The first to be built was Pyramid No B. It has

steps up the side, and it looks as if it was an

attempt to build something that we now call

a pyramid shape ． The steps

were a way of organizing the building and m

aking sure that it was safe ．

The steps look as if smaller and smallerboxes were placed one on top of the other to make the step design ． I think the second to be built was Pyramid No C ， which bends at the top ． It has smooth sides which the architects could have learned from building the steppyramid ． But the design is clearly not finished as the curve at the top of the pyramid is not smooth .

The Egyptian architects have not yet compl

etely mastered the art of building pyramids

with smoothly sloping sides ． I think the th

ird to be built was Pyramid No A ， which h

as smooth and evenly sloping sides ． It is

the shape that we call “a pyramid shape” to

day, so it must be the final one in this serie

s of buildings ．

From the pictures we can see that the three

pyramids all come to a point at the top ． It i

s reasonable to assume that the pharaoh ／god was close to the other gods ． The pha

raoh’s spirit could escape from the top of th

e pyramid and fly up to the sky ， where the

gods were thought to live ．
