(M13) It was not till after the battle of Ipsus in Phrygia, wherein Antigonus, and his son Demetrius, surnamed Poliorcetes, were defeated, and the former lost his life, that this partition was fully regulated and fixed. The empire of Alexander was then divided into four kingdoms, by a solemn treaty, as had been foretold by Daniel. Ptolemy had Egypt, Libya, Arabia, Cœlesyria, and Palestine. Cassander, the son of Antipater, obtained Macedonia and Greece. Lysimachus acquired Thrace, Bithynia, and some other provinces on the other side of the Hellespont and the Bosphorus. And Seleucus had Syria, and all that part of the greater Asia which extended to the other side of the Euphrates, and as far as the river Indus. Of these four kingdoms, those of Egypt and Syria subsisted, almost without any interruption, in the same families, through a long succession of princes. The kingdom of Macedonia had several masters of different families successively. That of Thrace was at last divided into several branches, and no longer constituted one entire body, by which means all traces of regular succession ceased to subsist. I. The Kingdom of Egypt. The kingdom of Egypt had fourteen monarchs, including Cleopatra, after whose death, those dominions became a province of the Roman empire. All these princes had the common name of Ptolemy, but each of them was likewise distinguished by a peculiar surname. They had also the appellation of Lagides, from Lagus the father of that Ptolemy who reigned the first in Egypt. The fourth and fifth volumes contain the histories of six of these kings, and I shall give their names a place here, with the duration of their reigns, the first of which commenced immediately upon the death of Alexander the Great. (M14) Ptolemy Soter. He reigned thirty-eight years and some months. (M15) Ptolemy Philadelphus. He reigned forty years including the two years of his reign in the lifetime of his father. (M16) Ptolemy Euergetes, twenty-five years. (M17) Ptolemy Philopator, seventeen. (M18) Ptolemy Epiphanes, twenty-four. (M19) Ptolemy Philometor, thirty-four. II. The Kingdom of Syria. The kingdom of Syria had twenty-seven kings; which makes it evident, that their reigns were often very short: and indeed several of these princes waded to the throne through the blood of their predecessors. They are usually called the Seleucidæ, from Seleucus, who reigned the first in Syria. History reckons up six kings of this name, and thirteen who are called by that of Antiochus; but they are all distinguished by different surnames. Others of them assumed different names, and the last, Antiochus XIII., was surnamed Epiphanes, Asiaticus, and Commagenus. In his reign Pompey reduced Syria into a Roman province, after it had been governed by kings for the space of two hundred and fifty years, according to Eusebius. The kings of Syria, the transactions of whose reigns are contained in the fourth and fifth volumes, are eight in number.
