The long street just described terminates in a large open space (f) enclosed by a magnificent semicircle of columns in a single row; fifty- seven columns are yet standing; originally there may have been about eighty. To the right, on entering the forum, are four, and then twenty- one, united by their entablatures. To the
[p.257]left, five, seven, and twenty, also with entablatures; the latter twenty are taller than the others, the lower ground on which they stand having required an increased height of column in order to place the whole entablature of the semicircle on the same level. The pillars near the entrance are about fifteen feet in height, and one foot and a half in diameter: they are all of the Ionic order, and thus they differ from all the other columns remaining in the city. The radius of the semicircle, in following the direction of the long street, was one hundred and five paces.
At the end of the semicircle, opposite to the long street, are several basins, which seem to have been reservoirs of water, and remains of an aqueduct are still visible, which probably supplied them. To the right and left are some low arched chambers. From this spot the ground rises, and on mounting a low but steep hill before me, I found on its top the remains of a beautiful temple (g), commanding a view over the greater part of the town. The front of the temple does not stand directly opposite to the long street and the forum, but declines somewhat to the northward. Like the temple first described, it was adorned with a Corinthian peristyle, of which one column only remains, at the south angle. In front was a double row of columns, with eight, as I conjecture, in each row. They seem to have been thrown down by an earthquake, and many of them are now lying on the declivity of the hill, in the same order in which they originally stood. They are six spans and a half in diameter, and their capitals appeared to me of a still finer execution than those of the great temple. I am unable to judge of the number of columns on the long sides of the peristyle: their broken shafts lie about in immense heaps. On every side of the temple except the front, there appears to have been a large ditch round the temple. Of the cella the walls only remain, the roof, entrance, and back wall having
