The master of the Roman world, who aspired to erect an eternal monument of the glories of his reign, could employ in the prosecution of that great work the wealth, the labor, and all that yet remained of the genius of obedient millions. Some estimate may be formed of the expense bestowed with imperial liberality on the foundation of Constantinople, by the allowance of [Pg 6288] about two millions five hundred thousand pounds for the construction of the walls, the porticos, and the aqueducts. The forests that overshadowed the shores of the Euxine, and the celebrated quarries of white marble in the little island of Proconnesus, supplied an inexhaustible stock of materials, ready to be conveyed, by the convenience of a short water carriage, to the harbor of Byzantium. A multitude of laborers and artificers urged the conclusion of the work with incessant toil; but the impatience of Constantine soon discovered that, in the decline of the arts, the skill as well as numbers of his architects bore a very unequal proportion to the greatness of his designs. The magistrates of the most distant provinces were therefore directed to institute schools, to appoint professors, and by the hopes of rewards and privileges to engage in the study and practice of architecture a sufficient number of ingenious youths who had received a liberal education. The buildings of the new city were executed by such artificers as the reign of Constantine could afford; but they were decorated by the hands of the most celebrated masters of the age of Pericles and Alexander. To revive the genius of Phidias and Lysippus surpassed indeed the power of a Roman emperor; but the immortal productions which they had bequeathed to posterity were exposed without defense to the rapacious vanity of a despot. By his commands the cities of Greece and Asia were despoiled of their most valuable ornaments. The trophies of memorable wars, the objects of religious veneration, the most finished statues of the gods and heroes, of the sages and poets of ancient times, contributed to the splendid triumph of Constantinople, and gave occasion to the remark of the historian Cedrenus, who observes with some enthusiasm that nothing seemed wanting except the souls of the illustrious men whom these admirable monuments were intended to represent. But it is not in the city of Constantine, nor in the declining period of an empire, when the human mind was depressed by civil and religious slavery, that we should seek for the souls of Homer and of Demosthenes.
