The British Museum holds a collection of around 130,000 clay tablets from ancient Mesopotamia, with most remaining untranslated due to the complex languages they are written in. Recently deciphered tablets dating back to between 1900 and 1600 B.C. contain the earliest known mentions of omens related to lunar eclipses, a cause of great concern for the Babylonians who believed they were warnings of impending punishment from the gods. These translated tablets contain 61 ominous forecasts tied to different types of lunar eclipses, all signaling doom for the kingdom. In order to try to alter their fate, the Babylonian kings used various methods including celestial divination and extispicy to ward off potential disasters.
