Based on these reference points, the ancient sea-going megalithic peoples then measured the earth by parallelograms, each in width equivalent to ca. This triangulation was carried on also to the East and West, as shown in the figure below . Southward, there are geodetic triangles with the Yucatan peninsula and from there on to Nazca . In Indo-European on the example of Latvian, to mera would mean that which measures . 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 diagonal north-south with the northeast and southeast sides formed what the Egyptians call a pyramid. The angle fromed 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. 36 degree sections. As Nazca shows us, these sections would not all be equal.
