The friendly offer of Sain, the Persian general, to conduct an embassy to the presence of the Great King, was accepted with the warmest gratitude, and the prayer for pardon and peace was humbly presented by the prætorian prefect, the prefect of the city, and one of the first ecclesiastics of the patriarchal church. But the lieutenant of Chosroes had fatally mistaken the intentions of his master. “It was not an embassy,” said the tyrant of Asia, “it was the person of Heraclius, bound in chains, that he should have brought to the foot of my throne. I will never give peace to the emperor of Rome till he has abjured his crucified God, and embraced the worship of the sun.” Sain was flayed alive, according to the inhuman practice of his country; and the separate and rigorous confinement of the ambassadors violated the law of nations, and the faith of an express stipulation. Yet the experience of six years at length persuaded the Persian monarch to renounce the conquest of Constantinople, and to specify the annual tribute or ransom of the Roman Empire: a thousand talents of gold, a thousand talents of silver, a thousand silk robes, a thousand horses, and a thousand virgins. Heraclius subscribed these ignominious terms; but the time and space which he obtained to collect such treasure from the poverty of the East was industriously employed in the preparations of a bold and desperate attack. THE AWAKENING OF HERACLIUS [Sidenote: [616-622 A.D.]] Of the characters conspicuous in history, that of Heraclius is one of the most extraordinary and inconsistent. In the first and the last years of a long reign, the emperor appears to be the slave of sloth, of pleasure, or of superstition, the careless and impotent spectator of the public calamities. But the languid mists of the morning and evening are separated by the brightness of the meridian sun: the Arcadius of the palace arose the Cæsar of the camp; and the honour of Rome and Heraclius was gloriously retrieved by the exploits and trophies of six adventurous campaigns. It was the duty of the Byzantine historians to have revealed the causes of his slumber and vigilance. At this distance we can only conjecture, that he was endowed with more personal courage than political resolution; that he was detained by the charms, and perhaps the arts, of his niece Martina, with whom, after the death of Eudocia, he contracted an incestuous marriage; and that he yielded to the base advice of the counsellors, who urged as a fundamental law that the life of the emperor should never be exposed in the field. Perhaps he was awakened by the last insolent demand of the Persian conqueror; but at the moment when Heraclius assumed the spirit of a hero, the only hopes of the Romans were drawn from the vicissitudes of fortune which might threaten the proud prosperity of Chosroes, and must be favourable to those who had attained the lowest period of depression.
