chap, xxxiii.] HIGH ANTIQUITY OF THIS TOMB. 47
The similarity of the structure to the Cyclopean gallery
at Tiryns is striking; the masonry, it is true, is far less
massive, but the style is identical, showing a rude attempt
at an arch, the true principle of -which had yet to be dis-
covered. It is generally admitted, not only that such a
mode of construction must be prior to the discovery of the
perfect arch, but that every extant specimen of it must
have preceded the knowledge of the correct principle. It
is a mode not peculiar to one race, or to one age, or the
result of a particular class of materials, but is the expedient
naturally adopted in the formation of arches, vaults, and
domes, by those who are ignorant of the cuneiform prin-
ciple ; and it is therefore to be found in the earliest
structures of Egypt, Greece, Italy, and other parts of the
Old World, as well as in those of the semi-civihsed races of
the New.6 The Cloaca Maxima, which is the earliest
known instance of the perfect arch in Italy, dates from the
days of the Tarquins; this tomb then must be considered
as of a remoter period, coeval at least with the earliest
days of Rome—prior, it may be, to the foundation of the
City.7
