I broke off the previous quote a bit too quickly .. here it continues

Two days later, the schoolboy son of one of the excavation helpers found another axe, on the outer face of stone 4. Through the summer, more axes were spotted, at least a dozen more on stone 4, on stone 3 and, again, on stone 53. In August, a visiting archaeologist, Brian Hope-Taylor, saw a second and smaller dagger on the side of 53, and other carvings were spotted that were too faint or weathered to identify easily. One, a worn sub-rectangular shape on stone 57, resembled early carvings in Brittany.
The flat axes were undoubtedly prehistoric, a standard Irish type with a broad cutting edge curved in a crescent and a tapering butt which was known in mainland Britain and dated to about 1600-1400 BC. They were further evidence of the northern aspect of the Wessex aristocracy's trade-routes.
The dagger was more exotic; its appearance -- with a straight-sided tapering blade expanding sideways into 'horns' at the base, short hilt and wide pommel -- could not be matched anywhere in northern Europe. But there were parallels from Greece, in the rich royal graves of the citadel of Mycenae itself, a dagger from shaft-grave VI and a dagger-carving on a stone over shaft-grave V.

Mr. Chippindale then forwards what I see as erroneous speculation,
(nothing I've ever been guilty of ;-), that a Mycenaean architect designed Stonehenge and was handsomely buried under Silbury Hill .... That aside, the apparent images of Irish axes and a Mycenaean dagger (s) imply a monument capital of considerable influence during this period .. as the plethora of barrow burials in the area attest
This would also help date the carvings to some time in the Middle Bronze Age, not likely before 1600 bce, the earlier part of the quoted range of these axes, (above); which is coincidentally when the Mycenaean age of Greek history is said to have begun ..
Wikipedia on Mycenae .. Turning again to Appendix 3 from
Hengeworld by Mike Pitts, (0-09-927875-8), page 341: the "large sarsen structures" of Stonehenge have been dated with 95% confidence to between 2461 & 2205 bce., at the inside more than 600 years earlier .. It also seems to place these carvings well after the bluestone circle & oval, said to date from between 2267 & 1983 bce. (page 342)
One final date clouds the issue somewhat: from Corlea, in County Longford, (Ireland), "timbers cut with metal blades" have been dated to 2259 plus or minus 9 years bce. .. This is within the 95% confidence range for the "large sarsen structures"
Of course, all this is in keeping with the axe hypothesis, not on the whole unreasonable .. The toadstool conjecture remains, however, dear to me
