In truth, a certain degree of wonder is awakened by the fact that Cortona exists at all. It would have been by no means amazing if we had found only its ruins, as on so many other old-world sites for which later times have found no use. Great in its earliest days, foremost among the Etruscan cities of the mountains, Cortona has never been great in any later age. As a Roman city and colony it was of so little account that, even in Italy, where bishops are so thick upon the ground, it did not become a bishopric till the fourteenth century. Just at that time came its short period of anything like importance among the cities of mediæval Italy. Sold to Florence early in the fifteenth century, it has ever since followed the fortunes of the ruling city. Yet through all these changes Cortona has managed to live on, though we can hardly say to flourish. It still keeps the character of a city, though a small and mean one, inhabited by a race of whom the younger sort seem to have nothing to do but to run after the occasional visitor. One ragged urchin offers to accompany him to the cathedral; another persists in following him round nearly the whole circuit of the ancient walls. This last is too bad; a walk round the walls of Cortona is emphatically one of those things which are best enjoyed in one's own company. As an Italian city which has lived, though in rather a feeble way, through the regular stages of Roman colony and mediæval commonwealth, Cortona has of course its monuments which record those periods of its being. There are some small fragments of Roman work, but nothing that can be called a Roman building. There is a crowd of churches and monasteries, but none of any great architectural value, though some contain works of importance in the history of painting. It perhaps marks the position of Cortona as a comparatively modern bishopric that its cathedral church is in no sort the crowning building of the city. The _duomo_ stands about half-way up the height within the town, on a corner of the walls. Its elegant _Renaissance_ interior has been already spoken of; it seems to have supplanted a Romanesque building the columns of which may have been used again. The point in the upper city where we should have looked for the _duomo_ is occupied by the Church of St. Margaret, that is, Margaret of Cortona, described over her portal as "pœnitens Margarita," marked off thereby alike from the virgin of Antioch and from the matron of Scotland. The municipal buildings are not remarkable, though one wall of the Palazzo Pretorio must be a treasure-house for students of Italian heraldry, thickly coated as it is with the arms of successive _podestas_. Of private palaces the steep and narrow streets contain one or two; but it is not on its street architecture that Cortona can rest its claim to fame. From the lower city, with its labyrinth of streets, we may climb to the acropolis. Here, around the Church of St. Margaret, all seems desolate.
