Cappadocia, after the death of Archelaus, the last of its kings, became a province of the Roman empire, as the rest of Asia also did much about the same time. Kings of Armenia. Armenia, a vast country of Asia, extending on each side of the Euphrates, was conquered by the Persians; after which it was transferred, with the rest of the empire, to the Macedonians, and at last fell to the share of the Romans. It was governed for a great length of time by its own kings, the most considerable of whom was Tigranes, who espoused the daughter of the great Mithridates king of Pontus, and was also engaged in a long war with the Romans. This kingdom supported itself many years, between the Roman and Parthian empires, sometimes depending on the one, and sometimes on the other, till at last the Romans became its masters. Kings of Epirus. Epirus is a province of Greece, separated from Thessaly and Macedonia by mount Pindus. The most powerful people of this country were the Molossians. The kings of Epirus pretended to derive their descent from Pyrrhus the son of Achilles, who established himself in that country, and called themselves Æacides, from Æacus the grandfather of Achilles. The genealogy of the latter kings, who were the only sovereigns of this country of whom any accounts remain, is variously related by authors, and consequently must be doubtful and obscure.(248) Arymbas ascended the throne, after a long succession of kings; and as he was then very young, the states of Epirus, who were sensible that the welfare of the people depends on the proper education of their princes, sent him to Athens, which was the residence and centre of all the arts and sciences, in order to cultivate, in that excellent school, such knowledge as was necessary to form the mind of a king. He there learned the art of reigning, and as he surpassed all his ancestors in ability and knowledge, he was in consequence infinitely more esteemed and beloved by his people than they had been.(249) When he returned from Athens, he made laws, established a senate and magistracy, and regulated the form of the government. Neoptolemus, whose daughter Olympias had espoused Philip king of Macedon, attained an equal share in the regal government with Arymbas his elder brother, by the influence of his son-in-law. After the death of Arymbas, Æacides his son ought to have been his successor; but Philip had still sufficient influence to procure his expulsion from the kingdom by the Molossians, who established Alexander the son of Neoptolemus sole monarch of Epirus. Alexander espoused Cleopatra the daughter of Philip, and marched with an army into Italy, where he lost his life in the country of the Brutians. Æacides then ascended the throne, and reigned without any associate in Epirus. He espoused Phthia, the daughter of Menon the Thessalian, by whom he had two daughters, Deidamia and Troias, and one son, the celebrated Pyrrhus.
