COSA.

[chap. XI.VII.

other hand it may be said, that this rectangular masonry-
is but the natural finishing off of the polygonal, just as the
latter generally runs into the horizontal at angles, as may
be observed in the gates and towers of this same city.6

Prom the ramparts you may perceive that the walls
fall back in some degree, though never so much as in a
modern revStement, but the towers are perpendicular on
every side, save in a few cases where the masonry is
dislocated, and they topple over.7

Of gates there is the orthodox number of three ; one in
the centre of the northern, southern, and eastern walls of
the city respectively.8 They are well worthy of attention,
all of them being double, like the two celebrated gateways
of Volterra, though without even the vestige of an arch.
The most perfect is that in the eastern wall, which is
represented in the woodcut at the head of this chapter.9

6 These features are shown in the
woodcut at the head of this Chapter,
which represents the eastern gate of
Cosa. The masonry, though decidedly
polygonal, appears in the door-post of
the gate to be rectangular. In the
fragment of walling to the left, the
blocks are polygonal below, and regular
above, or at least laid in horizontal
courses. The manner in which small
pieces were fitted into the interstices
is also shown. But the peculiarities of
the masonry are not so striking in this,
as in many other portions of the forti-
fications. It was selected from several
sketches, as illustrative also of the gate.
On this side of the city the masonry is
smaller than on the others. The largest
of the blocks in the woodcut is not
more than 4 feet square, and the height
of the wall is only 15 or 16 feet.

7 The bastion and round tower of
Norba, on the contrary, narrow up-
wards considerably.

8 There may have been a postern in

the south-eastern angle of the walls, at
the spot marked 2 in the Plan. Sir R.
C. Hoare also thought he could perceive
four gates; and he speaks of four ancient
roads. Classical Tour, I. p. 58.

9 Its entrance is about 12 feet wide,
but the passage within is double that in
width and 28 feet long ; the inner gate
is no longer standing, though indications
of it are traceable. The depth of the
outer doorposts, or in other words the
thickness of the wall, is 7 feet, 8 inches.
Gateways on a similar plan are found
in the Cyclopean cities of Latium—the
Porta di S. Francesco at Alatri, and
the Porta Cassamara at Ferentino for
instance ; the latter however is proba-
bly of Roman construction.

The gates of Cosa, unlike those of
Volterra, do not exemplify the precepts
of Vitruvius (I. 5), that the road to a
gateway should be so arranged, that the
approaching foe should have his right
side, or that unprotected by his shield,
open to the attacks of the besieged.
