The Magic Square

I took a break from revision today after noon by constructing a 19 x 19 magic square. It turned out to be the most beautiful thing I created by hand. Behold!

It has numbers from 1 to 361 and it took exactly 20 minutes to build. That was better than I had expected. After all, I had to fill up the matrix so that each row column and diagonal gave a sum of  3439.
If you refuse to believe it I invite you to download the picture, enlarge it and utilize a calculator (or your brain) calculate the sum.
