and find occasion to amuse him when he anointed and washed himself there was one Athenophanes, an Athenian, who desired him to make an experiment of the naphtha upon Stephanus, who stood by in the bathing place, a youth with a ridiculously ugly face, whose talent was singing well, "For," said he, "if it take hold of him and is not put out, it must undeniably be allowed to be of the most invincible strength." The youth, as it happened, readily consented to undergo the trial, and as soon as he was anointed and rubbed with it, his whole body broke out into such a flame, and was so seized by the fire, that Alexander was in the greatest perplexity and alarm for him, and not without reason; for nothing could have prevented his being consumed by it, if by good chance there had not been people at hand with a great many vessels of water for the service of the bath, with all which they had much ado to extinguish the fire; and his body was so burned all over that he was not cured of it for a good while after. Thus it is not without some plausibility that they endeavour to reconcile the fable to truth, who say this was the drug in the tragedies with which Medea anointed the crown and veil which she gave to Creon's daughter. For neither the things themselves, nor the fire, could kindle of its own accord, but being prepared for it by the naphtha, they imperceptibly attracted and caught a flame which happened to be brought near them. For the rays and emanations of fire at a distance have no other effect upon some bodies than bare light and heat, but in others, where they meet with airy dryness, and also sufficient rich moisture, they collect themselves and soon kindle and create a transformation. The manner, however, of the production of naphtha admits of a diversity of opinion... of whether this liquid substance that feeds the flame does not rather proceed from a soil that is unctuous and productive of fire, as that of the province of Babylon is, where the ground is so very hot that oftentimes the grains of barley leap up and are thrown out, as if the violent inflammation had made the earth throb; and in the extreme heats the inhabitants are wont to sleep upon skins filled with water. Harpalus, who was left governor of this country, and was desirous to adorn the palace gardens and walks with Grecian plants, succeeding in raising all but ivy, which the earth would not bear, but constantly killed. For being a plant that loves a cold soil, the temper of this hot and fiery earth was improper for it. But such digressions as these the impatient reader will be more willing to pardon if they are kept within a moderate compass.
At the taking of Susa, Alexander found in the palace forty thousand talents in money ready coined, besides an unspeakable quantity of other furniture and treasure; amongst which was five thousand talents' worth of Hermionian purple, that had been laid up there an hundred and ninety years, and yet kept its colour as fresh and lively as at first. The reason of which, they say, is that in dyeing the purple they made use of honey, and of white oil in the white tincture, both which after the like space of time preserve the clearness and brightness of their lustre. Dinon also relates that the Persian kings had water fetched from the Nile and the Danube, which they laid up in their treasuries as a sort of testimony of the greatness of their power and universal empire.
