Virgil showed himself a true artist in bringing his hero up the Tiber, which in his day was freely used for navigation up to and even above the city. He saw that by the river alone he could land him exactly where he could be shown by his friendly host, almost at a glance, every essential feature of the site, every spot most hallowed by antiquity in the minds of his readers. Rowing up the river, which graciously slackened its swift current, Aeneas presently caught sight of the walls and citadel, and landed just beyond the point where the Aventine hill falls steeply almost to the water's edge. Here in historical times was the dockyard of Rome; and here, when the poet was a child, Cato had landed with the spoils of Cyprus, as the nearest point of the river for the conveyance of that ill-gotten gain to the treasury under the Capitol.[3] Virgil imagines the bank clothed with wood, and in the wood--where afterwards was the Forum Boarium, a crowded haunt--Aeneas finds Evander sacrificing at the Ara maxima of Hercules, of all spots the best starting-point for a walk through the heart of the ancient city. To the right was the Aventine, rising to about a hundred and thirty feet above the river, and this was the first of the hills of Rome to be impressed on the mind of the stranger, by the tale of Hercules and Cacus which Evander tells his guest. In front, but close by, was the long western flank of the Palatine hill, where, when the tale had been told and the rites of Hercules completed, Aeneas was to be shown the cave of the Lupercal; and again to the left, approaching the river within two hundred yards, was the Capitol to be: Hinc ad Tarpeiam sedem et Capitolia ducit, Aurea nunc, olim silvestribus horrida dumis. Below it the hero is shown the shrine of the prophetic nymph Carmenta, with the Porta Carmentalis leading into the Campus Martius; then the hollow destined one day to be the Forum Romanum, and beyond it, in the valley of the little stream that here found its way down from the plain beyond, the grove of the Argiletum. Here, and up the slope of the Clivus sacer, with which we shall presently make acquaintance, were the lowing herds of Evander, who then takes his guest to repose for the night in his own dwelling on the Palatine, the site of the most ancient Roman settlement.[4]
