✓ What Is Physically Measured on Site
Dated samples, laser scans, stone weights, and dug finds kept separate from opinion.
- An illegal dig: The disc was reportedly dug up in 1999 by looters, as part of a hoard. Gebhard and Krause (2020) give this account. [2]
- Found with it: The Halle museum says the hoard held swords, axes, a chisel and arm spirals. It says the axes are a type typical of about 1600 BC. [3]
- Bark in the swords: The museum says birch bark in the sword handles was radiocarbon dated to the 16th to 15th centuries BC. [3]
- Not modern metal: The museum says the disc's bronze has no measurable radioactive lead. Newly made metal would still show it for about 100 years. [3]
- How it was made: A 2024 metal study says the disc was cast flat, then hammered while hot. It was heated and hammered about 10 times. [4]
- No direct date: Pernicka and colleagues (2020) say no method can yet date copper alloys exactly. So the date rests on the find spot and the objects found with it. [1]
🏛️ Mainstream Archaeological View
- Accepted timeline: Its keepers date the disc by the objects said to be found with it, to about 1600 BC. Two scholars argue it belongs to the first millennium BC.
- Stone & hardness: Not reported in the sources on this page. Mohs hardness: not reported in our sources.
- Quarry distance & alignment: Stone source not reported in the sources on this page. Orientation: Not reported in the sources on this page.
🧭 Leading Edge Proposal & Open Questions
- Contested: Gebhard and Krause (2020): Not a closed hoard? The authors say the dig results do not show the objects were buried together at that spot. Taken on its own, they say, the disc fits the first millennium BC best. [2]
- Contested: Pernicka and colleagues (2020): A reply: The authors say their critics leave out many later studies. They say soil traces, metal tests, police work and the looters' confession all link the disc to the hoard and the hill. [1]
- Open question: Which age? The disc is an artifact with a dating dispute. The disc cannot be dated on its own. The answer depends on whether it was truly found with the hoard. [1][2]
