Down Tor Stone Circle Down Tor Stone Circle is a stone circle near Down Tor, Dartmoor. Also called Hingston Hill Cairn. Foggintor Quarry is not far to the northwest, where the stones could have been quarried, along with Down Tor, which is currently a national park. Crazywell Cross is to the north and Drizzlecombe to the south. Coordinates 50.506060,-3.994103 Description Down Tor Stone Circle consists of a long stone row with a circle of stones at the end towards the southwest. This can be considered similar to Drizzlecombe in shape and construction, and is 2 kilometers away. Measurements This tor and circle are angled at 22° towards the southwest, with the row at a length of 755 feet or 230 metres. Analysis It is possible that Down Tor Stone Circle is similar to Drizzlecombe, which was shown to be possibly connected with the golden ratio and π or 9πφ together. The circle is 40 meters wide. If using the 22° on the circle towards the northwest, then all stones pair...
Dolmen di Sa Coveccada and Perdas Fittas
Both of these stone monuments are on Sardinian and were constructed in the neolithic to bronze age.
Dolmen di Sa Coveccada is a monument thought to be a tomb where the dead would be laid to rest after a ritual and was thought to be connected with Ozieri culture from the Neolithic 3500-2900 bc until being dated more recent.
The monument is aligned at 31° towards the south, in about 2700 bc this would be aligned at 23.75°, coincidentally it is also aligned at 8.5° to Gravinis and to maximum tilt which might have been a construction consideration.
Construction
As with most neolithic builds stones are stood up vertically then a cap stone is positioned with the soil being dug away, some of these stone monuments of this shape are considered to be communication devices using methane/air mixtures which were more in use in Neolithic times. The fact that this was dated as newer means that it was probably an early bronze age construction copy not having the same use.
Perdas Fittas in Sardinian
Referred to as monoliths-menhirs (Perdas Fittas in Sardinian) and crafted in a variety of styles and carved patterns onto the surfaces.
The ones in question are at the Civic Archaeological Museum of the Menhir in the village of Laconi, in the Sarcidano region of Sardinia.
A common theme runs through these, that of a gnomon, not the neolithic Mên-an-Tol in Cornwall but a mobile variation of the same thing. The shapes are that of an arrow and part circle and are depicted in a variety of ways.
Gnomon
These would have been made from wood and twine and acted vary similiar to a gun's sight, the adjustable middle sight could be moved forward and backward for the purpose of aligning with the front sight and an object in question. This then could be used to take angles and distances using triangle equations, a form of triangulation.
It probably was made from two wooden pieces where one would be used to mark east/west while the second would align with the object, a height could also be measured, thus giving two angles.
The circular wooden disc would achieve this and might have rotated, giving some fine tuning. Most likely, it would have been crafted at about 2/3 foot long.
Connecting these to the same time is not just that they are on the same island but the use of and depiction of the gnomon with the alignment of the tomb at 8.5° off Gravinis and 8.5° towards max tilt.
