CHAP. 8.—AT WHAT PERIOD THE VARIOUS KINDS OF MARBLE CAME INTO USE AT ROME.
M. Lepidus, who was consul with Q. Catulus, was the first to have the lintels of his house made of Numidian marble, a thing for which he was greatly censured: he was consul in the year of Rome, 676. This is the earliest instance that I can find of the introduction of Numidian marble; not in the form of pillars, however, or of slabs, as was the case with the marble of Carystus, above-mentioned, but in blocks, and that too, for the comparatively ignoble purpose of making the thresholds of doors. Four-years after this Lepidus, L. Lucullus was consul; the same person who gave its name, it is very evident, to the Lucullan marble; for, taking a great fancy to it, he introduced it at Rome. While other kinds of marble are valued for their spots or their colours, this marble is entirely black.[2493] It is found in the island of Melos,[2494] and is pretty nearly the only marble that has taken its name from the person who first introduced it. Among these personages, Scaurus, in my opinion, was the first to build a theatre with walls of marble: but whether they were only coated with slabs of marble or were made of solid blocks highly polished, such as we now see in the Temple of Jupiter Tonans,[2495] in the Capitol, I cannot exactly say: for, up to this period, I cannot find any vestiges of the use of marble slabs in Italy.
CHAP. 9.—THE METHOD OF CUTTING MARBLE INTO SLABS. THE SAND USED IN CUTTING MARBLE.
But whoever it was that first invented the art of thus cutting marble, and so multiplying the appliances of luxury, he displayed considerable ingenuity, though to little purpose. This division, though apparently effected by the aid of iron, is in reality effected by sand; the saw acting only by pressing upon the sand within a very fine cleft in the stone, as it is moved to and fro.
The[2496] sand of Æthiopia is the most highly esteemed for this purpose; for, to add to the trouble that is entailed, we have to send to Æthiopia for the purpose of preparing our marble—aye, and as far as India even; whereas in former times, the severity of the Roman manners thought it beneath them to repair thither in search of such costly things even as pearls! This Indian sand is held in the next highest degree of estimation, the Æthiopian being of a softer nature, and better adapted for dividing the stone without leaving any roughness on the surface; whereas the sand from India does not leave so smooth a face upon it. Still, however, for polishing marble, we find it recommended[2497] to rub it with Indian sand calcined. The sand of Naxos has the same defect; as also that from Coptos, generally known as “Egyptian” sand.
