nebra skydisc

On this day in 1999, near the eponymous village in the state of Sachsen-Anhalt two tomb-raiders discovered the Skydisc (Himmelsscheibe) of Nebra (previously), a four-thousand year old bronze artefact with inlaid gold symbols interpreted as the sun and lunar crescent and a cluster of stars that correspond to the Pleiades (the Seven Sisters) with an arch at the edge thought to represent the Chariot of the Sun, the band of the Milky Way or a rainbow.
Unlike anything else so far discovered dated to the era, it was originally thought to be a forgery but is now accepted as authentic. Unlicensed and prospecting with a metal detector, the amateur treasure hunters that found the prehistoric cache, which included swords, a hatchet and some jewellery besides, knew that their find would be considered looting and the hoard was traded on the black market through several collectors until the going rate exceeded a million Deustche Mark and the public became aware. The Nebra Skydisc is now on display in the Landesmuseum für Vorgeschichte (the State Museum of Prehistory) in Halle.
