In this book, Richard Heath delves into the concealed cosmological knowledge of ancient matrilineal societies that thrived prior to the advent of mainstream arithmetic and Christianity. These societies were led by women who possessed advanced astronomical insight and sacred understanding, as evidenced in Malta, Gobekli Tepe in Turkey, and Crete. Heath unveils the intricate secrets hidden within their constructions, demonstrating how female astronomers of Malta constructed megaliths to analyze celestial bodies, encoded their discoveries within geometric temple designs, and developed an intricate astronomy tied to goddess worship. He examines the transition from sacred geometry to arithmetic in conjunction with the shift from matriarchal to patriarchal societies. Furthermore, Heath reveals how early Christians preserved this astronomical knowledge, encoding it in the rock-carved structures of Cappadocia, Turkey. The book concludes by discussing how Earth's unique harmonics and geometries within the cosmos were understood by these ancient astronomers, reflecting a divine and spiritual connection to the universe.
