This theory is confirmed by discoveries in the prehistoric cemeteries of the Viminal and Esquiline hills, which contain coffins as well as cineraria, or ash-urns. The discoveries have been published only in a fragmentary way, so that we cannot yet follow their development stage by stage, and determine at what periods and within what limits the influence of more civilized neighbors was felt by the primitive dwellers upon the Seven Hills. One thing is certain; the race that first colonized the Campagna was buried in trunks of trees, hollowed inside and cut to measure, as is the custom among some Indian tribes of the present day. In March, 1889, the engineers who were attending to the drainage of the Lago di Castiglione--the ancient Regillus--discovered a trunk of _quercus robur_, sawn lengthways into two halves, with a human skeleton inside, and fragments of objects in amber and ivory lying by it. The coffin, roughly cut and shaped, was buried at a depth of fourteen feet, in a trench a trifle longer and larger than itself, and the space between the coffin and the sides of the trench was filled with archaic pottery, of the type found in our own Roman necropolis of the Via dello Statuto. There were also specimens of imported pottery, and a bronze cup. The tomb and its contents are now exhibited in the Villa di Papa Giulio, outside the Porta del Popolo. When Rome was founded, this semi-barbaric fashion of burial was by no means forgotten or abandoned by its inhabitants. We have not yet discovered coffins actually dug out of a tree, but we have found rude imitations of them in clay. These belong to the interval of time between the foundation of the city and the fortifications of Servius Tullius, having been found at the considerable depth of forty-two feet below the embankment of the Servian wall, in the Vigna Spithoever. They are now exhibited in the Capitoline Museum (Palazzo dei Conservatori), together with the skeletons, pottery, and bronze _suppellex_ they contained. Nearly every type of tomb known in Etruria, Magna Græcia, and the prehistoric Italic stations has a representative in the old cemeteries of the Viminal and the Esquiline. There are caves hewn out of the natural rock, with the entrance sealed by a block of the same material; in these are skeletons lying on the funeral beds on either side of the cave, or even on the floor between them, with the feet turned towards the door, and Italo-Greek pottery, together with objects in bronze, amber, and gold. There are also artificial caves, formed by horizontal courses of stones which project one beyond another, from both sides, till they meet at the top. Then there are bodies protected by a circle of uncut stones; others lying at the bottom of wells, and finally regular sarcophagi in the shape of square huts, and cineraria like those described on page 29 of my "Ancient Rome."
