Catacombs of Kom El Shoqafa

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...

Mitchell's Fold Stone Circle

Mitchell's Fold Stone Circle   Mitchell's Fold  (sometimes called Medgel's Fold or Madges Pinfold ) is a Bronze Age stone circle in southwest  Shropshire , located in the civil parish of  Chirbury with Brompton , at a height of 1083 ft (330m). Coordinates 52.578657,-3.028153 Stones There are 12 stones currently, of which 3 are tall and 9 are small with some part buried. Using the angles 4° and 18° clockwise and then the angle 26° the following are produced, the angles 4° and 18° produce the 26° and 12° angles. 4° clockwise 1,1,1,1,1,1,1,2,2,1 18° clockwise 2,1,1,1,2,2,1,2 4° 1×1×1×1×1׳√(221)=6.046 18° 2׳√(2212)=26.059 26° 2,1,1,1,1,1,2,1,2 After using the 26° aligning with the tallest stone, a 26° northeast angle gives the following, probably as an alignment check. 2,1,1,1,1,1,1,1,1,2 Taking each of the three angles and numbers produced aligns best as below, although there are '1's or '2's where there should be a ...

Coetan Arthur Dolmen

Coetan Arthur  Coetan Arthur, also known as Arthur's Quoit, is a dolmen  in Pembrokeshire, Wales. It is different from the Carreg Coetan Arthur monument near Newport and is the remains of a Neolithic burial chamber (also known as a quoit). Angles/coordinates  If the angle north equals 15° (1hr), then the stone's inclination angle of 25° could equal plus 10hrs or (25-15). 25° stone At 15° northeast Location 51.904° Altitude 42m Coordinates 51.904527,-5.307970 Meaning From other monuments, a dolmen with support stones represented the minimum and maximum tilt by its alignment angle and latitude. Assuming this to be correct then it gives a year of 3880 bc. A date can also be derived from the use of its altitude and coordinates, which are 42 and 51. (This is going straight to a date without the difference being 20° or 20° plus tilt). From these two angles and altitude and subtracting from 5510 gives a date of 1259 bc . 5510-4251=1...

Hurlers Stone Circles

Hurlers Stone Circles The Hurlers Stone Circles are a group of three stone circles in the civil parish of St Cleer, Cornwall, UK. The name "Hurlers" derives from a legend, in which men were playing Cornish hurling on a Sunday and were magically transformed into stones as punishment. The "Pipers" are supposed to be the figures of two men who played tunes on a Sunday and suffered the same fate. According to another legend, it is impossible to accurately count the number of standing stones. (The Pipers stones are not The Pipers St Buryan and are not included). Ralegh Radford excavated the site in the 1930s and partly restored the two northern circles by re-erecting some stones and placing marker stones in the positions of those missing. The use of the marker stones, if any in the 2nd circle, are not used, or do they adjust any of the measurements. Circles There are three circles at this location, along with the piper stones. The following ...

Castlelack Stone Row 

Castlelack Stone Row  Castlelack Stone Row or Castlenalacht Standing Stones are located by Castlenalact, Co. Cork, Ireland (or Castlelack). There are four stones in a row with a further stone 246m further north, the four in a row increase in size towards the east. Coordinates 51.798189,-8.745239 Stones The stones are aligned at 30° towards the northeast, and the stones stand at heights of 3.4m, 2.7m, 1.9m, and 1.9m. There are two further stones, one between the shorter stones but thought not to be original, and the other is 246m north as measured from one of the 1.9m stones and aligns north/south. The row is at an altitude of 143m, and the other stone further north is at 133m. Assuming the stones are 1m wide, then they are 2.5m apart. Measuring from this north/south alignment, then one short stone and the 2.7m stone are 2.5m away and give an angle of 0.582°, an area of 307m² and 494m perimeter. The other 3.4m tall stone is at an angle of 1.397°, an area of 738m² and perimeter of 49...

Ganghwa

Ganghwa Bugeunri Jiseokmyo  Ganghwa Bugeunri Jiseokmyo is a dolmen in Incheon, South Korea. Along with Ganghwa, there are the Gochang and Hwasun dolmens sites, which  were used as grave markers, and for ritual purposes during the first millennium BCE when the Megalithic Culture was prominent on the Korean Peninsula. Ganghwa has an additional capstone southwest at an angle of 67° towards the northeast, Ganghwa itself is at an angle of 37.75° towards the northeast which is it's latitudinal location. Coordinates 37.773610,126.437610 Similarity Lanyon Quoit a dolmen in Cornwall and Spinster's Rock represented the location at maximum and minimal tilt using its coordinates and angles. The difference in angle at Ganghwa is 29.25°, which is too large for tilt, which has ranged from 18.853°-20.05°. If 20° tilt is used, then a year of 3982 bc is produced, which is older than the 700-300 bc for the culture that lived there. A different way is that the altitu...

Boskednan Stone Circle

Boskednan Stone Circle  Boskednan Stone Circle is a partially restored prehistoric stone circle near Boskednan, Cornwall. The monument is traditionally known as the Nine Maidens or Nine Stones of Boskednan and not to be confused with the Nine Maidens in Devon. It is thought that the original structure may have contained as many as 22 upright stones. Description  The Boskednan Stone Circle is made up of eleven stones with a width of 23 metres (only the large stones are measured). One stone is angled towards the southeast, and one stone is a single stone. A measurement at the angled stone gives an angle of 15° and at right angles, the single stone is at 75°, which gives a centre point for the circle. Measurements  If the stones are measured from the centre, then the following angles are produced, the stones that produced the centre are in brackets. There are three different rows, (1) as all stone angles (2) as all differences in degrees (3) as stones in each ...

Lanyon Quoit

Lanyon Quoit Lanyon Quoit is a dolmen in Cornwall. It is thought to have collapsed in a storm in 1815 and re-erected nine years later. It could also be different from its original appearance. Lanyon Quoit, along with West   Lanyon Quoit and Bosiliack Barrow, are in the same location in Cornwall. A short distance further north are the Four Parish Rocks, Men an Tol, Boskednan Stone Circle (Nine Maidens), and Men Scryfa. Men Scryfa is a single Neolithic stone. Men an Tol is dated to about 2200-2500 bc and has a defined astronomical connection. Four Parish Rocks are a random selection of Neolithic stones. Bosiliack Barrow is a selection of Neolithic stones that are arranged so as to produce a circle and are similar to the Four Parish Rocks. Coordinates ( Lanyon Quoit) 50.147349,-5.599033 Comparing similar sites then Bosiliack Barrow and Four Parish Rocks are 1159m and 9° apart. Men an Tol and Men Scryfa are 342m and 4° apart. Lanyon Quoit and West Lanyon Q...

Castleruddery Stone Circle

  Castleruddery Stone Circle  Castleruddery Stone Circle is a recumbent stone circle and National Monument located in  County Wicklow , Ireland. It is 30 m (98 ft) in diameter (although east/west it is nearer 27m) with 29 stones, some of which are decorated with  cup marks .  The number of stones is nearer 37 stones on or near the circumference with 4 offset at the entrance and 6 in pairs inside. The cup marks could represent the latitude at the location.  The entrance is considered as the two enormous white quartz portal stones at the entrance, weighing about 15 tons. The circle itself is surrounded by an embankment about 1.2 m (3 ft 11 in) high and 4.5 m (15 ft) wide. Coordinates 52.991202,-6.636809 Meaning  After marking the tall stones horizontally and with 45° lines towards the northeast, a line can be drawn so as to pass through the intersections. These vertical intersecti...
