Lodestone Compass: Chinese or Olmec Primacy?

  title={Lodestone Compass: Chinese or Olmec Primacy?},
  author={John B. Carlson},
  pages={753 - 760}
Considering the unique morphology (purposefully shaped polished bar with a groove) and composition (magnetic mineral with magnetic moment vector in the floating plane) of M-160, and acknowledging that the Olmec were a sophisticated people who possessed advanced knowledge and skill in working iron ore minerals, I would suggest for consideration that the Early Formative artifact M-160 was probably manufactured and used as what I have called a zeroth-order compass, if not a first-order compass… Expand
Pyramids and Ceremonial Centers in Mesoamerica and China: Were They Oriented Using a Magnetic Compass?
Fuson (1969), see also Carlson (1975), claims that Olmecs and Maya knew and used a (lodestone) compass for the orientation of pyramids, ceremonial and other important buildings, thousand years beforeExpand

Chinese tombs oriented by a compass: Evidence from paleomagnetic changes versus the age of tombs
Extant written records indicate that knowledge of an ancient type of compass in China is very old — dating back to before the Han dynasty (206 BC-220 AD) to at least the 4th century BC. GeomancyExpand
Abstract Archaeological excavations at sites of the Olmec civilization (1500 to 500 B.C. in present-day Mexico) have unearthed artifacts formed from massive iron oxide ores. Iron oxide ores wereExpand
Recent excavations in Belize have resulted in the discovery of an earlier period of sedentary occupation than has hitherto been documented in the Maya Lowlands. The Swasey phase is stratigraphicallyExpand
Chemical Characterization in Archaeology
Publisher Summary This chapter describes the requisites for a successful chemical characterization study of an archaeological problem. The first involves the subject matter. For the characterizationExpand
Knowledge of magnetism in pre-Columbian Mesoamerica
THAT the pre-Columbian peoples of Mesoamerica were familiar with the property of magnetism has been suggested by numerous researchers, among them Coe and Fuson1. Indeed, a flattened oblong piece ofExpand
Olmec archaeology: A half century of research and its accomplishments
The Olmec of Mexico's southern Gulf coast (3100-2450 B.P.) are the most famed of Formative period Mesoamerica's early complex cultures, and are particularly noted for their elaborate stone monuments.Expand
Settlement and Cultural Development at Chalcatzingo
Research conducted at a major Formative period archeological site in highland central Mexi- peninsula raises a number of questions about the actual nature of this cultural diffusion and the manner of its acceptance in other regions is still unclear. Expand
Knowledge of magnetism in ancient Mesoamerica: Precision measurements of the potbelly sculptures from Monte Alto, Guatemala
Archeological finds from Mesoamerica and elsewhere in the New World have yielded intriguing yet inconclusive evidence for an early appreciation of magnetism among Native American peoples. Here we useExpand


Astronomical Tables Intended for Use in Astro-Archaeological Studies
Tables are presented which give the rise-set azimuths of prominent celestial bodies and the heliacal rise-set dates of bright stars for a combination of epochs, latitudes, and horizon elevations.Expand
Olmec Civilization, Veracruz, Mexico: Dating of the San Lorenzo Phase
The excavations at San Lorenzo Tenochtitlan, Veracruz, show that the Olmec sculptures of this zone are associated with the San Lorenzo phase, which can be placed in the Early Formative period on the basis of ceramic comparisons. Expand
