Sky disc of Nebra decoded

The sky disc of Nebra has been decoded and gives new light to what those of the Bronze age knew about astronomy. The disc itself links both solar and lunar calendars to point to when the intercalary month was supposed to happen.

According to the ancient Babylonian rule, a thirteenth month should only be added to the lunar calendar only when one sees the constellation of the moon and the Pleiades exactly as they appear on the Nebra sky disc.

Another great knowledge that was lost, then found. Of course, we can already calculate the intercalary month, but it’s interesting that even back then, we could.
