One thing is plain, that the builders of the walls of Anagnia, like the builders of the _cloaca_ at Rome, but most unlike the elder builders of Cora and Signia, knew as well as any men how to turn arches. On the highest point of the town, by the modern gate which looks out towards Ferentino, within the circuit of the ancient _arx_, we may still see, blocked, partly hidden by the modern gate, disguised by the arrangements of the mediæval castle, the double gate of the ancient wall. It is perfectly plain, but with arches thoroughly well turned, with a double range of voussoirs. A smaller arch of the same workmanship beside them looks almost as if it had been blocked from the beginning. The _arx_ itself, it should be remembered, had its separate wall within that of the city, a noble fragment of which, of exactly the same character as the town wall, is still to be seen in a narrow street a little lower down. When we actually reach Anagni, there can be no doubt that the character in which it chiefly strikes us is that of the city of the Hernican walls, if Hernican walls we may call them. But historically Anagni is so far more famous as the city of mediæval Popes that it is fitting that it should have something to show in that character also. The town is rich in mediæval fragments. The main street, in its winding courses, displays long ranges of blocked arcades, round and pointed, which, when open, must have given it, narrow and often dim as it is, no small measure of stateliness. Not a few buildings stand out with arches of vast height and boldness, suggesting, as it is fit that one papal city should suggest to another, the mighty works of Rome's absent Bishops at Avignon. Not remarkable for height, but most remarkable for their span, are the exceedingly bold arches which support the communal palace, once, it is said, the dwelling of the Popes, a building which, on its northern side, shows a range of windows which savour of France or England rather than of Italy. The houses with their staircases often present highly picturesque shapes, which in one house in the main street, where the outside staircase is sheltered by two arches resting on a graceful column, grow into a form of genuine beauty. And an elegant form of double window, two round arches divided by a slender shaft, is characteristic of the architecture of Anagni. It is needless to add that at Anagni, as everywhere else in Italy, most of these relics of the skill of former times have been mercilessly disfigured and mutilated.
