THE ZEP TEPI HYPOTHESIS - A Multidisciplinary Investigation into Saharan Cultural Memory and the Origins of Egyptian Sacred Symbolism

This paper presents the Saharan Corridor Hypothesis: the proposition that Saharan pastoral populations, displaced by the abrupt end of the African Humid Period (~5500 BCE), migrated northeast along a documented corridor from the western Sahara to the Nile Valley, carrying symbolic, linguistic, and ritual traditions that became foundational to Egyptian sacred iconography—including the Eye of Horus and the Zep Tepi cosmology. Drawing on published evidence from paleoclimatology, genetics, archaeology, rock art, material culture, and original pathogen screening of ancient DNA, the hypothesis traces a continuous chain from the Iberomaurusian populations of Morocco (15,000 BP) through the Fezzan corridor (Takarkori, 7,000 BP) to Nubia (A-Group, 3700 BCE) and finally to Old Kingdom Egypt (Nuwayrat genome, 2855–2570 BCE). The evidence includes: documented genetic continuity across the corridor; the eastward movement of domesticated crops, cattle cults, and textile technologies; synchronous dust isotope shifts in Nile sediments; and the authenticated presence of Mycobacterium tuberculosis and Brucella melitensis at corridor sites predating their Egyptian appearance. The hypothesis proposes that Egyptian sacred symbolism—the Eye of Horus (Wedjat) and the Zep Tepi cosmology—encodes geographic and astronomical memory of a specific western Saharan landscape: the Richat Structure (Mauritania), a concentric ring formation that held water during the Green Sahara and was occupied by humans for over two million years. The paper concludes with 13 testable predictions for future research, including ancient DNA analysis of A-Group Nubian skeletons, geochemical sourcing of Predynastic stone vessels, and systematic excavation of the Richat's annular depressions.
