13. Egypt was singularly blessed in having three great kings, whose reigns filled one whole century. A change now ensued; but that change was brought about by the natural course of events; in fact, it could scarcely be expected that the court should remain untainted by such luxury as must have prevailed in a city, which was the main seat of trade, and the deposit of the treasures of the richest countries. 14. Ptolemy IV. surnamed Philopator. A debauchee and a tyrant, who, during the greater portion of his reign, remained under the tutelage of the crafty Sosibius, and, after the decease of that individual, fell into the yet more infamous hands of Agathocles and his sister Agathoclea. Philopator being contemporary with Antiochus the Great, the dangers that threatened Egypt under such a reign seemed to be doubled; they were, however, averted by the ill-deserved victory of Raphia (see above, p. 238). 15. Agathocles and his sister would fain have taken into their own hands the guardianship of his son Ptolemy V. surnamed Epiphanes, a child only five years old; but the people having risen up and made a terrible example of them, the office of guardian was confided to the younger Sosibius and to Tlepolemus. The reckless prodigality of the former soon gave rise to a feud between him and his colleague, who was at least cunning enough to keep up appearances. Meanwhile the critical posture in which the kingdom was placed, by the attack of the enleagued kings of Syria and Macedonia, compelled the nation to defer the regency to Rome and the senate, who had hitherto carefully cherished an amicable connection with Egypt. The regency confided to M. Lepidus, 201, who hands over the administration to Aristomenes of Acarnania. The sequel will show how decidedly important this step was for the ulterior destinies of Egypt. By the war of the Romans against Philip, and their differences with Antiochus, Egypt was, no doubt, for the present extricated from her embarrassment; but nevertheless in 198 she lost her Syrian possessions, notwithstanding Antiochus III. had promised to give them as a dowry to Cleopatra, the affianced bride, and subsequently the consort of the young king of Egypt. To this time, or about 197, belongs the celebrated inscription on the Rosetta stone, erected by the caste of priests as a tribute of gratitude for past benefits, after the consecration of the king at Memphis upon his coming of age: a monument important alike for palaeography, and for the knowledge of Egyptian administration.
