Knowth Western Passage
The western passage extends for over a hundred feet (34 meters) and is known as the 'Undifferentiated Passage'
because it's hard to differentiate between the passage and the burial chamber itself. Remarkably, the basin stone from the western chamber
is currently lodged within the passage.
During a later phase in the tomb's history, an attempt was made
to extract the basin stone without realizing that its width exceeded that of the passage. Consequently,
the extraction process reached a point where the stone became firmly wedged, and it has remained in that position ever since.
The Western passage and chamber was re-discovered in 1967
The Western passage and chamber was re-discovered in 1967 by the archaeologist George
, he describes the event as follows.
In 1967, work on the western side revealed a souterrain (medieval storage chamber).
At one end, a wall seemed to run into the mound with a cavity beyond. On the following day,
July 11th, careful excavation enlarged the size of the cavity, and that enabled
a workman, with the aid of a torch, to look in. He reported that he could see a passage extending inwards
for a distance of some metres. On further excavation, using a flash lamp I could see much larger side stones
and capstones, one bearing megalithic art. We were thrilled, and all of us in the group - Quentin Dresser,
Tom Fanning, Sean Galvin, Fiona Stephens [later to become Mrs Eogan] and myself - speculated on the extent
of the tomb. The only way to solve that problem was to climb in, so we set off.
In some places the side orthostats were leaning inwards due to the immense weight of the overlying mound,
so we had to crouch and wriggle or go on hands and knees and in one place contend with a pool of muddy
water. As there were loose stones on the floor, this was a painful operation. However, in places we
could proceed in a hunched position. At one point there was a stone basin astride the passage with a
sill-stone beyond it. From there the passage was much better preserved and the capstone roof was much
higher. But there was no sign of an end to it.
As we flashed our lamp, we saw that practically every
orthostat was highly decorated, and immediately inside of the sill there appeared to be an anthropomorphic
figure with two staring eyes. We speculated that this ghostly figure might have represented a guardian of
the inner sanctum of the tomb. We could now walk upright, and soon reached the chamber, an undifferentiated
structure with two transverse sill-stones and a back stone decorated with parallel lines like a stone at the
entrance except for the absence of a vertical line.
By now we had lost all sense of time and distance, so Quentin Dresser volunteered to return to the outside
world to inform the rest of the team by now no doubt worried about our fate. Everyone then came into
the tomb, and with so much excitement we almost forgot to measure the passage length.
When we did, we found that it was 34 metres.
It was an incredible occasion, and one that remains as vividly in my memory today as it did
on the July evening. What a remarkable experience it was to have been
the first in a thousand years to enter one of the greatest monuments of Neolithic Europe.
Knowth West Orthostat 50 known as the Guardian stone or Sentry stone
The Megalithic Art of the Passage Tombs at Knowth, Co. Meath
Description of Knowth West Orthostat 50
The central portion of the main face is generally flat, and the sides and top slope back creating four planes,
all of which are carved and form a unified composition. Stage 1 consists of incised lines, some of which are deeply cut;
the principal panel is a series of chevrons at the lower-left, and there are some shorter, incised lines to the
right and on the top of the stone.
Stage 2 consists of an extensive composition of ribbon-like lines picked with a small to medium-sized, rounded point.
The composition centres on a vertical line enclosed in a tall, angular, clockwise spiral of two turns.
Outside this, a series of swirling lines extends upwards on the right and curves over to form a comma shape
around the spiral. Above this is a set of arcs opening downwards, and a circle enclosed in a single arc.
All are enclosed in a broad ribbon that follows the edge of the man face. On the sloping top of the stone
are a series of single and double arcs, all opening downwards. At the lower-left is a large circle.
Dispersed pickmarks occur in the centre of the pattern, and also on the upper-left side and on the top surface.
These were made with large points, some round and others chisel-like.
