Mesolithic disappointment
at Minehowe but bead find hints at more long-distance connections
A search for Mesolithic remains on a mound in
Tankerness has come up blank leaving the experts to continue their
quest for this "long lost" period of Orkney prehistory.
As part of this year's four-week archaeological
excavations around Minehowe,
an exploratory dig on Longhowe, the large mound by the road, was
looking for traces of the Mesolithic,
the period from 9000-4000BC and renowned in Orkney for the scarcity
of evidence.
The trenches followed the discovery of a number
of Mesolithic flints on Longhowe
last year, and geophysics work, which suggested that a "structure"
of some sort had once stood by the road-facing slope.
This led to great excitement at the time because
the people of the Mesolithic were nomadic hunter-gatherers, living
in small groups and shifting according the season and the availability
of food supplies.
The possibility of a permanent Mesolithic structure
in Orkney was a tantalising one.
But work on the mound over the past few weeks
has confirmed that the geophysics anomaly, once interpreted as a
possible structure, is actually due to the geological makeup of
Longhowe.
Orkney's long-lost Mesolithic will, for the time
being, remain hidden.
But despite the lack of permanent structures,
other evidence found this year does seem to indicate that Mesolithic
people once used the mound.
Co-directing the excavation with Orkney Archaeological
Trust's Nick Card, was Jane Downes, of Orkney College.
She explained: "We have evidence of stake-holes
and lots of scatterings of flint, which are either Mesolithic or
early Neolithic.
"So what we now think is that we do have
traces of a Mesolithic group, who stopped briefly on the top of
the mound, perhaps passing through on the way to or from hunting,
fishing or gathering grounds."
Back to the workshop
Moving back to Minehowe, this season's digs were
looking at various aspects of the Iron Age site, including the ditch
that encircled the monument and the metalworking structure by the
mound.
It is now becoming clear that this metalworking
building, which last year was found to have an
Iron Age woman buried under the floor, is much older than originally
thought.
The building's most recent hearth has been dated
to between 100BC to 100AD, placing the structure in the middle Iron
Age, and not the late Iron Age, as once thought.
This in turn makes the body found in the floor
even more intriguing.
Jane explained: "Formal burials in long cists
are generally found in the late Iron Age. The fact that this woman
was buried before this period makes her grave even more curious,
and much rarer."
The layout of the metalworking building is now
clearly visible along with its complex interior layout.
By the hearth, a triangular stone, found in the
middle of an area which seemed to have been devoted to copper work,
was probably where the craftsman sat while tending the items and
materials all around him.
A series of holes in the floor would appear to
be the remains of a complex series of furnishings around the fireplace.
These were perhaps supports, on which pots, crucibles or other metalworking
items, could be placed or hung over the fire.
Among the finds have been large bits of deer antler,
a segment of whalebone and a complete pin in the area around the
hearth. This pin, like a number found outside the building, had
broad, flattened ends which may imply that they were used as tools
perhaps for inscribing some of the items made on site.
A small piece of bone, carefully decorated with
a chevron design was also unearthed, and, at the time of writing,
another piece of suspected Roman glass had just come to light.
Somerset connection?
But the star find in 2005 hints at more long distance
connections between Iron Age Orkney and England.
An ornately decorated glass bead, found in a patch
of midden, has been studied carefully by Martin Carruthers, a PhD
student from Manchester University.
He said: "The bead appears to be an example
of a particular type of glass bead decorated with what is known
as a "Meare spiral".
"This distinctive style of yellow and black
bead takes its name from Meare in Somerset, in south-west England
an area that has yielded over 50 different types of glass bead."
The design, thought to date from 400-100BC, possibly
as late as 100AD, was made by painting vitreous glass onto the surface
of the glass beads. Although similar beads have been found across
Iron Age Britain, it is suspected that this is the first found as
far north as Orkney.
The bead, together with previous finds, once again
highlights the high status of the site, and in particular the power
and wealth of whoever was "responsible" for it. A fine
example of this is the massive ditch surrounding Minehowe. This
feature was recut, revetted and cleaned out on a number of occasions
tasks which would have required a considerable investment in time
and manpower.
Above this, it would require someone with the
authority and power to mobilise such a project. Whoever controlled
activities around Minehowe, seems to have had control over the people.
But although the fourth season has answered many
questions, as Jane Downes explained, many remain.
"We've managed to resolve a lot of things
around the site, but there were a lot of things to find answers
to," she said. "Numerous major questions remain. Where
is the settlement connected with Minehowe, for example? Where were
the people who were working, visiting and participating in activities
around the site?"
A question mark remains over the location of the
original chapel in the area. The traditional site of the nearby
St Ninian chapel was called into question by previous geophysics
scans. So it remains possible that the original early church site
goes against local tradition and was perhaps not where it is mapped.
But the work at Minehowe is significant in a national
sense in that it is allowing archaeologists to tie together various
elements of the Iron Age, and attach a coherent timescale.
"Radio-carbon dates from Minehowe and the
very diagnostic finds gathered, will provide an absolute chronology
for this, and many other sites and artefact types throughout Britain,"
said Jane.
