Babylonian Star Calendar Recreation (resin cast). About 4 by 3 inches. About 720 BC. A fragment of a circular star calendar from the library of Ashurbanipal in Nineveh. Among the library's huge cache of tablets, multiple fragments of late second millennium star charts and calendars were found. The two flat sides of the disc are inscribed in Assyrian Cuneiform with names of the months, names and figures of key stars and measurements of degrees. It is signed by the scribe Nab-Zuqup-Kenu, who lived during the reigns of Sargon II (720-704BC) and Sennacherib (703-680BC).
