In ancient times Babylon was the metropolis of Assyria; but now Seleucia is the metropolis, I mean the Seleucia on the Tigris, as it is called. Nearby is situated a village called Ctesiphon, a large village. This village the kings of the Parthians were wont to make their winter residence, thus sparing the Seleucians, in order that the Seleucians might not be oppressed by having the Scythian folk or soldiery quartered amongst them. Because of the Parthian power, therefore, Ctesiphon is a city rather than a village; its size is such that it lodges a great number of people, and it has been equipped with buildings by the Parthians themselves; and it has been provided by the Parthians with wares for sale and with the arts that are pleasing to the Parthians; for the Parthian kings are accustomed to spend the winter there because of the salubrity of the air, but they summer at Ecbatana and in Hyrcania because of the prevalence of their ancient renown.
