The princely prodigality of Trajan’s taste was defrayed by the plunder or the tribute of conquered enemies, and seems to have laid at least no extraordinary burden on his subjects. His rage for building had the further merit of being directed for the most part to works of public utility and interest. He built for the gods, the senate, and the people, and not for himself; he restored the palaces, enlarged the halls and places of public resort; but he was content himself with the palaces of his predecessors. A writer three centuries later declares of Trajan that he built the world over; and the wide diffusion and long continuance of his fame beyond that of so many others of the imperial series may be partly attributed to the constant recurrence of his name conspicuously inscribed on the most solid and best known monuments of the empire. The care of this wise and liberal ruler extended from the harbors, aqueducts, and bridges to the general repair of the highways of the empire. He was the great improver, though not the inventor of the system of posts on the chief roads, which formed a striking feature of Roman civilization as an instrument for combining the remotest provinces under a central organization. The legislation of this popular emperor is marked generally by a special consideration for Italian interests. The measures by which he secured a constant supply of grain from the provinces, exempting its exportation from all duties, and stimulating the growers at one extremity of the empire to relieve the deficiencies of another, were directed to the maintenance of abundance in Rome and Italy. Thus, on the casual failure of the harvest in Egypt, her empty granaries were at once replenished from the superfluous stores of Gaul, Spain, or Africa. Though Trajan’s mind did not rise to wide and liberal views for the advantages of the provinces, he neglected no favorable opportunity for the benefit of particular localities. His hand was open to bestow endowments and largesses, to relieve public calamities, to increase public enjoyments, to repair the ravages of earthquakes and tempests, to construct roads and canals, theatres and aqueducts. The activity displayed through the empire in works of this unproductive nature shows a great command of money, an abundant currency, easy means of transacting business, ample resources of labor, and well devised schemes of combining and unfolding them. Judicious economy went ever hand in hand with genuine magnificence.
