The term pyramid comes from the Greek pyramids which literally means “the shape of the fire”. Some historians believe that the Greek term in turn comes from the Egyptian term per-em-us that in the Rhind Papyrus is used to represent the height of the pyramid (to the letter “what goes on”). In architecture, the pyramid has been used as an architectural typology with various functions, especially in ancient times, especially from Egyptians in Egypt, Sumerians in Mesopotamia, Maya and Aztecs in Central America.

Egyptian pyramids are square based, with the exception of some rectangular, with four smooth faces joining the edges, the Pyramidion at the top. After a growth phase of the monument’s monument, culminating in the unique Cheops Pyramid of the Seven Wonders of the Ancient World to be reached to us, the use of this monument continued for centuries, albeit with shorter forms, and also influenced culture neighboring; the last pyramids erected were those found in the realm of Meroe attributed to the 1st millennium BC.

The Mayan pyramids are also square-based but develop in a graded structure, generally with a temple-top structure.

Burials have also been found inside pyramids even if sporadically. In all latitudes there are tombs of various sizes, some abandoned, others adapted to varied functions; some still reach the original aim of taking drinking water from the ground. Most of these mounds are equipped with oblique tunnels excavated in the rock underneath, deep even tens of meters, ending with a chamber. In addition, most were built in regions threatened by periodic flooding. Where such galleries are still to be seen, it can be seen that these are made up of drywall walls, without mortar, to pass the water and moisture present in the ground and collect it in the tanks below. This process of construction in later stages is visible in many structures, such as Ziqqurat and Mastaba. For Egyptian pyramids, the transition from pyramid to pyramid-like pyramid point is attributable to a period when the construction was now unused as a hydraulic work. Indeed, the outer cover is of different material, and at present it is possible to identify, thanks to the atmospheric agents, the most robust internal structure under the crumpled mantle: see Cheops Pyramid, Sphinx, and the other Pyramids of Giza.
