(4) Even such a tax was less intolerable than the privilege of monopolies, which checked the fair competition of industry, and, for the sake of a small and dishonest gain, imposed an arbitrary burden on the wants and luxury of the subject. “As soon,” says Procopius,[e] “as the exclusive sale of silk was usurped by the imperial treasurer, a whole people, the manufacturers of Tyre and Berytus, was reduced to extreme misery, and either perished with hunger, or fled to the hostile dominions of Persia.” A province might suffer by the decay of its manufactures; but in this example Procopius has partially overlooked the inestimable benefit which the empire received from Justinian’s introduction of silk-culture. His addition of one-seventh to the ordinary price of copper money may be interpreted with the same candour; and the alteration, which might be wise, appears to have been innocent; since he neither alloyed the purity nor enhanced the value of the gold coin, the legal measure of public and private payments. (5) The ample jurisdiction, required by the farmers of the revenue to accomplish their engagements, might be placed in an odious light, as if they had purchased from the emperor the lives and fortunes of their fellow-citizens. And a more direct sale of honours and offices was transacted in the palace, with the permission, or at least with the connivance, of Justinian and Theodora. The claims of merit, even those of favour, were disregarded; and it was almost reasonable to expect that the bold adventurer, who had undertaken the trade of a magistrate, should find a rich compensation for infamy, labour, danger, the debts which he had contracted, and the heavy interest which he paid. A sense of the disgrace and mischief of this venal practice at length awakened the slumbering virtue of Justinian; and he attempted, by the sanction of oaths and penalties, to guard the integrity of his government: but at the end of a year of perjury, his rigorous edict was suspended, and corruption licentiously abused her triumph over the impotence of the laws.
