i was thinking about the upside down/right side up question... if this
is truly how early man was first exposed to the 2 dimensional image,
they may have first traced the images onto tent walls or the cave walls
closest to the opening. then once they got the hang of drawing, they
could move deeper into the caves, applying what they had learned to
drawing without the camera. it would make sense that the drawings done
on the stones where the proportions are not realistic could have been
copied deep inside the lascaux cave. i think Gatton's idea is very
plausible! fun to think about the start of art!
