Incidents of Travel in Yucatan, Vol. I.

It may now be interesting to inquire if any similarity exists between the American method and those observed among the nations of antiquity in Europe and Asia. A true arch is formed of a series of wedge-like stones or of bricks, supporting each other, and all bound firmly together by the pressure of the centre one upon them, which latter is therefore distinguished by the name of keystone.

It would seem that the arch, as thus defined, and as used by the Romans, was not known to the Greeks in the early periods of their history, otherwise a language so copious as theirs, and of such ready application, would not have wanted a name properly Greek by which to distinguish it. The use of both arches and vaults appears, however, to have existed in Greece previous to the Roman conquest, though not to have been in general practice. And the former made use of a contrivance, even before the Trojan war, by which they were enabled to gain all the advantages of our archway in making corridors or hollow galleries, and which, in appearance, resembled the pointed arch, such as is now termed Gothic. This was effected by cutting away the superincumbent stones at an angle of about 45° with the horizon.

Of the different forms and curves of arches now in use, the only one adopted by the Romans was the semicircle; and the use of this constitutes one leading distinction between Greek and Roman architecture, for by its application the Romans were enabled to execute works of far bolder construction than those of the Greeks: to erect bridges and aquæducts, and the most durable and massive structures of brick. On the antiquity of the arch among the Egyptians, Mr. Wilkinson has the following remarks: "There is reason to believe that some of the chambers in the pavilion of Remeses III., at Medeenet Haboo, were arched with stone, since the devices on the upper part of their walls show that the fallen roofs had this form. At Saggara, a stone arch still exists of the time of the second Psamaticus, and, consequently, erected six hundred years before our era; nor can any one, who sees the style of its construction, for one moment doubt that the Egyptians had been long accustomed to the erection of stone vaults. It is highly probable that the small quantity of wood in Egypt, and the consequent expense of this kind of roofing, led to the invention of the arch. It was evidently used in their tombs as early as the commencement of the eighteenth dynasty, or about the year 1540 B.C.; and, judging from some of the drawings at Beni Hassan, it seems to have been known in the time of the first Osirtasen, whom I suppose to have been contemporary with Joseph."—Manners and Customs of the Anc. Egyptians, vol. ii., p. 116, 117, 1st series.

The entrance to the great Pyramid at Gizeh is somewhat similar in form to the arches found in Yucatan; it consists of two immense granite stones of immense size, meeting in a point and forming a sharp angle.

Of the accompanying plates, No. 2 represents the arches in the walls of Tiryns, copied from Sir W. Gell's Argolis; No. 3, an arch (called Cyclopean) at Arpino, in the Neapolitan Territory; No. 4, the most common form of arch used by the ancient American builders. A striking resemblance will doubtless be observed, indeed, they may almost be considered identical; and it may be added, that at Medeenet Haboo, which forms a part of the ancient Egyptian Thebes, a similar contrivance was observed by Mr. Catherwood. From this it will appear that the true principles of the arch were not understood by the ancient Egyptians, Greeks, or Etruscans, or by the American builders. It might be supposed that a coincidence of this strongly-marked character would go far to establish an ancient connexion between all these people; but, without denying that such may have been the case, the probabilities are greatly the other way.

This most simple mode of covering over a void space with stone, when single blocks of sufficient size could not be employed, would suggest itself to the most barbarous as well as to the most refined people. Indeed, in a mound lately opened in the Ohio Valley, two circular chambers were discovered, and are still preserved, the walls being made of logs, and the roofs formed by overlapping stones rising to a point, on precisely the same plan as the Treasury of Atreus at Mycenæ, and the chamber at Orchomenus, built by Minyas, king of Bœotia. No inference as to common origin or international communication can with safety be drawn from such coincidences, or from any supposed coincidence between the pyramidal structures of this Continent and those of Egypt, for no agreement exists, except that both are called pyramids.
