The high precision Lenses of the Vikings.
Today’s aspherically ground glasses for high precision optical instruments are generally held to be an achievement of our highly technological world, a product of the computer age. A mistaken view. Actually, the first such instruments date back to the 12th century. After several years of painstaking analyses, eyeglass experts have now confirmed that the ground rock crystal objects from the 12th century found in Swedish Viking graves were made almost to perfection.
If the lens is placed on a text page, the effect is the same as that obtained with a modern magnification glass measuring 5cm in diameter. It was not until the 17th century that mathematician René Descartes successfully made theoretical calculations about aspherical lenses. However, this precision technology was not known to have been used in practice before the 20th century. So how did they develop such sophisticated optical devices 8 centuries ago? Researchers from the University of California at Berkeley now want to further investigate the sensational “Viking” lenses. It is generally believed that the unusual items were originally manufactured in Byzantium, where they were purchased or stolen by the Vikings.
Place of discovery: Viking graves on the Baltic Sea island of Gotland, Sweden
Age: 12th century or earlier
Welcome to our strange and weird world of unsolved ancient mysteries. Here you will find many unusual artifacts and evidence of lost and mostly forgotten people of our ancient past. From clay pot batteries to crystal skulls to giant bones, here you will find information on these and many more discoveries that defy explanation to many archeaologists and historians. A few are generally accepted as fakes or the official explanation will not go with new information that have been found by alternative and weekend researchers. The decision is yours to either accept these artifacts as real evidence of lost technologies and knowledge or you can accept the official explanations given by the professionals in archeaology and history. The choice is yours. These postings and images are an attempt to preserve what information have been learned about our ancient past and I hope these postings will add to a current researcher’s project. Please share this page will all your friends and family and to anyone who would be interested in learning about our unusual and strange ancient past. Thank you.
