The Sky Disc is one of the most important archaeological finds of the past century. It shows the world's oldest concrete depiction of astronomical phenomena that we know. Elements of the day and night sky mingle in front of an abstract network of stars. The sun and moon are not only depicted in their heavenly course, but also explained. A boat appears between the horizons on a nocturnal voyage across the celestial ocean. It is here for the first time recorded as a central mythical symbol in Europe. The Sky Disc gives us an insight into the knowledge of our ancestors about the course of the world and its religious interpretation 3, 600 years ago. The importance of the Nebra Sky Disc as the oldest concrete depiction of cosmic phenomena is also reflected in its inscription to the UNESCO document heritage register in June 2013.
