The first wall is regularly fortified; the interior one, though less in substance, is of almost equal strength. Besides these, in the centre of each division of the city, there is a circular space surrounded by a wall. In one of these stands the royal palace, which fills a large and strongly defended space. The temple of Jupiter Belus occupies the other, whose huge gates of brass may still be seen. It is a square building, each side of which is of the length of two furlongs. In the midst a tower rises, of the solid depth and height of one furlong, upon which, resting as a base, seven other turrets are built in regular succession. The ascent is on the outside, which, winding from the ground, is continued to the highest tower; and in the middle of the whole structure there is a convenient resting-place. In the last tower is a large chapel, in which is placed a couch magnificently adorned, and near it a table of solid gold; but there is no statue in the place. No man is suffered to sleep here; but the apartment is occupied by a female, who, as the Chaldean priests affirm, is selected by their deity from the whole nation as the object of his pleasures.
They themselves have a tradition, which cannot easily obtain credit, that their deity enters this temple and reposes by night on this couch. A similar assertion is also made by the Egyptians of Thebes; for, in the interior part of the temple of the Theban Jupiter, a woman in like manner sleeps. Of these two women, it is presumed that neither of them has any communication with the other sex. In which predicament the priestess of the temple of Pataræ in Lycia is also placed. Here is no regular oracle; but whenever a divine communication is expected, the priestess is obliged to pass the preceding night in the temple.
In this temple there is also a small chapel, lower in the building, which contains a figure of Jupiter in a sitting posture, with a large table before him; these, with the base of the table and the seat of the throne, are all of the purest gold, and are estimated by the Chaldeans to be worth eight hundred talents. On the outside of this chapel there are two altars: one is of gold, the other is of immense size, and appropriated to the sacrifice of full-grown animals; those only which have not left their dams may be offered on the altar of gold. Upon the larger altar, at the time of the anniversary festival in honour of their god, the Chaldeans regularly consume incense, to the amount of a thousand talents. There was formerly in this temple a statue of gold, twelve cubits high; this, however, I mention from the information of the Chaldeans, and not from my own knowledge. Darius, the son of Hystaspes, endeavoured by sinister means to get possession of this, not daring openly to take it; but his son Xerxes afterwards seized it, putting the priest to death who endeavoured to prevent its removal. The temple, besides those ornaments which I have described, contains many offerings of individuals.
