To perpetuate the memory of his success, he chose the same advantageous position for the principal Forum; which appears to have been of a circular, or rather elliptical form.

The two opposite entrances formed triumphal arches; the porticos, which enclosed it on every side, were filled with statues; and the centre of the Forum was occupied by a lofty column, of which a mutilated fragment is now degraded by the appellation of the burnt pillar.

This column was erected on a pedestal of white marble twenty feet high; and was composed of ten pieces of porphyry, each of which measured about ten feet in height, and about thirty-three in circumference.

On the summit of the pillar, above one hundred and twenty feet from the ground, stood the colossal statue of Apollo.

It was a bronze, had been transported either from Athens or from a town of Phrygia, and was supposed to be the work of Phidias.
