Science Frontiers ONLINE No. 52: Jul-Aug 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Costa rica's neglected stone spheres Books and articles on Stonehenge, the Easter Island statues, and the Egyptian pyramids are legion. Granted that these structures are important and intriguing, we still ask why Costa Rica's meticulously wrought stone spheres are languishing in the wings of science. They epitomize exquisite workmanship. Such geometric perfection rendered in granite is remarkable-- -for any ancient culture. Lastly, the stones' purpose completely escapes us. Why strew such masterpieces of stoneworking around and even buried under the dark jungle floors? M.T . Shoemaker also wonders about these things in a nice recapitulation of the stone-sphere mystery ... His compilation of facts and figures only impels us to learn more about the spheres and what their shapers had in mind. The spheres are found on the Diquis River delta, near the Pacific coast of southern Costa Rica. Stone-sphere sizes range from an inch to 8 feet in diameter. At least 186 spheres have been recorded in the literature. Surely many more were destroyed and other remain undiscovered. No local source exists for the granite; and no stone-working tools have been found near the spheres. "The best spheres are perhaps the finest examples of precision stonecarving in the ancient world." The maximum circumference error in a 6-foot, 7-inch diametre sphere in only 0.5 inch, or 0.2 %. The spheres are often grouped, ...

... Online All Issues This Issue Sourcebook Project Sourcebook Subjects Natural Stone Spheres Whenever we see nearly perfectly wrought stone spheres in natural settings, we usually jump to the conclusion that they have been shaped by human hands. We assume that natural forces are too erratic to sculpt such neat geometrical solids. This stance is sometimes justified, as confirmed by the hundreds of precisely executed stone spheres found in the jungles of Costa Rica. Nature herself, however, is often an expert craftswoman. Some concretions are beautifically spherical, so are some spheres fashioned in volcanic calderas. In Utah, though, southeast of Cleveland, in a formation called the Molen Reef, there are literally millions of stone spheres of more mysterious origin. E. Hansen described these in a recent issue of the Ancient American. "The spheres ... in size from as small as a baseball to over 10 feet in diameter. The bigger ones are more perfectly round than smaller examples. After a lifetime of trying to form a theory of how these were formed, I can only throw up my hands in surrender! They are clearly formed as mud on a lake bottom, because when two touch, one will indent the other, or both will be equally distorted. The mud simply hardened over time into sandstone." (Hansen, Evan; "Stone Spheres of the American West," Ancient American, no. 29, p. 31, 1999.) Comment. Smaller lithified "mudballs" (usually under 1-foot diameter) have been reported from many geological formations worldwide. (See ESA2-X3 in Neglected Geological ...

... as 12 miles out to sea. Pottery found near the figure has been carbondated at 200 BC and is assignable to the Paracas Culture. Separated by 130 miles from the Nazca Plain, with its famed giant figures, the Candelabra apparently is not the work of the Nazca people. It is puzzling why that such a figure would be placed where it could be seen best by sailors. As with Costa Rica's stone spheres, the Candelabra's makers, purpose, and symbology are in doubt. The Pisco geoglyph really doesn't match the motifs in our books on South American archeology. Some archeologists say it is only a trident, but who ever saw a trident like this? F. Joseph, the author of the present article, thinks it looks like a Jimson weed ... Furthermore, he states that there is a miniature version of the Candelabra drawn on a rock in California's Cleveland National Forest. Joseph associates the two candelabras in this way: The ancient inhabitants of Peru voyaged to California to collect Jimson weed and other hallucinatory drugs. When they sailed back to Peru with their cargo, they used the Pisco geoglyph as a navigational aid! (Joseph, Frank; "The Candelabra of the Andes," The Ancient American , 2:10, no. 10, 1995.)
