 SUMMARY: - The coin was made between 1605 and 1093 during the reign of King Olaf III. But how did a silver Norse coin, the only Norse artifact discovered at the site, travel all the way to Maine? - Flemming and other researchers assumed that these gold spirals were part of a priest-king’s costume or headwear, which would have been worn during ritual sun ceremonies. - The buckle-like object had been cast in a mold with a small leather ring attached to the bar, and it was about 2” by 1”. Thanks to its leather material, the researchers were able to estimate how old the object is through radiocarbon analysis: it’s 1,500 years old. - Rujim el-Hiri is another remnant of the Bronze Age, and it dates back to an estimated 3000 to 2700 BCE. The megalithic structure is located in Golan Heights and is made from approximately 44,000 tons of basalt stones. - Mohenjo-Daro can rival the greatness of ancient Rome, though it didn’t have a “central seat of government or evidence of a king or queen” according to a National Geographic article. - The Longyou Caves in Zhejiang province, China, aren’t your ordinary caves with cavernous passages, stalagmites, and stalactites. The 2,000-year-old man-made caves consist of 36 grottoes covering approximately 32,000 sq ft. - The Swimming Reindeer is made from the tip of a mammoth tusk that is 8” long. The sculptor possessed extraordinary creativity and skill: it was beautifully crafted with great detail using only stone tools.
