The site was first prepared by leveling the surface and then blocks of stone were transported and placed.
It was finished with an outer casing which was used to smooth the surface. Some interesting data: it is 756 feet long on each side, 480 feet high and is composed of approximately 2,300,000 blocks of stone, each averaging 2 1/2 tons in weight. This is a positional number system based on sixty, rather than ten.
The angles between two intersecting straight lines are equal. All knowledge and discoveries were attributed to Pythagoras.

E.) Parmenides was Greek philosopher who was a follower of Pythagoras. Philosophers of his time considered his philosophy to be quite negative.
Two triangles are congruent if they have two angles and one side equal. The rule that probably had the most impact on the history of mathematics was that all members of the brotherhood should observe strict loyalty to Pythagoras and the brotherhood and maintain secrecy. A remarkable aspect of the capture of Babylon is the fact that Cyrus allowed the Jews (who were exiled in Babylonia) to return home. He was an early believer of a cosmology that consisted of a spherical earth and a finite, motionless, spherical universe. Zeno wrote a book that reportedly contained forty paradoxes concerning the continuum.
When these "digits" were to multiply powers of 60, they were separated by more space.Wheeled vehicles first appeared in Mesopotamia (the region between the Tigris and the Euphrates Rivers ) around 3000 B. The wheels on the earliest vehicles were fixed to the axles rather than rotating around a hub.The axles themselves were held in place with wooden pegs on each side of the axle.Despite the limited surveying tools of the time, it is reported that no side is more than 8 inches different in length than another. The Sumerians represented the integers using cuneiform wedge patterns.Furthermore, the whole structure is perfectly oriented to the points of the compass. Their writing material consisted of a stylus and a tablet of soft clay which, when completed, was allowed to harden into a permanent document.
