klē - ō̇ - pa´tra ( Κλεοπάτρα , Kleopátra , "from a famous father"): A daughter of Ptolemy Vi (Philometor) and of Queen Cleopatra, who was married first to Alexander Balas 150 bc (1 Macc 10:58; Josephus, Ant , Xiii , iv, 1) and was afterward taken from him by her father and given to Demetrius Nicator on the invasion of Syria by the latter (1 Macc 11:12; Josephus, Ant , Xiii , iv, 7). Alexander was killed in battle against the joint forces of Ptolemy and Demetrius while Demetrius was in captivity in Parthia. Cleopatra married his brother Antiochus Vii (Sidetes), who in the absence of Demetrius had gained possession of the Syrian throne (137 bc). She was probably privy (Appian, Syriac ., 68) to the murder of Demetrius on his return to Syria 125 bc, but Josephus ( Ant. , Xiii , ix, 3) gives a different account of his death. She afterward murdered Seleucus, her eldest son by Nicator, who on his father's death had taken possession of the government without her consent. She attempted unsuccessfully to poison her second son by Nicator, Antiochus Viii (Grypus), for whom she had secured the succession, because he was unwilling to concede to her what she considered her due Share of power. She was herself poisoned (120 bc) by the draught which she had prepared for their son (Justin 39). She had also a son by Antiochus Vii (Sidetes Antiochus Cyzicenus), who took his name from the place in which he was educated. He was killed in battle 95 bc. The name Cleopatra was borne by many Egyptian princesses, the first of whom was daughter of Antiochus Iii and was married to Ptolemy V (Epiphanes) 193 bc.
