    There is no absolute proof that the Israelites employed arches
    in their buildings. The arch was employed in the building of the
    pyramids of Egypt. The oldest existing arch is at Thebes, and
    bears the date B.C. 1350. There are also still found the remains
    of an arch, known as Robinson's Arch, of the bridge connecting
    Zion and Moriah. (See TYROPOEON VALLEY.)
