Here we see that, above the 3 lowest steps of the "winding stair" of the FC°,
representing the 3 "Blue Lodge" degrees of Freemasonry, there are 12 steps on the
stair case, divided into two sets, the first, of 5, representing the senses and the styles
of columns, and the second, of 7, representing the schools of learning. The sequence
of 3,5,7 will play into much of the Illuminati symbolism, because these numbers are
the first odd numbers, and also the lowest prime numbers.
