SYRIA, OR THE KINGDOM OF THE SELEUCIDÆ (312-63 B.C.).—This kingdom, during the two centuries and more of its existence, played an important part in the political history of the world. Under its first king it comprised nominally almost all the countries of Asia conquered by Alexander, thus stretching from the Hellespont to the Indus. Its rulers were called Seleucidæ, from the founder of the kingdom, Seleucus Nicator.

Seleucus Nicator (312-280 B.C.), besides being a ruler of unusual ability, was a most liberal patron of learning and art. He is declared to have been "the greatest founder of cities that ever lived." Throughout his dominions he founded a vast number, some of which endured for many centuries. Antioch, on the Orontes, in Northern Syria, became, after Seleucia on the Tigris, the capital of the kingdom, and obtained an influence and renown as a centre of population and trade which have given its name a sure place in history.

The successors of Seleucus Nicator led the kingdom through checkered fortunes. On different sides provinces fell away and became independent states. [Footnote: The most important of these were the following:—1. PERGAMUS.—This was a state in western Asia Minor, which became independent upon the death of Seleucus Nicator (280 B.C.). Favored by the Romans, it gradually grew into a powerful kingdom, which at one time embraced a considerable part of Asia Minor. Its capital, also called Pergamus, became a most noted centre of Greek learning and civilization. 2. PARTHIA.—Parthia was a powerful Turanian state that grew up east of the Euphrates River (from about 255 B.C. to 226 A.D.). Its kings were at first formidable enemies of the rulers of Syria, and later of the Romans, whom they never allowed to make any considerable conquest beyond the Euphrates.] Antiochus III. (223-187 B.C.), called "the Great," raised the kingdom for a short time into great prominence; but attempting to make conquests in Europe, and further, giving asylum to the Carthaginian general Hannibal, he incurred the fatal hostility of Rome. Quickly driven by the Roman legions across the Hellespont, he was hopelessly defeated at the battle of Magnesia (190 B.C.). After this, the Syrian kingdom was of very little importance in the world's affairs. At last, brought again into collision with Rome, the country was overrun by Pompey the Great, and became a part of the Roman Republic, 63 B.C.

KINGDOM OF THE PTOLEMIES IN EGYPT (323-30 B.C.).—The Græco-Egyptian empire of the Ptolemies was by far the most important, in its influence upon the civilization of the world, of all the kingdoms that owed their origin to the conquests of Alexander. The founder of the house and dynasty was Ptolemy I., surnamed Soter (323-283 B.C.), one of Alexander's ablest generals. His descendants ruled in Egypt for nearly three centuries, a most important period in the intellectual life of the world. Under Ptolemy I., Alexandria became the great depot of exchange for the productions of the world. At the entrance of the harbor stood the Pharos, or light- house,—the first structure of its kind,—which Ptolemy built to guide the fleets of the world to his capital. This edifice was reckoned one of the Seven Wonders.

But it was not alone the exchange of material products that was comprehended in Ptolemy's scheme. His aim was to make his capital the intellectual centre of the world—the place where the arts, sciences, literatures, and even the religions, of the world should meet and mingle. He founded the famous Museum, a sort of college, which became the "University of the East," and established the renowned Alexandrian Library. Poets, artists, philosophers, and teachers in all departments of learning were encouraged to settle in Alexandria by the conferring of immunities and privileges, and by gifts and munificent patronage. His court embraced the learning and genius of the age.

Ptolemy II., Philadelphus (283-247 B.C.), followed closely in the footsteps of his father, carrying out, as far as possible, the plans and policies of the preceding reign. Under his successor, Ptolemy III., Euergetes (247-242 B.C.), the dominions of the Ptolemies touched their widest limits; while the capital Alexandria reached the culminating point in her fame as the centre of Hellenistic civilization.

Altogether the Ptolemies reigned in Egypt almost exactly three centuries (323-30 B.C.). Those rulers who held the throne for the last two hundred years were, with few exceptions, a succession of monsters, such as even Rome in her worst days could scarcely equal. The usage of intermarriage among the members of the royal family,—a usage in which the Ptolemies followed what was a custom of the ancient Pharaohs,—led to endless family quarrels, which resulted in fratricide, matricide, and all the dark deeds included in the calendar of royal crime. The story of the renowned Cleopatra, the last of the house of the Ptolemies, will be told in connection with Roman history, to which it properly belongs.

MACEDONIA AND GREECE.—From the time of the subjection of Greece by Philip and Alexander to the absorption of Macedonia into the growing dominions of Rome, the Greek cities of the peninsula were very much under the control or influence of the Macedonian kings. But the Greeks were never made for royal subjects, and consequently they were in a state of chronic revolt against this foreign authority.
