CAN SOMEONE HELP ME IN STARTING A NARRATIVE POEM IN THE ANGLO-SAXON STYLE OF BEOWULF?

Answer 1

The narrative style in that poem is the story teller was all knowing, even knowing things the characters did not know. Narrative poems have a plot.

See the narration by the all knowing?

Now read The Raven, by Poe. http://www.heise.de/ix/raven/Literature/Lore/TheRaven.html

Almost the same style.

So outline a plot in your mind, and start to write.
