The wife of the deceased, the queen Bat Zabbai, or in Greek, Zenobia, a beautiful and sagacious woman of masculine energy,[108] in virtue of the hereditary right to the principate claimed for the son of herself and Odaenathus, still in boyhood, Vaballathus or Athenodorus[109]--the elder, Herodes, had perished with his father--the position of the deceased, and in fact carried her point as well in Rome as in the East: the regnal years of the son are reckoned from the death of the father. For the son, not capable of government, the mother took part in counsel and action,[110] and she did not restrict herself to preserving the state of possession, but on the contrary her courage or her arrogance aspired to mastery over the whole imperial domain of the Greek tongue. In the command over the East, which was committed to Odaenathus and inherited from him by his son, the supreme authority over Asia Minor and Egypt may doubtless have been included; but _de facto_ Odaenathus had in his power only Syria and Arabia, and possibly Armenia, Cilicia, and Cappadocia. Now an influential Egyptian, Timagenes, summoned the queen to occupy Egypt; accordingly she despatched her chief general Zabdas with an army of, it is alleged, 70,000 men to the Nile. The land resisted with energy; but the Palmyrenes defeated the Egyptian levy and possessed themselves of Egypt. A Roman admiral Probus attempted to dislodge them again, and even vanquished them, so that they set out for Syria; but, when he attempted to bar their way at the Egyptian Babylon not far from Memphis, he was defeated by the better local knowledge of the Palmyrene general Timagenes, and he put himself to death.[111] When about the beginning of the year 270, after the death of the emperor Claudius, Aurelian came in his stead, the Palmyrenes bore sway over Alexandria. In Asia Minor too they made preparations to establish themselves; their garrisons were pushed forward as far as Ancyra in Galatia, and even in Chalcedon opposite Byzantium they had attempted to assert the rule of their queen. All this happened without the Palmyrenes renouncing the Roman government, nay probably on the footing that the control of the East committed by the Roman government to the prince of Palmyra was realised in this way, and they taxed the Roman officers, who resisted the extension of the Palmyrene rule, with rebellion against the imperial orders; the coins struck in Alexandria name Aurelianus and Vaballathus side by side, and give the title of Augustus only to the former. In substance, no doubt, the East here detached itself from the empire, and the latter was divided into two in the execution of an ordinance wrung from the wretched Gallienus by necessity.
