This metropolis, at that time the third in importance in the world, seemed, at a distance, to hang from the sides of the Coryphean mountains. Long before entering the harbour of Seleucia, voyagers were astonished to see the gigantic military forts which scaled the rocky slopes and crowned the summit with their crenelated walls. The city itself was on the banks of the Orontes, a white mass gleaming through the cypress trees. In addition to the theatres, gymnasiums, aqueducts, circuses, and race-courses, common to all large capitals, that of Syria had a Corso, a wide avenue, bordered from one end to the other by quadruple lines of columns. This splendid boulevard was a rendezvous for the world of fashion, and a constant stream of people passed up and down it day and night; on certain days the life and animation surpassed even that of the Roman Forum. The innumerable attractions of Antioch, especially since the decline of Athens, had brought many people to settle there, and it had, as well, a large floating population: Persians, Jews, Orientals of every country, to say nothing of the courtesans who flocked there from Susa, Ecbatana, often from the banks of the Ganges. Under the influence of these transient dwellers and of its tremendous commercial power, equalled only by that of Alexandria, manners and morals had gradually become corrupt. It was declared to be the most depraved city between Paphlagonia and Palmyra, a region noted for its scandalous living. As an example of the loose customs of the day, when the feast of Maia was celebrated, groups of naked girls ran through the streets, waving torches, while others, in like state, swam in the clear waters of the fishing pools, in full sight of the crowds.
