orichalcum

A team of marine archaeologists have discovered several dozen ingots scattered across the sandy sea floor near a 2,600-year-old shipwreck off the coast of Sicily. The ingots were made from orichalcum, a rare cast metal which ancient Greek philosopher Plato wrote was from the legendary city of Atlantis. According to Inquisitr, a total of 39 ingots (metal cast into rectangular blocks) were found close to a shipwreck in 2015. In 2017, Seeker reported another cache of the same metal was found. There were 47 more ingots discovered, for a total of 86 metal pieces found to date. The shipwreck itself was found in 1988 lying in shallow waters about 300 meters (1,000ft) off the coast of Gela in Sicily. Gela
