What if the Great Sphinx had never been alone? Starting from the premise that the Giza Plateau represents a sophisticated and monumental unified project, author Damiano Piras develops a coherent and methodical line of reasoning to investigate the possible existence and location of a twin Sphinx. Through a detailed analysis of a specific area, a remarkable convergence of geometric, archaeoastronomical, historical, and religious indicators emerges. The investigation culminates in a twofold verification process: first through on-site observations during the striking equinoctial alignments, and subsequently through mathematical calculations conducted with specialized software. The results reveal a breathtaking celestial symmetry that manifests not only during the equinoxes, but also during the two opposing solstices, completing the majestic symbolic and spatial design of Giza. The Dawn of a New Sphinx presents a well-documented and compelling thesis, constructing step by step a persuasive case for the possible existence of a long-concealed secret, preserved for millennia beneath the sands of the desert.
