The fourth volume contains the events for the space of one hundred and twenty years, under the first four kings of Egypt, _viz._ Ptolemy, the son of Lagus, who reigned thirty-eight years; Ptolemy Philadelphus, who reigned forty; Ptolemy Euergetes, who reigned twenty-five; and Ptolemy Philopator, whose reign continued seventeen. In order to throw some light upon the history contained therein, I shall, in the first place, give the principal events of it, in a chronological abridgement. Introductory to which, I must desire the reader to accompany me in some reflections, which have not escaped Monsieur Bossuet, with relation to Alexander. This prince, who was the most renowned and illustrious conqueror in all history, was the last monarch of his race. Macedonia, his ancient kingdom, which his ancestors had governed for so many ages, was invaded from all quarters, as a vacant succession; and after it had long been a prey to the strongest, it was at last transferred to another family. If Alexander had continued peaceably in Macedonia, the grandeur of his empire would not have excited the ambition of his captains; and he might have transmitted the sceptre of his progenitors to his own descendants; but, as he had not prescribed any bounds to his power, he was instrumental in the destruction of his house, and we shall behold the extermination of his family, without the least remaining traces of them in history. His conquests occasioned a vast effusion of blood, and furnished his captains with a pretext for murdering one another. These were the effects that flowed from the boasted bravery of Alexander, or rather from that brutality, which, under the specious names of ambition and glory, spread desolation, and carried fire and sword through whole provinces, without the least provocation, and shed the blood of multitudes who had never injured him. We are not to imagine, however, that Providence abandoned these events to chance; but, as it was then preparing all things for the approaching appearance of the Messiah, it was vigilant to unite all the nations that were to be first enlightened with the Gospel, by the use of one and the same language, which was that of Greece: and the same Providence made it necessary for them to learn this foreign tongue, by subjecting them to such masters as spoke no other. The Deity, therefore, by the agency of this language, which became more common and universal than any other, facilitated the preaching of the apostles, and rendered it more uniform. The partition of the empire of Alexander the Great, among the generals of that prince, immediately after his death, did not subsist for any length of time, and hardly took place, if we except Egypt, where Ptolemy had first established himself, and on the throne of which he always maintained himself without acknowledging any superior.
