What if the greatest innovations of our time aren't new at all-but ancient secrets waiting to be remembered? Echoes of Genius: Unlocking the Lost Technologies of the Ancient World takes you on an extraordinary journey through time, exposing the hidden brilliance of civilisations long dismissed as primitive. With the curiosity of a scientist and the intuition of a seeker, Isadora Gronsveld uncovers how ancient cultures may have mastered principles we're only now beginning to understand-resonant frequencies, bioelectric healing, sacred geometry, sustainable engineering, and more. This isn't your typical history book. It's a bold, interdisciplinary exploration that blends archaeology, systems theory, myth, and modern science to challenge everything you think you know about progress. From the enigmatic stones of Gobekli Tepe to the coded symmetry of the Indus Valley, this book bridges the gap between forgotten genius and our future potential. Written in captivating prose and packed with thought-provoking insights, Echoes of Genius invites readers to engage with interactive prompts, re-examine "debunked" discoveries, and consider a radical question: have we truly advanced, or have we simply forgotten? If you're fascinated by ancient mysteries, emerging science, or the untold stories buried beneath mainstream history, this book is your missing link. Ideal for curious thinkers, spiritual explorers, history buffs, and anyone questioning the linear narrative of human evolution. Let this book rewire your perception. The past is not behind us-it's underneath us, echoing forward.
