At http://archaeologynewsnetwork.blogspot.co.uk/2016/04/a-3800-year-journey… … we have a clay tablet from Babylonia that was originally pulled from an excavation of Old Babylonian (Middle Bronze Age) archaeology in what is now Iraq. It concerns school work – and the knowledge of mathematics in the second millennium BC.
The tablet is know as YBC 7289 (OLd Babylonian Mathematical Text) and was donated to Yale in 1909. Its importance has been known since at least 1945 when Neugabauer and Sachs published an article on its translated text (cuneiform to modern). As is now well known the tablet shows Babylonians understood the principles of the 'Pythagorem Theorem' – long before Pythagoras (who lived in the first millennium BC)This is all well known and well documented and has been publicised all over again by Yale University as part of their digitisation programme.
