Archaeologists recently uncovered a 4,600-year-old step pyramid near the Egyptian city of Edfu. It is the seventh of the "provincial" pyramids built decades before the Great Pyramid at Giza, LiveScience reports. The solid structures are built around Egypt and are nearly identical.
This newest step pyramid stands about 16 feet tall, but when it was new, it towered around 43 feet high. Like the other step pyramids, it was not used for royal burials and contains no inner chamber. And, actually, no one really know what these pyramids were used for.
It is notable that all were constructed close to important ancient capitals except for Seila (which was located close to the necropolis at Meidum). There also seem to be connections with important constellations (in particular Meskhetyu - the Big Adze) and special events in the Egyptian calendar; notably "Wepet Renpet" (the new year) and "Peret Sopdet" (the rising of Sirius before the inundation).
I'm going to throw this out there.
I have often wondered if these may have had a practical reason as well as astrological etc, the landscape around theses always seems very flat.
Is it possible the ancients were also geoforming for shade/agriculture reasons, I can't help but think these may have been intended to be "mountains".
Just an out there thought.
Other uses include:
It is the raw material for the manufacture of quicklime (calcium oxide), slaked lime (calcium hydroxide), cement and mortar.
Pulverized limestone is used as a soil conditioner to neutralize acidic soils.
It is crushed for use as aggregate—the solid base for many roads.
Geological formations of limestone are among the best petroleum reservoirs;
As a reagent in flue-gas desulfurization, it reacts with sulfur dioxide for air pollution control.
Glass making, in some circumstances, uses limestone.
It is added to toothpaste, paper, plastics, paint, tiles, and other materials as both white pigment and a cheap filler.
It can suppress methane explosions in underground coal mines.
Purified, it is added to bread and cereals as a source of calcium.
Calcium levels in livestock feed are supplemented with it, such as for poultry (when ground up).
It can be used for remineralizing and increasing the alkalinity of purified water to prevent pipe corrosion and to restore essential nutrient levels.
Used in blast furnaces, limestone binds with silica and other impurities to remove them from the iron.
It is often found in medicines and cosmetics.
It is used in sculptures because of its suitability for carving.
The fact that they are located along the Nile implies the Nile is the key to understanding their purpose. I suspect they acted as watchtowers for monitoring activity along the Nile. The Nile was the primary "highway" for commerce. And, if an invading army was going to attempt to overthrow the ruler, they would likely use the Nile to make a fast approach. The height of 40 ft.(approx.) would enable a good vantage point AND ensure the watchtower was not washed away when the Nile floods annually. When the water level is higher during flood seasons, the guards move the the next higher tier of the pyramid. The stepped pyramids allow for access to each higher level and a flat zone where guards can set up and monitor activity.
What strikes my imagination, is what else may have been at the peak of the pyramid. What there some kind of communications technology, or visual beacon that allowed a chain of communication along the Nile?
