Hi Tiompan

2) Waywardness of the circuit and Z8 -
Figure 12.1 shows that if the Sarsen stones arc chord of Y&Z holes had continued on the same radius (anti-clockwise) the fallen Sarsen would not have blocked the holes. If fact Z9 lies at the end of the fallen Sarsen, so there is no reason why the Y&Z holes should not have continued on the same radius to form a complete circle - as would be expected. The Eastern arc chord, if continued clockwise, would have extended beyond the midwinter sunrise point and even if there was no obstructing fallen Sarsen, would have coincided with an existing Sarsen stones ring, which would not be sensible.

Z12 appears to be partially covered by another fallen Sarsen, indicating that the Y&Z holes were built before the Sarsen stones started to fall into ruin.

Y8 is an oddity that appears to be an attempt to join the two displaced arcs chords ends together. I suspect a Z8 lies hidden under the fallen Sarsen, which would again indicate that the Y&Z holes were built before the Sarsen stones started to fall into ruin.

Dave ,

Yes , Z 12 is partially covered cover by stone 12 and stone 12 was depicted as fallen in Wood’s plan of 1740 , so we can say that stone 12 fell some time before that and Z12 was dug before it fell ,which gives us a lot of scope .

There is a dramatic change in the radius from Z7 to Z 9 ,if Z8 really was under the sarsen it would be quite a coincidence that it should be the pit that gets covered by a fallen sarsen just where the a major change takes place in the radius .But there is a much simpler explanation which also fits in with the rest of the evidence .

Y 6,7 and 8 and to a lesser extent Y 9 are all “off” ,Y7 is the closest to the monument and monument centre .
