inquiry to be made "for all the ancient books which treated of the admirable art of making gold and silver, and without pity, committed them to the flames; apprehensive, as we are assumed, lest the opulence of the Egyptians should inspire them with confidence to rebel against the empire." But if Diocletian had been convinced of the reality of that valuable art, far from extinguishing the memory, he would have converted the operation of it to the benefit of the public revenue. It is much more likely, that his good sense discovered to him the folly of such magnificent pretensions, and that he was desirous of preserving the reason and fortunes of his subjects from the mischievous pursuit. It may be remarked, that these ancient books, so liberally ascribed to Pythagoras, to Solomon, or to Hermes, were the pious frauds of more recent adepts. The Greeks were inattentive either to the use or to the abuse of chemistry. In that immense register, where Pliny has deposited the discoveries, the arts, and the errors of mankind, there is not the least mention of the transmutation of metals; and the persecution of Diocletian is the first authentic event in the history of alchemy. The conquest of Egypt by the Arabs diffused that vain science over the globe. Congenial to the avarice of the human heart, it was studied in China as in Europe, with equal eagerness, and with equal success. The darkness of the middle ages insured a favorable reception to every tale of wonder, and the revival of learning gave new vigor to hope, and suggested more specious arts of deception. Philosophy, with the aid of experience, has at length banished the study of alchemy; and the present age, however desirous of riches, is content to seek them by the humbler means of commerce and industry.

The reduction of Egypt was immediately followed by the Persian war. It was reserved for the reign of Diocletian to vanquish that powerful nation, and to extort a confession from the successors of Artaxerxes, of the superior majesty of the Roman empire.

We have observed, under the reign of Valerian, that Armenia was subdued by the perfidy and the arms of the Persians, and that, after the assassination of Chosroes, his son Tiridates, the infant heir of the monarchy, was saved by the fidelity of his friends, and educated under the protection of the emperors. Tiridates derived from his exile such advantages as he could never have obtained on the throne of Armenia; the early knowledge of adversity, of mankind, and of the Roman discipline. He signalized his youth by deeds of valor, and displayed a matchless dexterity, as well as strength, in every martial exercise, and even in the less honorable contests of the Olympian games. Those qualities were more nobly exerted in the defence of his benefactor Licinius. That officer, in the sedition which occasioned the death of Probus, was exposed to the most imminent danger, and the enraged soldiers were forcing their way into his tent, when they were checked by the single arm of the Armenian prince. The gratitude of Tiridates contributed soon afterwards to his restoration. Licinius was in every station the friend and companion of Galerius, and the merit of Galerius, long before he was raised to the dignity of Cæsar, had been known and esteemed by Diocletian. In the third year of that emperor's reign Tiridates was invested with the kingdom of Armenia. The justice of the measure was not less evident than its expediency. It was time to rescue from the usurpation of the Persian monarch an important territory, which, since the reign of Nero, had been always granted under the protection of the empire to a younger branch of the house of Arsaces.

When Tiridates appeared on the frontiers of Armenia, he was received with an unfeigned transport of joy and loyalty. During twenty-six years, the country had experienced the real and imaginary hardships of a foreign yoke. The Persian monarchs adorned their new conquest with magnificent buildings; but those monuments had been erected at the expense of the people, and were abhorred as badges of slavery. The apprehension of a revolt had inspired the most rigorous precautions: oppression had been aggravated by insult, and the consciousness of the public hatred had been productive of every measure that could render it still more implacable. We have already remarked the intolerant spirit of the Magian religion. The statues of the deified kings of Armenia, and the sacred images of the sun and moon, were broke in pieces by the zeal of the conqueror; and the perpetual fire of Ormuzd was kindled and preserved upon an altar erected on the summit of Mount Bagavan. It was natural, that a people exasperated by so many injuries, should arm with zeal in the cause of their independence, their religion, and their hereditary sovereign. The torrent bore down every obstacle, and the Persian garrisons retreated before its fury. The nobles of Armenia flew to the standard of Tiridates, all alleging their past merit, offering their future service, and soliciting from the new king those honors and rewards from which they had been excluded
