It is only seventeen years since the true point of commencement of the Appian Way was discovered. For a long time the Porta Capena by which it left Rome was supposed to be situated outside of the present walls, in the valley of the Almo. But Dr. Parker, at the period indicated, making some excavations in the narrowest part of the valley between the Coelian and Aventine hills, came upon some massive remains of the original wall of Servius Tullius, and in these he found the true site of the Porta Capena. This discovery, confirming the supposition of Ampere and others, cleared up much that was inexplicable in the topography of this part of Rome, and enabled antiquarians to fix the relative position of all the historical spots. The Via Appia is thus shown to have extended upwards of three-quarters of a mile within the present area of the city, over the space between the wall of Servius Tullius and the wall of Aurelian. And this is still further confirmed by the discovery, three hundred years ago, of the first milestone of the Appian Way in a vineyard, a short distance beyond the modern gate of St. Sebastian, marking exactly a Roman mile from that point to the site of Dr. Parker's discovery. This milestone now forms one of the ornaments on the balustrade at the head of the stairs of the Capitol. The Appian Way shared in the vicissitudes of the city. After the fall of the Western Empire, about the beginning of the sixth century, when it was finally repaired by Theodoric, it fell into desuetude. The people, owing to the unsettled state of the country, were afraid to move from home. A grievous apathy took possession of all classes; agriculture was neglected, and the drains being stopped up, the line of route was inundated, and the road, especially on the low levels, became quite impassable. For centuries it continued in this state, until it was overgrown with a marshy vegetation in the wet places, and covered with turf in the dry. About a hundred years ago Pope Pius VI. drained the Pontine Marshes, and restored other parts of the road, and made it available as the ordinary land-route from Rome to Naples. But it was left to Pio Nono to uncover the road between Rome and Albano, which had previously been confounded with the Campagna, and was only indicated by the double line of ruined tombs. After three years of hard work, and an expenditure of L3000, the part most interesting to the archaeologist--namely, from the third to the eleventh milestone--was laid bare, its monuments identified as far as possible, and a wall of loose stones built on both sides, to protect it from the encroachments of the neighbouring landowners. And now the modern traveller can walk or ride or drive comfortably over the very pavement which Horace and Virgil, Augustus and Paul traversed, and gaze upon the ruins of the very objects that met their eyes.
