bonded with the other, and this may perhaps have been an addition or restoration of the emperor Claudius. The water re-appears from under an arch of rubble-work, which I do not take to be very ancient, and after washing all the dirty linen of Albano, runs off, as I have said, towards the Tiber. I have conducted you away from the lake, without mentioning to you a ruin which is here called the baths of Diana. It is composed of several parts, but the principal is a large vault, formed in an excavation in the slope of the hills. It is a delightful retreat on a hot day, and commands a beautiful view over the lake, though the richness of the vegetation immediately surrounding, hides the water too much. There are some remains, supposed to be of Thermæ, at Albano, which in certain points of view form a fine mass, but I did not see anything characteristic of their destination. Just out of the town, on the road to Naples, is a monument, which has been called the tomb of the Curiatii, but it now seems rather the fashion to consider it a monument erected to Pompey. Nibby thinks it the sepulchre of Aruns, the son of Porsenna, who lost his life in an unsuccessful attack on Aricia; and attributes another tomb to Pompey, at the opposite end of Albano, which appears to have been a tower of three stories in height, cased with marble. His chief argument for each is, that he has found no testimony to the contrary among the ancient writers. Amongst other proofs that the edifice in question is the tomb of Aruns, he quotes Varro’s description of the tomb of Porsenna, as given by Pliny. This appears to have had some resemblance to the present monument, and gives a colour to suppose it an Etruscan edifice, but does not at all connect it with Aruns. It consists of a square basement, supporting five cones, one at each angle, and a larger one in the middle. The masonry is of rubble, formed of fragments of peperino bedded in mortar, and the outside has been covered with large square blocks of peperino. If it be really Etruscan, it would serve to shew that the Romans derived their usual mode of building, _i. e._ a rubble mass cased with squared stones or bricks, from that people. Farther on, we find the old Appian way, now no longer used, supported to a considerable height, on a wall built of peperino; and in its neighbourhood, some vestiges of the ancient Aricia; the modern town is placed above it.
