The famous Arabian queen was the widow of Odenathus, of Palmyra, who bequeathed to her his dignity as _Cæsar_, or protector of the Eastern dominions of Rome. It soon, however, became apparent that she disdained to owe allegiance to the Roman emperors, and aimed at establishing a new great empire for herself and her descendants. Though the most accomplished, as well as the most beautiful woman of her time, she led her armies in person, and was so eminently successful in her military enterprises that she soon extended her dominion from the Euphrates to the Nile. Palmyra thus became the centre and capital of a vast empire, which, as Mr. Gobineau observes, rivalled and even threatened Rome itself. She was, however, defeated by Aurelian, and, in A. D. 273, graced the triumph of her conqueror on his return to Rome. The former splendor of the now deserted Palmyra is attested by the magnificent ruins which still form an inexhaustible theme for the admiration of the traveller and antiquarian.--H. [187] Though the mass of the nation were ignorant of letters, the Arabs had already before Mohammed's times some famous writers. They had even made voyages of discovery, in which they went as far as China. The earliest, and, as modern researches have proved, the most truthful, account of the manners and customs of that country is by Arab writers.--H. [188] At the time of the appearance of the false prophet, Arabia contained within its bosom every then known religious sect. This was owing not only to the central position of that country, but also to the liberty which was then as now a prerogative of the Arab. Among them every one was free to select or compose for himself his own private religion. While the adjacent countries were shaken by the storms of conquest and tyranny, the persecuted sects fled to the happy land where they might profess what they thought, and practice what they professed.
