Nebra Sky Disk (NSD)
The Nebra Sky Disk (NSD) is a bronze disk about a foot in diameter and inlaid with gold astronomical symbols. “The disk, two bronze swords, two hatchets, a chisel, and fragments of spiral bracelets were discovered in 1999 by Henry Westphal and Mario Renner while they were treasure-hunting with a metal detector. Archaeological artefacts are the property of the state in Saxony-Anhalt. The hunters were operating without a license and knew their activity constituted looting and was illegal. They damaged the disk with their spade and destroyed parts of the site.” The original finders were eventually charged and received short prison sentences.(a)
Initially, the date of the disk was generally accepted as being around 1600 BC, but by the start of the 21st century, this was losing support and was being brought forward by as much as 1000 years.
Andis Kaulins has also written an extensive paper(i) on the Nebra Sky Disk. A 2014 update(j) on the Disk was posted by Claudia Bracholdt. 2020 brought further debate with the claim, in a lengthy paper, that the date of the Disk should be brought forward to the 1st millennium BC(c). This was followed by a shorter but vehement rebuttal(k)(l). In 2020, researchers at Goethe University have also advocated reducing the claimed age of the disk(a)(n).*
The Danish independent researcher, Ove Von Spaeth, has a wide-ranging article on cultural references to the Pleiades including the Nebra Sky Disk(d). He also touches on the subject of Atlantis.
A further possible consequence of the Theran eruption(s) was proposed after the discovery of the Nebra Sky Disk(g), which if was buried about 3,600 years ago. This is suggested to have resulted from the volcanic ash generated by the eruption blotting out the sun for up to 25 years. It is thought that the NSD had been used to synchronise the lunar and solar calendars(e) and when this was no longer possible the Disk was buried as some form of an offering. A contrary view is offered elsewhere on the Internet(f), as well as further controversy(h) led by Peter Schauer from the University of Regensburg.
A 2015 paper from Mel Copeland offers further background information as well as a review of some NSD theories(m).
