Columns, though associated with Greek and Roman architecture, were first constructed in Kemet, the land now known as Egypt. They have appeared in the enclosure of the step Pyramid of Djoser(built around 2700-2601 BCE) and other structures such as the now Ruins of the pyramid of Sahure and the Sun Temples of the Fifth Dynasty(2494-2345 BCE). The Fifth Dynasty lays between the Early Dynastic Period(3100-2686 BCE) and theOld Kingdom(2375-2345 BCE). It is evident in history that the columns are of African origin and not Greek, because the Archaic Greek period only dates as early as 800 BCE and the columns created by the Greeks appear in the Classical era(~500-323BCE). The infamous Greek columns are the Ionic, Doric and Corinthian styles. They appear some 2,000 years after the Fifth Dynasty of Kemet. There is currently no evidence or documentation of Greek architecture prior to the Classical Greek period aside from the wood and mud-brick homes that have long disintegrated back to the earth.
There are mainly two different types of columns the Kemites created. One being polygonal columns that later took on more shapes and sides. The second type of columns took on the resemblance of Plant organisms. It's probable that prestone architecture could have been supported by bundles of actual plant material and palm logs and could have been bound together with ropes, animal hide and mud. These types of columns were reserved for sacred structures.
