When Philometor was killed in battle, Physcon, or Euergetes II., laid siege to Alexandria, forced the widowed queen Cleopatra II. to marry him, murdered her young son Ptolemy, Philopator Neos, the rightful heir, for whom the mother had made a bold attempt to maintain the throne, and reigned as Ptolemy VII. Physcon even married the queen's daughter, Cleopatra III., and we see this remarkable man managing, at the same time, two ambitious queens, mother and daughter, who were probably at deadly enmity throughout the period in which they were associated with him in the royalty. One story, almost too horrible to obtain credence, tells that Physcon served up as a birthday feast to the mother, Cleopatra II., his own heir Memphitis. When this wretch finally ended his days, Cleopatra III., who was as great a monster of ambition, selfishness, and cruelty as Physcon himself, seems to have murdered her queen-mother and to have assumed the reins of government, at first alone, and later associated with her eldest son, Lathyrus Soter II., who reigned as the eighth Ptolemy. Lathyrus first married his sister Cleopatra IV., but was finally compelled by his mother to divorce her and to marry his other sister, Selene. He was finally turned out of his kingdom by his mother, who desired the accession of his younger brother, Alexander I., the ninth Ptolemy; and the latter repaid her maternal interest in him by murdering her as soon as he was secure on the throne. His queen was Berenice III., with whom he reigned until they were in turn ousted by Lathyrus. Alexander II., Ptolemy X., succeeded Lathyrus, and married his stepmother, Berenice III., whom he speedily murdered, and was himself put to death after a brief reign of nineteen days. Ptolemy XI., Auletes, an illegitimate son of Soter II., then mounted the throne, his queen being Cleopatra V., Tryphaena. He was the last and the weakest of the Ptolemies, and is worthy of mention merely because of his base dealings with Rome, which introduced Roman intervention into Egyptian affairs, and because he was the father of the great Cleopatra.
