The Nebra Sky Disc, an ancient artifact inscribed on the UNESCO Memory of the World Register, offers insight into the cosmological beliefs of Early Bronze Age people. Discovered in Germany, the disc dates back to around 1600 BC and is believed to reflect advanced astronomical knowledge. A recent study used the latest methods to investigate the manufacturing process of the disc, concluding it was likely produced by forging a casted preform. Replicas were created to simulate the forging process, revealing the complexity of manufacturing such a thin disc in the Bronze Age. The study sheds light on the intricate craftsmanship of ancient civilizations.
