But an even more important feature of Futhark - is that its structure repeats the idea of our Indo-European ancestors about the structure of the world. Each rune corresponds with its archetype, image and meaning; its name refers to one of the parts of the universe, and their complete set describes a comprehensive, integrated system of everything that occurs in the universe (which consists, according to the beliefs of Nords, of the nine worlds). The structure of 24 runes is divided equally into three parts, called atts. The runes within each att follow a strict order and their sequence tells a coherent story about the Earth and Heaven, about creation, life and rebirth, about the gods and chthonic beings - and of course about man. About male and female, love, power and death, sacrifice and well-being, exploit and joy.
