## Magic Squares

(religion, spiritualism, and occult)

An arrangement of numbers in the form of a square so that every row and column, plus both diagonals, will add up to the same number. This number is called the constant. Each number may only appear once in the square. Magic squares have been known and used from ancient times, engraved on metal talismans and drawn on parchment ones. Used in ancient India and China, they were introduced into Europe early in the Christian era and have been found in many of the grimoires of Ceremonial Magic.

Heinrich Cornelius Agrippa von Nettesheim (1486-1535), best known simply as Cornelius Agrippa, founded several secret magical societies and wrote a number of books on magic. His best known work was De Occulta Philosophia (1531). He constructed seven different magic squares that he aligned with the seven planets: Saturn, Jupiter, Mars, Sun, Venus, Mercury, and Moon. These have become standards in ritual magic. The Saturn square is probably one of the oldest, being found in the Chinese I-Ching. Its constant is 15.

Francis Barrett in his The Magus (1801), Eliphas Levi in Transcendental Magic (1896), and others followed the lead of Agrippa, employing magic squares for a variety of purposes from protection in childbirth to making a man powerful. In 1932, S. L. MacGregor-Mathers published a translation of The Book of Sacred Magic of Abra-Melin, the Mage, purported to be the manuscript of a fifteenth-century grimoire. Much of the book is made up of magic squares for many different purposes, but the majority are comprised of letters rather than numbers. These are arranged so that the words read the same from the left, right, downward, and upward. One of these, known as the Sator formula, from the first word across the top of the square, was discovered engraved on old drinking vessels and on fragments from a Roman villa near Cirencester, England. It was believed that a witch could not stay in the same room as a talisman engraved with the Sator square.

Great care had to be exercised when constructing magic squares. When drawn on parchment, the squares should be marked in black ink with the numbers or letters in red ink. All should be drawn with the parchment set up so that the maker's shadow does not fall on the parchment. The red lines should not touch the black anywhere. As with all magical items, it should be appropriately consecrated before use.
