Jones ingeniously makes use of the similarities which have been thought to exist between the American and Egyptian pyramids, and architecture generally, to prove his Tyrian theory. The general character of the American architecture is undoubtedly Egyptian, he argues; but the resemblance is not close enough in detail to allow of its being actually the work of Egyptian hands; the ancient cities of America were therefore built by a people who had a _knowledge_ of Egyptian architecture, and enjoyed constant intercourse with that nation. But some of the ruins are Greek in style; the mysterious people must also have been familiar with Greek architecture. Where shall we find such a people? The cap exactly fits the Tyrians, says Mr Jones, let them wear it. Unfortunately, however, Mr Jones manufactures the cap himself and knows the exact size of the head he wishes to place it on. He next goes on to prove "almost to demonstration that Grecian artists were authors of the sculpture, Tyrians the architects of the entire edifices,--while those of Egypt were authors of the architectural bases." The tortoise is found sculptured on some of the ruins at Uxmal; it was also stamped upon the coins of Grecian Thebes and Ægina. From this fact it is brought home at once to the Tyrians, because the Phœnician chief Cadmus, who founded Thebes, and introduced letters into Greece, without doubt selected the symbols of his native land to represent the coin of his new city. The tortoise is, therefore, a Tyrian emblem.[I-149] The American ruins in some places bear inscriptions written in vermilion paint; the Tyrians were celebrated for a purple dye. Carved gems have been found in American tombs; the Tyrians were also acquainted with gem-carving. The door-posts and pillars of Solomon's temple were square;[I-150] square obelisks and columns may also be found at Palenque. But it is useless to multiply quotations; the absurdity of such reasoning is blazoned upon the face of it. At Dighton, on the bay of Narraganset, is, or was, an inscription cut in the rock, which has been confidently asserted to be Phœnician. Copies of this inscription have been frequently made, but they differ so materially that no two of them would appear to be intended for the same design.[I-151] [Sidenote: INSCRIBED TABLETS.] In the mountains which extend from the village of Uruana in South America to the west bank of the Caura, in 7° lat., Father Ramon Bueno found a block of granite on which were cut several groups of characters, in which Humboldt sees some resemblance to the Phœnician, though he doubts that the worthy priest whose copy he saw performed his work very carefully.[I-152]
