Nebra sky disc, Nebra

The Nebra sky disc is a bronze disc of around 30 cm diameter and a weight of 2.2 kg, having a blue-green patina and inlaid with gold symbols. These symbols are interpreted generally as the Sun or full moon, a lunar crescent, and stars. Two golden arcs along the sides, interpreted to mark the angle between the solstices, were added later. A final addition was another arc at the bottom with internal parallel lines. ()
