--The 500-stanza poem is closely modelled on the Elder Edda, a collection of Norse myths preserved in a 13th-century manuscript, a pedigree Christopher Tolkien described as "unknown territory" for most people.
"I dare say that a good many will be instantly put off by the very idea of 'long narrative poems in verse' and pursue it no further," he said. It was equally possible that their form will lend them an "unexpected impact," he continued.
"My hope is that some of those who appreciate and admire the works of my father will find it illuminating in respect of Old Norse poetry in general, in his own treatment of the fierce, passionate and mysterious legend, and in this further and little known aspect of him as both philologist and poet. Above all I hope they will take pleasure in this poetry."

btw, the hunt for gollum is really well done.
