It is impossible to justify the vain and credulous exaggerations of modern travellers, who sometimes stretch the limits of Constantinople over the adjacent villages of the European, and even of the Asiatic coast. But the suburbs of Pera and Galata, though situate beyond the harbour, may deserve to be considered as a part of the city, and this addition may perhaps authorise the measure of a Byzantine historian, who assigns sixteen Greek (about fourteen Roman) miles for the circumference of his native city. Such an extent may seem not unworthy of an imperial residence. Yet Constantinople must yield to Babylon and Thebes, to ancient Rome, to London, and even to Paris.
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 labour, 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 about £2,500,000 [$12,500,000] for the construction of the walls, the porticoes, 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 harbour of Byzantium. A multitude of labourers 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 defence 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 much enthusiasm that nothing seemed wanting except the souls of the illustrious men whom those 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.
