Dot Porter, Curator, Digital Research Services at the University of Pennsylvania Library, offers a video orientation to Penn Library’s LJS 99, a table of integer square roots. This partially baked clay tablet was created in Iraq, between 1999 and 1800 B.C., in Sumerian. It is a table of numbers whose square roots are integers, in Babylonian sexagesimal notation.
