The construction of 4th-order magic square is detailed in a work titled "Kaksaputa", composed by the alchemist Nagarjuna around 10th century CE. All of the squares given by Nagarjuna are 4×4 magic squares, and one of them is called "Nagarjuniya" after him. Nagarjuna gave a method of constructing 4×4 magic square using a primary skeleton square, given an odd or even magic sum. Incidentally, the special Nagarjuniya square cannot be constructed from the method he expounds. The Nagarjuniya square is given below, and has the sum total of 100.
