The town of Albano itself contains a good many antiquities, the most prominent among which, that which greets the eye on the entrance from Rome, is the huge tower-like pile, so cruelly stripped of its hewn stone, which, truly or falsely, passes for the tomb of Cnæus Pompeius Magnus. More striking on a close examination, though spoiled in its effect by a Papal freak of restoration, is the tomb which hovers between the names of Aruns son of Porsena and the Horatii and Curiatii. Which of the two would Sir George Lewis have looked on as the more impossible? This is the tomb which so singularly forestalled the outline of the Glastonbury kitchen--before its chimneys perished--and thereby of the Museum laboratory at Oxford. A good deal of the wall of the camp, a good deal of an amphitheatre on the hill-side, and several other fragments of the earlier Imperial time, are still to be seen. But after all Albano really exists, not for its own sake, but as a starting-point for the Alban lake and the Alban mount, and hardly less as a starting-point for ... the still glassy lake that sleeps Beneath Aricia's trees. Aricia has changed its site; the small modern town has flown up to the level of the _arx_, to be approached by Albano by almost the only work on which we do not grudge to see the name of Pius IX. The viaduct of that "Pontifex Optimus Maximus"--his votaries seem never quite to distinguish between him and Jupiter--is really a work worthy of Cæsars or consuls. Below it new Aricia has left the elder city, its fragments of walls and of the Appian Way, to be sought for in the valley below, the crater, so wise men tell us, of an extinct volcano, the biggest surely even in this region where craters meet us at every step. Scraps of primæval wall, hardly to be distinguished from the rocks, prepare us for what we are to see at places further out of the ordinary track; walls of the days of Sulla join on alike to what we have seen at Rome, and to what we are to see at Cori. But, after all, the "still glassy lake" to which the grove of the "rex nemorensis" has given the name of Nemi, is the true glory of Aricia. How well we remember being puzzled years and years ago with the thrilling run of the lines-- Those trees in whose dim shadow The ghastly priest doth reign, The priest who slew the slayer, And shall himself be slain. In these days the fault would be held to lie with the poet for venturing on an allusion which it might need a little research to take in. In those days we thought in such cases that the fault lay with ourselves; we admired without understanding till we lighted on the explanation which enabled us to understand as well. As such a process is a wholesome one, we will leave the lines without comment; not to speak of books of reference, the story will be found, in a somewhat grotesque form, in Dr. Merivale's chapter on the reign of Caius, better known as Caligula.
