Number Symbolism

The number four is attributed to the Sun, significator of royalty,
of the king, exalted in Aries [that rules the head, and loves to be
at the head, as the chief, ruler and leader; as an 'emperor' too is
an exalted king, a king of kings]; the king rules through divine
providence, defender and protector of the faith, imposing divine law
and order. Though a king be temporal, the office as divinely ordained
is eternal, "the king is dead, long the king"; the baseline of the
triangular number 10, the end and beginning of a new cycle, the wheel
of fortune upon which kings rise, inherit and fall, as the sun rises
and falls through the day. It is the square root of 16, the
lightening struck tower, empires themselves rise and fall according
to divine providence. In Christian/Judaic interpretation of history
the destruction of empires is taken as the hand of God against those
that have transgressed the rule and order of god, and thus foregone
any divine right to rule.
