Catacombs of Kom El Shoqafa The Catacombs of Kom El Shoqafa are located in Alexandria, Egypt. Half a kilometer to the northeast is the Serapeum of Alexandria, which is another archaeological site in the area. The Serapeum of Alexandria is considered to have been built by the Greeks in the 3rd century BC. Coordinates 31.178942, 29.893170 Description The site is thought to date to the Hellenistic period, and Roman, Greek, and Egyptian cultural attributes can be found throughout. The site is considered to have three levels dug into the rock, being up to 35 meters deep. The Catacombs consist of a triclinium, dining room, rotunda, Hall of Caracalla, and sarcophagi. The entrance is from the southeast side near the staircase at a 40° angle. The Catacombs' size is 25 metres by 50 metres. It is thought the site was an earlier burial ground where visitors brought clay pots of food for themselves, leaving the pots as they departed. Hence, this is where the name derived from. Analysis The tomb...
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.
