Pentagram

The pentagram first seems to have appeared on cave walls and
it may of been used by various cults in pre-history.

Its association with Pythagoras in 500 BC is well
documented. He used it to make himself some super
math leader in his own cult.

If the Hexagon was to represent the Sun, then the pentagram
was to represent mankind. The five pointed star would be
worn by early Christians before they latched onto the cross.
It was to represent the five wounds of Christ. Later would
also find association by of the Trinity according to Brewers.
The three triangles that make up the pentagram being
the Trinity.

The Trinity as opposed to Duality and Unity was to be
the Father the Son and the Holy ghost. This too though
can be found back in Egypt where the stages of the day
were divided up into the father and son. A god for every
occasion the ghost could fittingly equal life in the underworld.

The Pentagram's points were to have 5 planets placed on the
outside of it as people tried to tie in maths with the greater world.
As more planets came along they would be attached to the outskirts
of more shapes.

Later the shape of man was to be attached to the five points,
limbs and head. The five points are also equal the extremities on
one hand and it should be considered that ten fingers or two
pentagrams would equal one sixth of a hexagon that makes up
our 60 minutes.

The Pentagon inside the Hexagon. Man encircled by the Sun,
the Sun's orbit. 3, 4, 5, 6, sides and so forth. It would seem
the perfect sun and stars were to be associated with even
numbers while mankind was to be dealt the odd numbers.
Except when the wandering planets added up to an odd number.

It seems the Romans were to represent 5 as a V, most
likely to save space in notation but maybe they were also
drawing on earlier instances. Perhaps V had special powers.
Perhaps the ancients had given special meaning to mankind's
opposable thumb.
