"Hugin and Munin Each dawn take their flight Earth fields over; I fear me for Hugin Lest he come not back, But much more for Munin." Perhaps because of Munin being memory he was expected to fail first. Odin looking over into Niflheim, is thus alluded to in an old song. The god is made to say,-- "I know that I hung On a wind-rocked tree Nine whole nights. Downward I peered, To runes applied myself, Wailing learnt them, Then fell down thence." The next strophe tells how he got the draught of the precious mead. In this myth, it seems as if Odin hung upon Yggdrassil. Simrock mentions a singular little German tale which may possibly have some connection with it, and has evidently an Eastern origin. "A man," it says, "in danger of falling into a brook, held fast with one hand to a shrub whilst his feet rested on a small piece of grass. In this predicament, he saw two mice (day and night) gnawing at the root of the shrub, and the grass undermined by four worm heads. Then a dragon appeared and opened his mouth to swallow him up, whilst an elephant reached his trunk towards him. At the same time he seized with eager mouth some honey which dropt from the tree." Simrock says that the eating of the honey is like people being occupied with frivolity whilst the world-battle goes on, but may not the story possibly have a little to do with Odin and Yggdrassil and Odhærir. We heard before that Odin was connected with Air. We see him here on his High Throne looking over all worlds, wandering over the earth, piercing even to the deep, giving his eye to Mimer for wisdom--consequently having only one eye, one Sun in Heaven--some suppose that the pledged eye means the setting of the Sun nightly. Mimer, who guards the well, means the remembrance of the origin of things which was water--the strange waves that flowed into Ginnungagap. An odd story is told of Mimer, who was originally a giant though received by the Æsir, viz., that he was sent as a hostage to the Vanir, who cut off his head and sent it back to Odin. The head remained so wise that the father of the gods used to consult it on all important occasions; as the lay says-- "Odin speaks With Mim's head." Heimdall, guardian of the Bridge (whose exact name was "trembling rest") was perhaps the most important of the Vanir. He is represented in one old lay as travelling about the world by himself, which is a sure sign that he was originally a very great god indeed. Upon this journey he became the father of the three races of men, the Thralls, the Karls and the Jarls. The way in which these three races are compared with one another is very curious.
