A profound exploration of the simple numerical ratios that underlie our solar system, its musical harmony, and our earliest religious beliefs - Reveals how the orbits of Jupiter, Saturn, and Uranus relate to the Moon and the inner planets as an octave with musical scales - Explores how this harmonic planetary knowledge was encoded within ancient monuments and temples then spread within oral traditions - Explains how the solar system functions as a musical instrument and how this led to the rise of intelligent life, civilization, and culture on our planet As modern humans first walked the Earth roughly 70,000 years ago, the Moon's orbit came into harmonic resonance with the outer planets of Jupiter, Saturn, and Uranus. The common denominators underlying these harmonic relationships are the earliest prime numbers of the Fibonacci series--two, three, and five--the same numbers that interact to give us the harmonic relationships of music. Exploring the simple mathematical relationships that underlie the cycles of the solar system and the music of Earth, Richard Heath reveals how Neolithic astronomers discovered these ratios using megalithic monuments like Stonehenge and the Carnac stones, discoveries that informed later myths and stories including the Epic of Gilgamesh, the Resurrection of Osiris, the Rg Veda, the Hebrew Bible, Homer's epic tales, and the Return of Quetzalcoatl. He explains how this harmonic planetary knowledge formed the basis of the earliest religious systems, in which planets were seen as gods, and shows how they spread through Sumer, Egypt, and India into Babylon, Judea, Mexico, and archaic Greece. He exposes how the secret knowledge encoded within the Bible's god YHWH was lost as Greek logic and reason steadily weakened mythological beliefs. Revealing the mysteries of the octave and of our musical scales, Heath shows how the orbits of the outer and inner planets gave a structure to time, which our Moon's orbit could then turn into a harmonic matrix. He explains how planetary time came to function as a finely tuned musical instrument, leading to the rise of intelligent life on our planet. He demonstrates how this harmonic science of numbers can be read in the secret symbolism and sacred geometry of ancient cities such as Teotihuacan and in temples such as the Parthenon, connecting the higher worlds of planetary time and harmonics with the spiritual and physical life on Earth.
