1) Is there a difference between the Egyptian concept of the Ba and the Ka?
Are they both the spirits which travel around during the afterlife, or does
only one or the other do the traveling? Are they both the same? If different
2) How are ziggurats and step pyramids different? The ziggurat, developed in
Mesopotamia looks very similar outwardly. Are there difference in the
interior of the structure and/or its use?
3) Who first used the potters' wheel Sumerians or Chinese? and when was the
high-fired kiln developed and by whom?
I'd appreciate replies as soon as possible... Thanks 'Leni
