Etruscan. The construction of its gates might be cited as
an objection. There are seven of these, the largest in the
centre,—all with flat architraves composed of cuneiform
blocks holding together on the principle of the arch, though
without cement; as is proved in one gateway, where, the
masonry being dislocated, the keystone has slipt down
several inches, yet is still supported by the contiguous
blocks.9 This mode of construction, like the arch itself,
has generally been supposed a Roman invention; but
there is now little doubt that the arch in Italy had an
Etruscan origin, and that the Romans derived it from
Etruria; therefore, seeing the perfection to which the
arched vault had been brought at a very early age in the
Cloaca Maxima, there is nothing in the peculiar style,
or difficult construction of this flat arch which mflitates
against its being of Etruscan formation; for the principle
of cuneiform sustentation once discovered, the progress

short and easy.-
