ANCIENT AGRARIAN TO-DO LIST. Found by excavators in 1908, the famous Gezer Calendar is written on a 3.5-by-6-inch piece of limestone. It lists the months of the year associated with such agricultural activities as sowing and harvesting (see translation in the sidebar). Many scholars believed it was inscribed in Hebrew, but author Christopher Rollston hesitates in calling either the script or language Hebrew; the alternative is Phoenician.
