heimdall is the watchman of the gods and guardian of bifrost, the rainbow bridge between midgard and asgard. he requires less sleep than a bird and can see a hundred miles around him, by night as well as by day. his hearing is so accurate that no sound escapes him. he can even hear the grass grow or the wool on a sheep’s back. his hall is himinbjorg (cliffs of heaven), and he owned the horn gjall, whose blast could be heard throughout the nine worlds. heimdall is associated with the sea and is the son of nine maidens (possibly nine waves). as the god rig, he created the three races of humans: the serfs, the peasants, and the warriors.
