There is a tradition, that the palaces of the kings of Alba stood on a rock; and so near to the edge of the precipice, that when the impiety of one of its monarchs provoked Jupiter to strike it with his lightning, a part of the mass was precipitated into the lake, carrying the impious king along with the ruins of his habitation. This tradition is apparently confirmed by a singular feature in a part of the remains of this city; for, directly under the rock of the citadel, toward the lake, and where the palace, both for security and prospect, would have been placed, is a cavern, fifty feet in depth, and more than one hundred in width; a part of the roof of which has evidently fallen in, and some of the blocks still remain on the spot[9]. NO. VII.--ALCANTARA. This town (in Spain) was built by the Moors, who gave it the name it bears; which, in the Moorish language, signifies a bridge; and this bridge shows that the original city belonged to the Romans in the time of Trajan; for on one of the arches is this inscription:-- IMP. CAESARI, D. NERVAE, F. NERVAE. TRAIANO. AVG. GERM. DACICO. PONT. MAX. TRIB. POTEST. VIII. IMP. VI. COS. V. P.P. Formerly there were four pieces of marble, fixed in the walls of the bridge; in each of which there was an inscription, containing the names of the several towns and districts, that contributed towards the expense of making it. Three of these marbles are lost; but the fourth remains, and bears the following inscription:-- MVNICIPIA. PROVINCIAE. LVSITAN. STIPE. CONFLATA. QVAE. OPVS. PONTIS. PERFECERVNT. IGAEDITANI LANCIENSES. OPIDANI. TALORI. INTERAMNIENSES. COLARNI. LAOCIENSES. TRANSCVDANI. ARAVI. MEIDVBRIGENSES. ARABRIGENSES. BANIENSES. PAESVRES. At the entrance of the bridge there is a small temple, cut in the rock, by the same person that built the bridge. The roof of this temple consists of two large stones. In the temple there is an inscription to the following effect:--"_It is reasonable to imagine, that every one, that passes this way, would be glad to know the name of the person that built this bridge and temple; and with what intent they were made, by cutting into this rock of the Tagus, full of the majesty of the Gods, and of Cæsar, and where art showed itself superior to the tough and stubborn matter that resisted her. Know, then, that it was that noble architect Lacer, who built this bridge, which will last as long as the world. Lacer, having finished this noble bridge, made and dedicated this new temple, with sacrifices, to the gods, in hopes of rendering them propitious to him, for having honoured them after this manner. This temple he dedicated to the gods of Rome, and to Cæsar; looking upon himself to have been extremely fortunate, in having been able to make so just and proper a sacrifice._[10]" NO.
