This is one of the images from Dan Brown's novel, Angels and Demons. From every angle, the words earth, fire, air, and water are legible. In the book, this symbol is branded on someone's body after he is murdered by the group to whom the symbol belongs. Of course, this is gruesome and disturbing, but the image alone is beautiful because of its symmetry. In this case, symmetry seems to equal perfection. I think this is beautiful because perfection is attained in this image.
