"And on that day," says the Lord God, "I will make the Sun go down at noon, and darken the Earth in broad daylight." (Amos Chapter 8, Verse 9 - Old Testament)
The Assyrian eclipse is also known as Bur-Sagale (Bur-Saggile, Pur-Sagale or Par-Sagale) eclipse. It was recorded in Assyrian eponym lists, most likely in the 9th year of king Ashur-dan III. The actual short entry reads as follows:
Bur-Sagale of Guzana, revolt in the city of Assur. In the month Simanu an eclipse of the sun took place.
The phrase used - shamash ("the sun") akallu ("bent", "twisted", "crooked", "distorted", "obscured") - has been interpreted since the mid-19th century as a reference to a solar eclipse. In 1867, Henry Rawlinson decided that the most likely match was the nearly total eclipse of June 15, 763 BC, and this date has been widely accepted ever since.
A solar eclipse of June 15, 763 BCE mentioned in an Assyrian text is important for the Chronology of the Ancient Orient. Also known as the eclipse of Bur Sagale, it is the earliest solar eclipse mentioned in historical sources that has been identified successfully.
