The Principles and Objects of Geology, with Special Reference to the Geology of Egypt

This 1911 work represents one of the first systematic scientific examinations of Egypt's geological makeup, written when geology as a discipline was revolutionizing our understanding of deep time and planetary processes. Hume documents the limestone plateaus, granite massifs, sandstone formations, and alluvial deposits that comprise the Egyptian landscape, tracing how the ancient Nile's continuous sedimentation created the fertile valley that would become the cradle of one of history's greatest civilizations. The book explains fundamental geological processes, erosion, faulting, sedimentation, metamorphosis, while grounding each principle in specific Egyptian formations visible across the desert, the Sinai, and the Red Sea hills. What elevates this work beyond a mere technical manual is Hume's insistence that geology and human history are inseparable: the pyramids rise from particular limestone quarries, ancient Egyptian monuments were carved from specific granite sources, and the Empire's wealth in gold and building stone can only be understood through geological science. This text remains essential reading for anyone seeking to understand how Egypt's physical foundations shaped its extraordinary cultural achievements.
