As it would be impossible in this small book to give anything beyond a cursory sketch of all the different buildings of the town, we have decided to deal with the details of some of the principal ones, leaving the rest for the discovery of those whose leisure and intelligence will always make such exploration a delight. There is no lack of excellent guide-books to Perugia. Of the fuller and rarer ones we would mention those of Siepi and Orsini and the more modern one of Count Rossi Scotti. These are in Italian. Murray's last edition of "Central Italy" contains clear and excellent general information, and there are several small local guides--the best of these by Lupatelli--which can be had in the hotel. No one who really desires to study the town should fail to read the fascinating books of its best lover, Annibale Mariotti; and the works of Conestabile and Vermiglioli are invaluable for students. All these can be had in the public library of the town where there is a pleasant quiet room in which to study them, and the excessive courtesy of whose head--Count Vincenzo Ansidei--makes research an easy pleasure there. The topography of Perugia is simple: "The entire city," says Mariotti, "since the very earliest days, was divided into five quarters or _rioni_, which from the centre, that is to say, the highest point of the town, and with as gentle an incline as the condition of the ground allows, stretch out in five different directions like so many sunbeams across the mountain side. These gates are: _Porta Sole_ to the east, _Porta Susanna_ to the west (formerly called Trasimene), _Porta S. Angelo_ (formerly Porta Augusta) to the north, _Porta S. Pietro_ to the south, and _Porta Eburnea_ to the southwest. Each of these separate gates bears its own armorial design and colour. Porta Sole is white and bears a sun with rays; Porta Susanna blue, with a chain; Porta S. Angelo red, with a branch of arbutus; Porta S. Pietro yellow, with a balance, and Porta Eburnea green, with a pilgrim's staff."
