Bur-Sagale eclipse

“In the eponymy of Bur-Sagale, revolt in the city of Assur. The sun was eclipsed.”
It serves as absolute anchor for Neo-Assyrian chronology.
Ancient cultures, including Assyria, viewed eclipses as omens of imminent destruction, and the empire was in chaos at this time, struggling with revolts, famines and two separate outbreaks of plague.
The Bur-Sagale eclipse occurred over the Assyrian capital city of Nineveh in the middle of the reign of Jeroboam II, who ruled Israel from 786 to 746 B.C. According to 2 Kings 14:25, the prophet Jonah lived and prophesied in Jeroboam's reign.
The eclipse took place around when Jonah arrived in Nineveh and urged the people to repent, otherwise the city would be destroyed.
