Magic squares are squares which are divided into parts with each part becoming a square within the larger square. A number or letter, supposedly having magical properties, is assigned to each square within the square, and when read horizontally, vertically or diagonally the same sums or words are produced.
During ancient times in China, India and Arabia magic squares were used in practices of occult, magic and astrology. They have been and still are worn as amulets for protection.
In present times some mathematicians have discovered mathematical properties in the magical squares, especially those of larger configurations. A.G.H.
