" The other sources, even when they mention Hel, rarely describe it. But when they do, it's cast in neutral or even positive terms. For example, the mention that the land of the dead is "green and beautiful" in Ibn Fadlan's account is mirrored in a passage from Saxo (The medieval Danish historian, as you likely recall). In Saxo's telling of the story of Hadding, the hero travels to the "Underworld" and finds a "fair land where green herbs grow when it is winter on earth." His companion even beheads a rooster just outside of that land and flings its carcass over the wall, at which point the bird cries out and comes back to life - a feat which is highly reminiscent of another detail from Ibn Fadlan, namely the beheading of a rooster and a hen whose bodies are then tossed into the dead man's boat shortly before it's set aflame. In both cases, the emphasis is on abundant life in the world of the dead, even when death and absence prevail on earth. "
