'Sunstone' crystals may have helped seafarers to find the Sun on cloudy days. A Viking legend tells of a glowing 'sunstone' that, when held up to the sky, revealed the position of the Sun even on a cloudy day. It sounds like magic, but scientists measuring the properties of light in the sky say that polarizing crystals — which function in the same way as the mythical sunstone — could have helped ancient sailors to cross the northern Atlantic. A review of their evidence is published today in Philosophical Transactions of the Royal Society B1. The Vikings, seafarers from Scandinavia...

How Vikings Might Have Navigated on Cloudy Days By Corey Binns Special to LiveScience posted: 02 March 2007 08:33 am ET Vikings navigated the oceans with sundials aboard their Norse ships. But on an overcast day, sundials would have been useless. Many researchers have suggested that the on foggy days, Vikings looked toward the sky through rock crystals called sunstones to give them direction. No one had tested the theory until recently. A team sailed the Arctic Ocean aboard the Swedish icebreaker Oden and found that sunstones could indeed light the way in foggy and cloudy conditions. Would have...

The sun was not necessary for Vikings to navigate, say researchers Vikings may have used a special crystal called a sunstone to help navigate the seas even when the sun was obscured by fog or cloud, a study has suggested. Researchers from Hungary ran a test with sunstones in the Arctic ocean, and found that the crystals can reveal the sun's position even in bad weather. This would have allowed the Vikings to navigate successfully, they say. The sunstone theory has been around for 40 years, but some academics have treated it with extreme scepticism. Researcher Gabor Horvath from...

Vikings used rocks from Iceland to navigate the high seas, suggests a new study. In Norse legends, sunstones are said to have guided seafarers to North America. Now an international team of scientists report in the journal the Proceedings of the Royal Society A that the Icelandic spars behave like mythical sunstones and polarise light. By holding the stones aloft, voyaging Vikings could have used them to find the sun in the sky. The Vikings were skilled navigators and travelled thousand of kilometres between Northern Europe and North America. But without a magnetic compass, which was not invented until the...

By using aerial photographs and geophysical surveys, Warsaw archaeologists not only confirmed the location of settlement dating back more than two thousand years in Respublikaniec (Kherson Oblast), but also discovered previously unknown structures in its area... Archaeologists determined that the settlement was probably founded in the 2nd century BC. Researchers also discovered the exact outline of its fortifications -- defensive walls and ditches. In addition to defensive functions, the place also served as a venue of trade between residents of the Dnieper steppes and the ancient world, represented by the nearby Greek colony -- Olbia. The settlement could also have...

France’s biggest trove of Gaulish coins has been unearthed in Brittany. Archeologists found them while searching along the route of a bypass under construction in the Côtes d’Armor. The coins are in the hands of specialist restorers and will go on display in the département. The trove consists of 545 gold-silver-copper coins: 58 staters and 487 quarterstaters. ‘Stater’ is the generic term for antique coins. They lay a foot beneath the earth’s surface near Laniscat, 64km south of Saint-Brieuc, at a known Iron Age manor house or farm site, and date to 75- 50BC. They are very well preserved. Inrap,...

The Shipping of Michigan Copper across the Atlantic in the Bronze Age (Isle Royale and Keweenaw Peninsula, c. 2400BC-1200 BC) Summary Recent scientific literature has come to the conclusion that the major source of the copper that swept through the European Bronze Age after 2500 BC is unknown. However, these studies claim that the 10 tons of copper oxhide ingots recovered from the late Bronze Age (1300 BC) Uluburun shipwreck off the coast of Turkey was “extraordinarily pure” (more than 99.5% pure), and that it was not the product of smelting from ore. The oxhides are all brittle “blister copper”,...

The remains of an ancient Greek cargo ship that sank more than 2,300 years ago have been uncovered with a deep-sea robot, archaeologists announced today. The ship was carrying hundreds of ceramic jars of wine and olive oil and went down off Chios and the Oinoussai islands in the eastern Aegean Sea sometime around 350 B.C. Archeologists speculate that a fire or rough weather may have sunk the ship. The wreckage was found submerged beneath 200 feet (60 meters) of water. The researchers hope that the shipwreck will provide clues about the trade network that existed between the ancient Greek...

The discovery of a 2,300-year-old shipwreck between the classical trading centers of Rhodes and Alexandria adds to the corpus of evidence that is challenging the long-held assumption that ancient sailors lacked the navigational skills to sail large distances across open water, and were instead restricted to following the coastline during their voyages. Four other possibly ancient wrecks lie nearby... Despite its depth, the site is typical for an ancient shipwreck. The vessel came to rest on the bottom and eventually listed over onto its side. In this case, the ship heeled over to port. As its wooden hull lost...

Archaeologists in Cyprus have discovered what they believe could be the oldest evidence yet that organized groups of ancient mariners were plying the east Mediterranean, possibly as far back as 14,000 years ago... about 30 miles away from the closest land mass, may have been gradually populated about that time, and up to 2,000 years earlier than previously thought... The discovery at a coastal site on the island's northwest has revealed chipped tools submerged in the sea and made with local stone which could be the earliest trace yet of human activity in Cyprus. U.S. and Cypriot archaeologists conducting the...

A team of marine archeologists using sonar scanners has discovered new underwater treasures in the Italian seas. Trading vessels dating from the first century BC to the 5th through 7th centuries AD were found in the waters of the Pontine Islands. Their cargoes were found to be intact. Italian culture authorities and the Aurora Trust, a U.S. foundation which promotes underwater exploration in the Mediterranean, discovered four shipwrecks resting on the seabed. The discovery was made in a beautiful stretch of sea off the tiny rock of Zannone, part of the Pontine Islands in central Italy. After the discovery, the...

FULL TITLE: Controversial footprint discovery suggests human-like creatures may have roamed Crete nearly 6m years ago The human foot is distinctive. Our five toes lack claws, we normally present the sole of our foot flat to the ground, and our first and second toes are longer than the smaller ones. In comparison to our fellow primates, our big toes are in line with the long axis of the foot – they don't stick out to one side. In fact, some would argue that one of the defining characteristics of being part of the human clade is the shape of our...

For a long time, scientists had assumed a gradual expansion of African people through Sinai into both Europe and Asia. Then, bizarrely, it became clear from both genetics and archaeology that Europe was peopled later (after 40,000 years ago) than Australia (before 50,000 years ago). Meanwhile, the geneticists were beginning to insist that many Africans and all non-Africans shared closely related DNA sequences that originated only after about 70,000-60,000 years ago in Africa. So a new idea was born, sometimes called the "beachcomber express," in which the first ex-Africans were seashore dwellers who spread rapidly around the coast of the...

Four previously unknown shipwrecks have been discovered some 30 kilometers off the Bay of Irakleio, Crete, in recent underwater exploration conducted by the ephorate of underwater antiquities. The new finds comprise two Roman era shipwrecks, one containing 1st and 2nd-century Cretan amphorae and the other containing 5th-7th century post-Roman era amphorae, and two shipwrecks containing Byzantine amphorae, dated from the 8th-9th century and later. The finds, which were made south and east of the Dia islet, which lies 7 nautical miles north of Irakleio, were documented and taken ashore for further analysis. Three more recent shipwrecks were also discovered, as...

Iceland was once home to a unique subspecies of walrus, but the animals had vanished by the mid-14th century, just 500 years after the arrival of Norse settlers... Researchers have known for years that walruses once lived on Iceland, but opinion has been divided on whether they vanished before or after humans arrived. To settle the debate, Morten Tange Olsen and Xénia Keighley at the University of Copenhagen in Denmark carbon dated the remains of 34 walruses found in western Iceland. Three of the walruses died after the year 874 – the date permanent settlers are thought to have reached...

When the Bronze Age hit ancient Israel, the copper-rich region was able to quickly source seven of the eight ingredients needed to produce the alloy at Timna and other mines. But where tin -- another one-eighth of the metal's recipe -- came from has been a lingering mystery for scholars. A new paper from an international team of researchers proposes a surprisingly faraway source -- Cornwall. In a paper published in June on the open-access, peer-reviewed scientific journal PLOS One, the authors analyze 27 tin ingots, or blocks, from five sites bordering the eastern Mediterranean Sea. For decades, researchers have...

The Maritime Archaeological Trust has discovered a new 8,000 year old structure next to what is believed to be the oldest boat building site in the world on the Isle of Wight. Director of the Maritime Archaeological Trust, Garry Momber, said "This new discovery is particularly important as the wooden platform is part of a site that doubles the amount of worked wood found in the UK from a period that lasted 5,500 years." The site lies east of Yarmouth, and the new platform is the most intact, wooden Middle Stone Age structure ever found in the UK. The site...

Some people have claimed that Greenland was no warmer 1,000 years ago than it is today...In this essay, I will examine some of the historical facts concerning Greenland starting 1,000 years ago and will then attempt to demonstrate how much warmer Greenland had to be in order to accommodate the history that transpired in this region.

“There are but 155 years left … at which time … the world will come to an end,” wrote Christopher Columbus in his book “Libro de Las Profecias,” composed in 1502 between his third and fourth voyages. Columbus continued: “… The sign which convinces me that our Lord is hastening the end of the world is the preaching of the Gospel recently in so many lands.” Though his predictions were off, Columbus’ writings revealed his motivation for setting sail on his first voyage Aug. 3, 1492, with the Nina, Pinta and the Santa Maria. He sought to find a sea...

Since Colchis was famous in antiquity for gold and precious metal -- it's where the Greek hero Jason went to grab the legendary Golden Fleece -- you'd be wearing gold-spangled robes while pouring and drinking your famous Colchian wine from gold or silver vessels. You'd also be so rich you could afford to bury your wine service with you... A fascinating exhibition, "Wine, Worship & Sacrifice: The Golden Graves of Ancient Vani" at the Smithsonian's Sackler Gallery in Washington, D.C., through Feb. 24, gives a thrilling image of the plenty that nobility enjoyed in that far corner of the ancient...
