The Sator Formula
Source: Cavendish's The Black Arts

One of he most famous of all magick squares, is the Sator Formula:

S A T O R
A R E P O
T E N E T
O P E R A
R O T A S

It is said that this magic square was believed to be able to:
- find witches,
- protect cow's milk against witchcraft,
- extinguish fire
- magically obtain anything you want (write these words in parchment with the blood of a Culver(pigeon) and bear it in thy left hand and ask what thou wilt and thou shalt have it ~ Bodleian Manuscript)

Several attempts of interpretation:
1. Arepo, the sower (sator), delays (tenet) the wheels (rotas) by his works (opera)
2. the sower is at the plough (arepo), the work accupies the wheels
3. the Creator (sator), slow-moving (arepo), maintains (tenet) His creations (opera) as vortices (rotas).

What or where - do you think he power of this magical square came from?
Anyone has worked with this formula and share you results please?
Other squares such as planetaries etc are also open for discussion.
