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.
