CAVE
DI CUSA
Not
far from Selinunte, the Cusa quarries were the main source of building
stone for the town’s temples and, more specifically, given
the size of the blocks of stone extracted, for Temple G. The stone,
a fine-grained and resistant kind of tufa particularly suitabie
far building, was quarried for more than 150 years, since the first
half of the 6C BC. Work at the quarry ground to a brief halt following
the outbreak of war when Selinunte was forced to confront the Carthaginian
onslaught (resulting in the destruction of the town). The quarries
were abandoned shortly after, as were the houses
of the people who worked there. This is what is so unusual about
the place: enormous blocks of rock destined for the temples still
lie here half-quarried. The considerable number of such blocks makes
it possible to calculate that there must have been about 150 stone-cutters
engaged there.
The quarrying technique was long
and complex. Once the dimensions and profile of the piece to be
extracted had been marked out, a double groove about half a metre
deep was dug around it to enable the stonemasons to work more easily
(the so-called chipping channel). The block was worked in situ and
cut straight from the base rock. The tools used included picks,
bronze saws and wedges. To split the harder layers, wooden wedges
were inserted into cracks and then dampened with water so that,
as they swelled, the stone would crack open. Once this was done,
the block was severed at the base. The lighter blocks were removed
by means of winches while the bulkier ones were slid down ramps
(in this case, the material in front of the block was removed).
The deep U-shaped grooves visible in some of the square blocks were
made so that a rope could be fed through them for lifting (some
can be seen at Agrigento in the Temple of Jupiter). Many blocks
have a square hole at either end. Into these sockets were fitted
special shafts that enabled the blocks to be moved and set in place.
The blacks were transported on wooden frames with wheels, and pulled
by oxen and slaves. A wide rocky track 12km long led from the quarries
to Selinunte.
The
modern name of the quarries comes from the owner of the land on
which they were discovered.
QUARRY
Signposted
(3km) to the south of Campobello di Mazara.
The great cylindrical blacks which
lie scattered on the ground or await to be quarried (some 60 in
number) are a characteristic feature of the quarry, which is 1.8km
long and extends along a ridge from east to west.
In the first section of the quarry,
some blocks sit cut and ready for transporting; others barely sketched
out, are ready for the stone-cutter. At the far end of the quarry
is a capital in the making. Its cylindrical mass tapering from a
square base into the 12 wedges intended as the echinus or ovaio
moulding below the abacus. The cracks still show the marks made
by picks.
At Selinunte (see SELINUNTE), among
the ruins of Temple A, are examples of finished capitals with square
bases, complete with the top of the column shaft and a section of
the ovolo moulding intended as part of the entablature. |
