While residing on the small Pacific island of Pohnpei in the 1990s, Carole Nervig discovered that a recent brush fire had exposed hundreds of previously unknown petroglyphs carved on gigantic boulders. This overgrown megalithic site, now called Pohnpaid, was unknown even to Pohnpei's state historic preservation officer. The petroglyphs were unlike others from Oceania, so Nervig began investigating and comparing them with petroglyphs and symbols from around the world. In this fully illustrated exploration, Nervig documents her discoveries on Pohnpei, revealing how the archetypal symbols of the Pohnpaid petroglyphs have exact counterparts in other ancient cultures and universal motifs throughout the world, including the Australian Aborigines, the Inca in Peru, the Vedic civilization of India, early Norse runes, and Japanese symbols. She provides evidence that Pohnpaid is closely related to--yet predates--neighbouring Nan Madol and shows how Pohnpaid was an outpost of the sunken Kahnihmuesio, a city of the now-vanished civilization of Mu, or Lemuria. Discussing the archaeo-astronomical function of the Pohnpaid stones, the author examines how many of the glyphs symbolize celestial phenomena and clearly reveal how their creators were sky watchers with a sophisticated understanding of astronomy, geophysics, geomancy, and engineering. She shows how the scientific concepts depicted in the petroglyphs reveal how the citizens of Mu had a much deeper understanding of the living Earth than we do, which gave them the ability to manipulate natural forces both physically and energetically. Combining archaeological evidence with traditional oral accounts, Nervig reveals Pohnpaid not only as a part of a geodetic network of ancient sacred sites and portals but also as a remnant of the now submerged but once enlightened Motherland of Mu.
