Now besides these products that mountain makes an earth, the peculiar nature of which I am going to describe. Since the fire has not the power of burning (for by its union with, the water all its blazing qualities are extinguished) but is still able to separate and melt the substances with which it comes in contact, it follows that the oily part of the earth is melted by it, whereas the hard and what I might call the bony part of it is left as it was. Hence the masses of earth necessarily become porous and when exposed to the dry air crumble into dust, but when they are placed in a swirl of water and sand grow into a solid piece; as much of them as is in the liquid hardens and petrifies. The reason for this is that the brittle element in them is disintegrated and broken up by the fire, which possesses, the same nature, but by the admixture of dampness is chilled, and so, being compressed all over, through and through, becomes indissoluble. Such is Baiae, where Agrippa as soon as he had constructed the entrances collected ships and rowers, of which he fortified the former with armor and trained the latter to row on wooden benches. [-52-] Now the population of Rome was being disturbed by signs. Among the various pieces of news brought to them was one to the effect that many dolphins battled with one another and perished near Aspis, the African city. And in the vicinity of the City blood descended from heaven and was smeared all about by the birds. When at the Ludi Romani not one of the senators was entertained on the Capitol, as had been the custom, they took this, too, as a portent. Again, the incident that happened to Livia caused her pleasure, but inspired the rest with terror. A white bird carrying a sprig of fruited laurel had been thrown by an eagle into her lap. As this seemed to be a sign of no small importance, she took care of the bird and planted the laurel. The latter took root and grew, so that it amply supplied those who were afterward to celebrate triumphs; and Livia was destined to hold Caesar's power in a fold of her robe and to dominate him in everything.
