"In the administration of Egypt,
the area between 29° 51' and 30° 06' North
was organized as a special district
which did not belong
either to the list of nomes (provinces) of Southern Egypt
nor to that of nomes of Northern Egypt."

The hieroglyph for this district is a rectangle
which is either empty or filled with water or fish.

A distinguished Egyptologist, being at a loss for a better explanation,
has read this hieroglyph as 'fishpond'.
He did not realize that a rectangle, either empty or filled with water or fish,
is the symbol of the Great Square of Pegasus.

In Hamlet's Mill, de Santillana and Dechend have presented
illustrations of this symbolism occurring all over the globe....
There are in the sky four stars which are at a distance
of about 15° from each other
and mark a square with sides that run
according to the celestial meridians or parallels;
these four stars form the Square of Pegasus....

The Square of Pegasus was considered as
the starting point in the mapping of the sky.

The ancients, from the Sumerians to the Romans,
in surveying land began by marking a square of standard dimension
and then proceeded to measure out of it in a checkerboard pattern.

In cuneiform texts the name iku is given to the basic surveying square,
to a unit of land surface, and to the Square of Pegasus."
We still retain the ancient iku as our AC- RE.
