The constant is 34.
In an 8x8 magic square, the sum of each row, column, and diagonal is the same, known as the magic constant. For an n x n magic square, the magic constant can be calculated using the formula ( M = \frac{n(n^2 + 1)}{2} ). For an 8x8 magic square, this gives ( M = \frac{8(64 + 1)}{2} = 260 ). Therefore, the sum in the 1st row of an 8x8 magic square is 260.
Magic squares have been a source of intrigue since the time of Pythagoras, and even before. You will find the following link useful.
MAGIC SQUARE is a square divided into equal squares, like a chess board, where in each individual square is placed one of a series of consecutive numbers from 1 up to the square of the number of cells in a side, in such a manner that the sum of the numbers in each row or column and in each diagonal is constant.

Albrecht Dürer drew a 'magic square' in his engraving 'Melencolia I'. But I do not think he invented it.
A 1-9 magic square must add to 15.
A normal 3x3 magic square has a sum of 15. So you subtract 3 from each number in the square.
