Orichalcum Found in 2,600 Year Old Shipwreck Off Coast of Sicily

I was recently reminded of a 2015 article from the Daily Mail reporting the discovery of 39 ingots of Orichalcum found in a 2,600 year old shipwreck off the coast of Sicily. You may wonder what is the significance of the find. It is because orichalcum, a red alloy composed primarily of copper and tin, was associated with Atlantis in Plato's account, which describes buildings being coated with the material.
