This illustration originally started out as to show
the incorrect alignment of the E and of the
sunship(as to)the upper end of the W solstice band,
and the correct alignment(as to)the center of the
Sun(and the 8° variance between the two), and in fact
does just that. After doing this, I found that the maker(s)
of the disc must have known how to work with pi, and
the relationships between(one)unit of circumference
to the next, per the scale at which all illustrations
within this website were done.
