In the Middle Ages magic squares were believed to give
protection against the plague!
In the 16th
Century, the Italian mathematician, Cardan,
made an extensive study of the properties of magic squares
and in the following century they were extensively studied
by several leading Japanese mathematicians.
During this century they have been used as amulets in
India, as well as been found in oriental fortune bowls and
medicine cups.
Even today they are widespread in Tibet, (appearing in the
“Wheel of Life) and in other countries such as Malaysia,
that have close connections with China and India.
