Babylonian astronomical diaries

The Babylonian astronomical diaries are a collection of Babylonian cuneiform texts that contain systematic records of astronomical observations and political events as well as predictions, based on astronomical observations. They also include other information such as commodity prices for particular dates and weather reports.[1][2]

Currently, they are stored in the British Museum.

It is suggested that the diaries were used as sources for the Babylonian Chronicles.

History

The Babylonians were the first to recognize that astronomical phenomena are periodic and to apply mathematics to their predictions. The oldest known significant astronomical text is Tablet 63 of the Enûma Anu Enlil collection, the Venus tablet of Ammisaduqa, which lists the first and the last visible risings of Venus over a period of about 21 years. It is the earliest evidence that planetary phenomena were recognised as periodic.

The systematic records of ominous phenomena in astronomical diaries began during the reign of Nabonassar (747–734 BC), when a significant increase in the quality and frequency of astronomical observations occurred. That allowed, for example, the discovery of a repeating 18-year Saros cycle of lunar eclipses.[3]
