The Nebra Sky Disk is one of the most fascinating, and some would say controversial, archaeological finds of recent years. Dated to 1600 BCE, this bronze disk has a diameter of 32cm (about the size of a vinyl LP) and weighs around 2 kg. It is patinated blue-green and embossed with gold leaf symbols which appear to represent a crescent moon, the sun (or perhaps a full moon), stars, a curved gold band, interpreted as a sun boat, and a further gold band on the edge of the disk which probably represent one of the horizons (another gold band on the opposite side is missing).
