The Four Corner Stones of a Land Survey in Ancient Egypt and Arabia: Sais (Sa al Hajar, Rosetta Stone), Nabta Playa (Table Rock Stone), Mecca (Kaaba), Dumat Al-Jandal (Missing Stone)

The image below shows that an ancient land survey of Ancient Egypt and Arabia was "anchored" in the Predynastic Era of Egypt (we estimate 3400 B.C.) by four massive corner stones that survive today as:

• The Rosetta Stone of Rashid (Rasheed), Egypt, which was used in a later era by Ptolemy, and in more recent times as a building stone. It has clearly been moved from its original location, which some have paced -- in our opinion correctly -- at Sais, today the city Sa al Hajar
  Sa al Hajar means "Sa of the Stone"
  30.96 N, 30.77 E [update corrects 30.86 to 30.96, also on image below]
  .
• Nabta Playa (massive Table Rock Stone), Egypt
  22.53 N, 30.70 E
  Nabta Playa has been falsely dated. The charcoal at the oasis right next to the megaliths dates to ca. the middle of the 4th millennium BC as does the charcoal of the Table Rock Stone. Older charcoal at the oasis is evidence of previous use of the oasis, but has nothing to do with the megaliths. Fred Wendorf and Romuald Schild write in Late Neolithic megalithic structures at Nabta Playa (Sahara), southwestern Egypt:
  

  "The test excavations recovered charcoal from a shelf on the edge of the pit under the structure, and this charcoal yielded a calibrated radiocarbon age between 5600 and 5400 years ago (4800 +- 80 years bp; DRI 3358).   This is the only date available for these structures, and it is about 1500 years later than we had estimated from the stratigraphic evidence.   This cluster differs from the other complex structures, and it may relate to a late phase in this phenomena; however, there is no other reason to reject the date."

The "stratigraphic evidence" has thus been improperly interpreted. 

• Mecca (Kaaba), the Black Stone, Saudi Arabia, damaged in antiquity
  21.42 N, 39.83 E
  .
• Dumat Al-Jandal, Saudi Arabia, ("the Missing Stone" of the four),
  Dumat Al-Jandal means "Dumah of the Stone"
  29.82 N, 39.87 E
  The nearby Rajajil megaliths have been dated to ca. 3000 BC. See Dharmendra, Saudi Arabia: Rajajil Stones Conjures Vision of England’s Stonehenge.

The longitudes and latitudes of these locations show that the ancients achieved substantial accuracy in their measurements. That these locations would form this kind of a measurement by chance is virtually impossible.

The Ancient Land Survey of Ancient Egypt and Arabia

As related by Peter Tompkins in Secrets of the Great Pyramid, Galahad Books, New York, 1971 and in that book's geodetic appendix by Livio Catulio Stecchini, there is no doubt that many ancient monuments of Earth were geodetically significant, especially in Egypt - which called itself To-Mera "the land of the mr triangulation", a line of interpretation first followed by the Egyptologist Karl H. Brugsch (Tompkins, p. 292).

Tompkins writes further ... p. 184:

"The Moslem shrine of Mecca is 10 degrees east of the western meridian of Egypt and 10 degrees south of Behdet. According to Stecchini the sacred black stone of the Kaaba was originally part of a set of four, placed in what he calls a pyramidical triangle from which the trigonometric functions of the shrine could be derived. Islamic tradition stresses the point that the Kaaba was originally a geodetic center. The essential element of the Kaaba consisted of four stones marking a square with diagonals running north-south and east-west. The diagonal north-south with the northeast and southeast
sides formed what the Egyptians call a pyramid. The angle formed by the diagonal with the southeast side was 36 degrees, from which Stecchini concludes that the trigonometric functions of the shrine were measured along the northeast side." The Rosetta Stone was originally surely one of these black geodetic stones [in the time of Ptolemy reused for the message which is placed upon it]." [emphasis added]

We predict that a massive large stone
will ultimately be found
in Dumat al Jandal or nearby to it
as the currently "missing" stone of the four.

Please note that our analysis here does not involve modern religious matters. Religion anciently involved geodetic land survey. Our interest concentrates on megalithic sites. This alleged survey is a major event of the megalithic era. See also megaliths.net at the geographic discussion of Africa.

We wrote about this topic previously in German. See:

What is vitally new in this posting is the recognition that the Rosetta Stone was originally at Sais, which completes the geodetic measurement picture.
