L38-2: The first calendar
Historians havelong been puzzled by dots, lines and symbols which have been engraved on walls,bones, and the ivory tusks of mammoths. The nomads who made these markingslived by hunting and fishing during the last Ice Age which began about 35,000B.C. and ended about 10,000 B.C. By correlating markings made in various partsof the world, historians have been able to read this difficult code. They havefound that it is connected with the passage of days and the phases of the moon.It is, in fact, a primitive type of calendar. It has long been known that thehunting scenes depicted on walls were not simply a form of artistic expression.They had a definite meaning, for they were as near as early man could get towriting. It is possible that there is a definite relation between thesepaintings and the markings that sometimes accompany them. It seems that man wasmaking a real effort to understand the seasons 20,000 years earlier than hasbeen supposed.
