The voice of history, which is often little more than the organ of hatred or flattery, reproaches Sapor with a proud abuse of the rights of conquest. We are told that Valerian, in chains, but invested with the Imperial purple, was exposed to the multitude, a constant spectacle of fallen greatness; and that whenever the Persian monarch mounted on horseback, he placed his foot on the neck of a Roman emperor. Notwithstanding all the remonstrances of his allies, who repeatedly advised him to remember the vicissitudes of fortune, to dread the returning power of Rome, and to make his illustrious captive the pledge of peace, not the object of insult, Sapor still remained inflexible. When Valerian sunk under the weight of shame and grief, his skin, stuffed with straw, and formed into the likeness of a human figure, was preserved for ages in the most celebrated temple of Persia; a more real monument of triumph, than the fancied trophies of brass and marble so often erected by Roman vanity. The tale is moral and pathetic, but the truth of it may very fairly be called in question. The letters still extant from the princes of the East to Sapor are manifest forgeries; nor is it natural to suppose that a jealous monarch should, even in the person of a rival, thus publicly degrade the majesty of kings. Whatever treatment the unfortunate Valerian might experience in Persia, it is at least certain that the only emperor of Rome who had ever fallen into the hands of the enemy, languished away his life in hopeless captivity.
