No one, however, would contend that the position of Rome is an ideal one.  Taken in and by itself, without reference to Italy and the Mediterranean, that position has little to recommend it.  It is too far from the sea, nearly twenty miles up the valley of a river with an inconveniently rapid current, to be a great commercial or industrial centre; and such a centre Rome has never really been in the whole course of her history.  There are no great natural sources of wealth in the neighbourhood—­no mines like those at Laurium in Attica, no vast expanse of corn-growing country like that of Carthage.  The river too was liable to flood, as it still is, and a familiar ode of Horace tells us how in the time of Augustus the water reached even to the heart of the city.[9] Lastly, the site has never really been a healthy one, especially during the months of July and August,[10] which are the most deadly throughout the basin of the Mediterranean.  Pestilences were common at Rome in her early history, and have left their mark in the calendar of her religious festivals; for example, the Apolline games were instituted during the Hannibalic war as the result of a pestilence, and fixed for the unhealthy month of July.  Foreigners from the north of Europe have always been liable to fever at Rome; invaders from the north have never been able to withstand the climate for long; in the Middle Ages one German army after another melted away under her walls, and left her mysteriously victorious.

There are some signs that the Romans themselves had occasional misgivings about the excellence of their site.  There was a tradition, that after the burning of the city by the Gauls, it was proposed that the people should desert the site and migrate to Veii, the conquered Etruscan city to the north, and that it needed all the eloquence of Camillus to dissuade them.  It has given Livy[11] the opportunity of putting into the orator’s mouth a splendid encomium on the city and its site; but no such story could well have found a place in Roman annals if the Capitol had been as deeply set in the hearts of the people as was the Acropolis in the hearts of the Athenians.  At a later time of deep depression Horace[12] could fancifully suggest that the Romans should leave their ancient home like the Phocaeans of old, and seek a new one in the islands of the blest.  Some idea was abroad that Caesar had meant to transfer the seat of government to Ilium, and after Actium the same intention was ascribed to Augustus, probably without reason; but the third ode of Horace’s third book seems to express the popular rumour, and in an interesting paper Mommsen[13] has stated his opinion that the new master of the Roman world may really have thought of changing the seat of government to Byzantium, the supreme convenience and beauty of which were already beginning to be appreciated.[14]
