Chapter I The History of Non-Euclidean Geometry The Birth of Geometry We know that the study of geometry goes back at least four thousand years, as far back as the Babylonians (2000 to 1600 BC). However, Theodosius’ study was entirely based on the sphere as an object embedded in Euclidean space, and never considered it in the non-Euclidean sense.
