Now, Odin had never been introduced to Heimdall--had never even seen him before; but he did not pass him by without speaking on that account. On the contrary, being altogether much struck by his appearance, he could not refrain from asking him a few questions. First, he requested to know whom he had the pleasure of addressing; secondly, who his parents were, and what his education had been; and thirdly, how he explained his present circumstances and occupation. "My name is Heimdall," answered the guardian of Bifröst, "and the son of nine sisters am I. Born in the beginning of time, at the boundaries of the earth, I was fed on the strength of the earth and the cold sea. My training, moreover, was so perfect, that I now need no more sleep than a bird. I can see for a hundred miles around me as well by night as by day; I can hear the grass growing and the wool on the backs of sheep. I can blow mightily my horn Giallar, and I for ever guard the tremulous bridge-head against monsters, giants, iron witches, and dwarfs." Then asked Odin, gravely, "Is it also forbidden to the Æsir to pass this way, Heimdall? Must you guard Bifröst, also, against them?" "Assuredly not," answered Heimdall. "All Æsir and heroes are free to tread its trembling, many-coloured pavement, and they will do well to tread it, for above the arch's summit I know that the Urda fountain springs; rises, and falls, in a perpetual glitter, and by its sacred waters the Nornir dwell--those three mysterious, mighty maidens, through whose cold fingers run the golden threads of Time." "Enough, Heimdall," answered Odin. "Tomorrow we will come." PART V. BIFRÖST, URDA, AND THE NORNS. Odin departed from Heimdall, and went on his way, Fenrir obediently following, though not now much noticed by his captor, who pondered over the new wonders of which he had heard. "Bifröst, Urda, and the Norns--what can they mean?"
