This book contains the first published results of Schwaller's 12 years of research at the temple of Luxor and its implications for interpreting the symbolic and mathematical processes of the Egyptians through their sacred architecture. R. A. Schwaller de Lubicz (1887-1961) was one of the most important philosophers, mathematicians, and Egyptologists of this century. His elucidation of the temple at Luxor and his presentation of the Egyptian understanding of a special quality of innate consciousness form a bridge that links the sacred science of the Ancients to its rediscovery in our own time.
