I don't think I'm wrong when I say that the most beautiful objects of the "stone age" were made of skin, fabric, and especially wood. The "stone age" ought to be called the "wood age." How many African statues are made of stone, bone, or ivory? Maybe one in a thousand! And prehistoric man had no more ivory at his disposal than African tribes. Maybe even less. He must have had thousands of wooden fetishes, all gone now.
