S ZENOBIA AND LONGINUS. 353 born some time after 200 a.p., and had studied liter- ature and philosophy at Athens, Alexandria, and Rome, under the ablest teachers of the age. His learning was immense, and he is the first man to whom was applied the expression “a living library,” or, to give it its modern form, “a walking encyclo- pedia.” His writings were lively and penetrating, showing at once taste, judgment, and learning. We have only fragments of them, except the celebrated “Treatise on the Sublime,” which is one of the most notable of ancient critical productions. Under the advice of this distinguished counsellor, Zenobia entered upon a career which brought her disaster, but has also brought her fame. Her hus- band Odenathus had avenged Valerian, the Roman emperor, who had been taken prisoner and shame- fully treated by the Persian king. For this service he was confirmed in his authority by the senate of Rome. But after his death the senate refused to grant this authority to his widow, and called on her to deliver her dominion over to Rome. Under the advice of Longinus the martial queen refused, defied the power of Rome, and determined to maintain her empire in despite of the senate and army of the proud “master of the world.” War at once broke out. A Roman army invaded Syria, but was met by Zenobia with such warlike energy and skill that it was hurled back in defeat, and its commanding general, having lost his army, was driven back to Europe in disgrace. This success gave Zenobia the highest fame and power in the world of the Orient. The states of Arabia, Armenia, 1—2# 80*
