If the journey be made on a market or fair day, the space between the walls and the station at Arezzo may be seen crowded with white oxen, suggesting the thought of triumphs and triumphal sacrifices. Their race, it was said, prayed to the gods that Marcus and Julian might not win victories which would lead to their destruction. And the prayer seems to have been answered, as the breed specially connected with Clitumnus has clearly not died out, even by the banks of Clanis. The journey is not a long one; yet, if we had time to see everything, we might well wish to break it, as we pass by the hill of Castiglione Fiorentino, with its walls and towers. That strong and stern hill-fortress comes in well between Arezzo and Cortona. Arezzo covers a hill, but it can hardly be said to stand on a hill-top; Castiglione distinctly does stand on a hill-top; Cortona sits enthroned on a height which it would hardly be straining language to speak of as a mountain. We have now come to a site of the oldest class, the stronghold on the height, like Akrokorinthos and the Larissa of Argos. But at Argos and Corinth the mountain-fortress became, at a later stage, the citadel of the younger city which grew up at the mountain's foot. But at Cortona, as at greater Perugia, the city still abides on the height; it has never come down into the plain. So it has remained at Laon; so it has become at Girgenti, where the vast lower space of the later Akragas is forsaken, and the modern town has shrunk up within the lines of the ancient acropolis. From the ground below Cortona we look up to a city like those of old, great and fenced up to heaven; the "diadem of towers" is there still, though it is now made up of a group of towers, ecclesiastical, municipal, and military, none of them of any account in itself, but each of which joins with its fellows to make up an effective whole. At Cortona indeed, as at Argos and Corinth, there is an upper and a lower city, and the upper city is pretty well forsaken. But while at Argos and Corinth the lower city stands in the plain, and the acropolis soars far above it, at Cortona the lower city itself stands so high up the hill that it is only when we reach it that we fully understand that there is a higher city still. The site itself belongs so thoroughly to the oldest days of our European world that there is a certain kind of satisfaction in finding that the main interest of the place belongs to those oldest days. We are well pleased that everything of later times is of quite a secondary character, and that the distinctive character of Cortona is to be the city of the Etruscan walls.
