It is proved (we submit) that the _Sculpture_ in many parts, and especially at Uxmal, partakes of the _Grecian_ character, while the _Architecture_ is that of the _Egyptian_. This is a nice distinction,--but it enables us to strengthen our belief that Egypt, as a Nation, could not have been the builders, but they must have been a People (we repeat it, to impress it on the mind of the reader) having a knowledge of the Nile and her edifices; to this may be joined, a People having a knowledge, also, of the Greeks, since the Sculpture at Uxmal is Grecian in design. The Tyrians possessed this intercourse;--but, it is possible that some few Greeks may have been of the Colony landing on "the American coast" before the Christian Æra,--that they may have gladly embraced the occasion, as the only means of escaping death at the fearful event which caused the Migration. From the same cause a few Egyptians may have escaped, and joined the colony in the same manner. The strangers on the Island of Tyrus, would probably be those who had arrived by water from a distance,--Egypt was one port of commerce, Ægina another, and ambitious of maritime fame. Ægina is selected for more than one reason. It was an Island in direct intercourse with Tyrus, and the Ægineans were renowned for their general knowledge of the art of ornamental Sculpture, but not on so grand a scale as that of Athens. The Ægineans were called _myrmidons_, or _emmets_, from their patient perseverance in the art of Agriculture and other employments,--and thence the _Tortoise_ became their National emblem, the slow but sure progress of that shellfish being a symbol of their industry; it formed a double emblem; viz., of their industry and marine character. Now it will be remembered that the Ruins of Uxmal display four _Tortoises_ in stone Sculpture,--and one was found detached, and buried in the Ruins of Copan.
