Kako so Egipčani gradili piramide??

The sloping terrain necessitated the creation of retaining walls on the north, south and west sides of the plaza. These walls are built of monoliths at their lowest level each weighing approximately 400 tons. The western, tallest retaining wall has a second course of monoliths containg the famous "trilithon"; a row of three stones each weighing in excess of 1000 tons. A fourth, still larger stone called "the stone of the south" (Hajar el Gouble) or "the stone of the pregnant woman" (Hajar el Hibla) lies unused in a nearby quarry. Had it been freed from the quarry, it would have been the largest stone ever moved, larger than the famous unfinished obelisk in Aswan. Another of the Roman ruins, the Great Court, has six 20 m-tall stone columns surviving, out of an original 128.

These stones represent the largest cut-stones from the ancient world. The unfinished stone is estimated to weigh 1500 tons.

Nekje sem tudi zasledil podatek, da kitajski zid (v resnici gre za več zidov) po volumnu prekaša vse egipčanske piramide. Kako je bil narejen, se ve. Tako kot se ve za piramide. Samo ta prave knjige je treba vzeti v roke :)

This 3000 years old obelisk in the Aswan quarry shows us an amazing feat of technology and archaeologists have learned much about the techniques of stone-cutting from examining this abandoned monument and from the tools which have been left behind (it developed a flaw during quarrying and was never completed, left to lie still attached to the living rock.)

If it had been extracted and erected as originally conceived, the Unfinished Obelisk would have stood 41.75 m (137 feet) tall and weighed 1,185 tons, dwarfing all others (the largest survivor, the Lateran obelisk in Rome, rises 105 feet and weighs "only" 455 tons.)

Dober les so že poznali - prav tako ni problem pripraviti podlago, da zdrži to težo.
