Answer:

A magic square is an arrangement of numbers in a square so that each of the rows and columns and two diagonals have the same total. Often the numbers from 1 to 9 or 1 to 16, etc. are used, but other sets of numbers can be used. The 3 x 3 magic square was used as part of rituals in India from vedic times, and continues to be used till date. A well known early 4 x 4 magic square in India can be seen in Khajuraho in the Parshvanath Jain temple. It dates from the 10th century.

7	12	1	14
2	13	8	11
16	3	10	5
9	6	15	4

This is referred to as the Chautisa Yantra, since each sub-square sums to 34.
