Context

  • The British Museum in London will display an ancient object called the Nebra Sky Disc, which is thought to be the world’s oldest concrete depiction of stars.

 

About

  • About 3,600 years ago, the disc was ritually buried along with two swords, axes, two spiral arm-rings and one bronze chisel near Nebra in Germany. The burial of these objects is thought to be made as a dedication to gods.
  • While the exact purpose of the disc cannot be determined, hypotheses about its existence have imagined it as an astronomical clock, a work of art and a religious symbol.
  • The bronze disc, which depicts the world’s oldest representation of “specific astronomical phenomenon” had five phases over its history.
  • In the first phase, the disc illustrated the night sky with 32 gold stars, including the Pleiades, a hold orb representing the sun or a full moon and a crescent moon.
  • This illustration served as a reminder of when it was necessary to synchronise the lunar and solar years by inserting a leap month.
  • The knowledge required to create the object was “entirely local” and was drawn from observing the heavens from atop the Mittelberg mountain.

Note: The Mittelberg is an 803.6 m high mountain located in the Thuringian Highland, Germany.
