[00:01.040]--- lesson 38 The first calendar [00:05.880]--- Listen to the tape then answer the question below. [00:11.800]--- What is the importance of the dots, lines, and symbols engraved on stone, bones and ivory? [00:21.680]Future historians will be in a unique position when they come to record the history of our own times. [00:29.200]They will hardly know which facts to select from the great mass of evidence that steadily accumulates. [00:36.840]What is more, they will not have to rely solely on the written word. [00:41.880]Films, videos, CDs and CD-ROMS are just some of the bewildering amount of information they will have. [00:50.680]They will be able, as it were, to see and hear us in action. [00:55.280]But the historian attempting to reconstruct the distant past is always faced with a difficult task. [01:02.800]He has to deduce what he can from the few scanty clues available. [01:08.120]Even seemingly insignificant remains can shed interesting light on the history of early man. [01:15.040]Up to now, historians have assumed that calendars came into being with the advent of agriculture, [01:22.000]for then man was faced with a real need to understand something about the seasons. [01:27.640]Recent scientific evidence seems to indicate that this assumption is incorrect. [01:34.040]Historians have long been puzzled by dots, lines and symbols which have been engraved on walls, bones, and the ivory tusks of mammoths. [01:45.280]The nomads who made these markings lived by hunting and fishing during the last Ice Age which began about 35,000 B.C. and ended about 10,000 B.C. [01:58.480]By correlating markings made in various parts of the world, historians have been able to read this difficult code. [02:06.800]They have found that it is connected with the passage of days and the phases of the moon. [02:12.880]It is, in fact, a primitive type of calendar. [02:17.040]It has long been known that the hunting scenes depicted on walls were not simply a form of artistic expression. [02:24.880]They had a definite meaning, for they were as near as early man could get to writing. [02:31.040]It is possible that there is a definite relation between these paintings and the markings that sometimes accompany them. [02:39.040]It seems that man was making a real effort to understand the seasons 20,000 years earlier than has been supposed.
