The appellation of Roumelia, which is still bestowed by the Turks on the extensive countries of Thrace, Macedonia, and Greece, preserves the memory of their ancient state under the Roman empire. In the time of the Antonines, the martial regions of Thrace, from the mountains of Hæmus and Rhodope, to the Bosphorus and the Hellespont, had assumed the form of a province. Notwithstanding the change of masters and of religion, the new city of Rome, founded by Constantine on the banks of the Bosphorus, has ever since remained the capital of a great monarchy. The kingdom of Macedonia, which, under the reign of Alexander, gave laws to Asia, derived more solid advantages from the policy of the two Philips; and with its dependencies of Epirus and Thessaly, extended from the Ægean to the Ionian Sea. When we reflect on the fame of Thebes and Argos, of Sparta and Athens, we can scarcely persuade ourselves, that so many immortal republics of ancient Greece were lost in a single province of the Roman empire, which, from the superior influence of the Achæan league, was usually denominated the province of Achaia. Such was the state of Europe under the Roman emperors. The provinces of Asia, without excepting the transient conquests of Trajan, are all comprehended within the limits of the Turkish power. But, instead of following the arbitrary divisions of despotism and ignorance, it will be safer for us, as well as more agreeable, to observe the indelible characters of nature. The name of Asia Minor is attributed with some propriety to the peninsula, which, confined betwixt the Euxine and the Mediterranean, advances from the Euphrates towards Europe. The most extensive and flourishing district, westward of Mount Taurus and the River Halys, was dignified by the Romans with the exclusive title of Asia. The jurisdiction of that province extended over the ancient monarchies of Troy, Lydia, and Phrygia, the maritime countries of the Pamphylians, Lycians, and Carians, and the Grecian colonies of Ionia, which equalled in arts, though not in arms, the glory of their parent. The kingdoms of Bithynia and Pontus possessed the northern side of the peninsula from Constantinople to Trebizond. On the opposite side, the province of Cilicia was terminated by the mountains of Syria: the inland country, separated from the Roman Asia by the River Halys, and from Armenia by the Euphrates, had once formed the independent kingdom of Cappadocia. In this place we may observe, that the northern shores of the Euxine, beyond Trebizond in Asia, and beyond the Danube in Europe, acknowledged the sovereignty of the emperors, and received at their hands either tributary princes or Roman garrisons.
