Even though we have known for some years now that several
Ancient Bronze Age settlements belonging to the facies of
Palma Campania (from the name of the site where the first
significant find in the facies was located) were destroyed
by an eruption of Somma and Vesuvius, we were far from imagining
how important the discovery of May 2001 in the immediate vicinity
of Nola would have been for the history of protohistoric architecture
and our knowledge of the Ancient Bronze Age. The exceptional
nature of this event and the clamour it aroused through the
attention paid to it by the media are due to the spectacular
state of conservation of the residential structures and the
enormous quantity of data brought to light by the excavation,
from the perfectly conserved marks left by cereals and animal
and vegetable remains to the objects and household structures
found on the site.
The village was identified during a normal building inspection
in a zone of significant archaeological interest, close to
the Torricelle necropolis and the amphitheatre, in an area
of roughly 1500 square metres set aside for a private construction
project, six metres from ground level. Three horseshoe-shaped
huts were found in the eastern part of the area surveyed,
separated from each other by stockades. In the remaining sector,
a number of fenced areas were identified, including a threshing
floor, inside which two wells were located. Some of the enclosures,
one of which included a clay cage built on a framework of
twigs beneath a canopy, were probably used for livestock,
due to the hoof marks of domestic animals found on the ground
there - cattle, sheep, goats and so on - often in combination
with human footprints. The animals escaped at the moment of
eruption, with the exception of nine goats, all around 4 months
pregnant, shut up in the cage, and four other she-goats tied
to the stockade. Other animals remained trapped too, including
an adult dog in one of the huts, found hidden behind the trellis
of a wall, where it had taken refuge.
The eruption
The human inhabitants also abandoned the village at the moment
of the eruption, leaving anything they were unable to carry
on the site. Unlike the situation that occurred in the nearby
villages, in Palma Campania and San Paolo Belsito, the nature
of the eruption gave the inhabitants sufficient time to make
their escape, while at the same time leaving the huts in a
perfect state of conservation. As the plain of Nola is at
the margin of the area where pyroclastic rock fell during
the first stage of the eruption, it escaped the shower of
white pumice that took place during the first 5 to 6 hours
of the catastrophe, suffering only the subsequent fall of
grey pumice and the flowing ash deposits that covered the
huts without causing them to collapse.
At the end of the eruption significant flooding took place,
bringing in materials to every part of the site, not only
inside the huts. As the huts are in any case located lower
down in the new ground level, they attracted mud. At this
point, a major event took place that led to the filling up
of the huts. This lahar effectively created resistance to
the inward collapse of the huts, providing a powerful counter-thrust
against the pumice that had built up outside them, enabling
the built structure to remain at a height of just over 1.3
metres. The mud flow slowly penetrated the structures, covering
over and filling the empty vessels and furnishings, such as
the oven, moving and raising up the lighter containers, restoring
and consolidating the precise form inside the huts of all
the materials found there, including a ladder and wooden vessels,
wickerwork containers, fabrics, cords from which some vessels
were hanging or which bound the structural elements together).
We can clearly make out the straw faggots that covered the
huts and ferns, oak leaves, mushrooms, the marks left by cereals
and other vegetable remains fossilised by the mud.
The excavation and its documentation
During the excavation, a large part of the outer covering
was removed to reveal the framework that supported it, with
the documentation of the significant structural elements.
To do this, both traditional (liquid plaster) and more modern
(silicon rubber) methods were used to fill the empty spaces
left by the construction material (wooden posts and beams,
ties, joints and so on). The precise nature of the photographic
and, more especially, graphic documentation, made it possible
to trace the tiniest details of the huts.
Using the same methods, at the levels of the pumice deposits
outside the huts, it was possible to identify the fencing
types - beams and/or trellises, poles, stakes, boards, and
so on - as well as a number of temporary structures, such
as a wooden bucket hanging from a fence.
In addition to the traditional excavation survey, a high precision,
three dimensional laser scanner detection technique was also
used, guaranteeing a very high level of scientific accuracy.
The appliance in question (Cyrax) makes use of an intermittent
laser beam which produces up to 1,000 separate points for
each vertical section and measures the transit time for each
point at considerable distances.
The scanner picks up four types of information for each point,
the x, y and z coordinates and the intensity of return, which
is shown by colour and grey tone mapping. The final result
of the operation is the real representation of the object
in the form of a cluster of points, whose density and precision
are equivalent to those of a photographic image that can be
measured. The clusters of points are then recorded and processed
using the most advanced graphic computer software.
The huts, furnishings and organisation of space
The residential structures (located in the NW-SE direction)
have a horseshoe shape with an opening in the straight part
and a protruding part over the entrance used as a canopy.
The dimensions are variable, as follows: hut 4: 15.6 m in
length, 4.6 m wide, 4.3/4.5 high; hut 3: 15.2 m long, 9 m
wide, 5 m high; hut 2: 7.5 m long, 4.5 m wide, 4.3/4.5 m high.
An inwardly opening door on the straight side near the south
wall gave access to the outside. This was made up of twigs
arranged horizontally, using a technique very similar to that
of the trellis.
The walls are continuous up to the roof, which has a much
steeper slope than that of the tiled canopies . They are built
using vertical poles located at roughly 0.4 m intervals, descending
to ground level, and horizontal wooden rails at a distance
of 0.25 m from each other. All these elements were bound to
each other with thick ropes. A number of axial poles supported
the roof. Other poles were arranged laterally, all around
the inner wall, and held up a vertical trellis consisting
of panels of wooden twigs and/or reeds laid out lengthways,
enabling the roof to disperse its weight. In this way, an
air space was formed between the trellis and the true wall,
used as an additional storage zone separated from the residential
sector. It is not impossible that there was a mezzanine in
at least one of the huts, where some of the large pottery
vases found at a high level might have been stored. Inside,
one or two partition walls divided the area off into two or
three rooms. In the longest hut, a narrow opening linked the
residential zone with the apse-shaped area used as a pantry,
while a second opening connected this to an open entrance
zone. In the other two huts, there was only one opening between
the main zone and the smaller pantry room. This is where a
number of vessels used to store food were found, while the
living area was the room containing the hearth and the circular
cooking plate, that had been reconstructed on several occasions.
The inhabitants had enough time to collect their most precious
belongings - bronze weapons in particular - with the exception
of a headdress made of plates cut out of the lower tusks of
young pigs, which was suspended from the wall of the smallest
hut. This must have been a typical style of head gear, manufactured
locally, as other plates, still unfinished or shattered, were
found in the other two huts and abandoned in the animal enclosures.
Today, archaeologists have a complete collections of the objects
in use in the huts. The two larger structures contained nearly
a hundred pottery vases, some of which are decorated with
parallel and mesh form incisions, others with triangles etched
out and filled with white paste, similar to those later found
in the Apennine culture. Some vessels containing the imprint
of their contents (almonds, flour, ears of barley and spelt)
were also found during the excavation.
With a view to exploring the earlier phases of the settlement,
the excavation was extended to the zones outside the three
structures. Close to hut 4, two foetuses, aged four and a
half and six months, were found buried among crushed pottery
remains.
The removal of the levels beneath the original surface covered
by the eruption brought to light traces of an older settlement,
in the form of a few flattened, perhaps burned, huts, laid
out in the same direction as the more recent structures, and
a number of metal processing furnaces.
First
results of the analysesThe first archaeological and botanical
analyses have brought to light carbonised macro-remains and
- one of the most important finds in Nola - marks in the ash
left by seeds of cereals, fruit and vegetables (ferns, oak
leaves, etc). Three types of cereal (monococcus, dicoccus
and barley) are present, generally in the form of ears. Imprints
of acorns and an almond (Amygdalus communis) have also been
identified, as well as part of an olive stone. The various
remains of carbonised wood from beeches, hop hornbeams and
fig trees, lead to the presumption of mixed plain woodlands
dominated by beech, not far from the settlement, at the margins
of cultivated area with fruit trees, pasture lands and cereal
crops. The analyses of the microfauna have brought to light
the consistent presence of Aricola terrestris, Microtus arvali
and Apodemus Cf sylvaticus. Amphibians were also found in
the wells (Anura) and in one case behind the straw covering
of one of the huts (bos bos). Land-living molluscs are widely
present throughout the area.
A
future archaeological park?
A project coordinated by the archaeological administration
body is attempting to keep the structures on-site, by setting
up an archaeological park. Due to the large quantity of data
obtained, it has been necessary to create a team of Italian
and foreign specialists, making use of important analysis
laboratories.
