Y’all need a break from C19 and Flynn at the moment. I know I do. Cross-posted at Assistant Village Idiot, as usual.
We think of poetry as a decorative art, important for beauty and the expression of elusive ideas in a strong or vivid manner. This is true of some early poetry, but many cultures used poetry more functionally. The point was to tell a story, an important story to preserve history. What strike us as decorative items now, such as rhyme or meter, were put there as aids to memory. The poet could not write things down, and did not want to falter or get lost over many passages. Structure locks these in. We still see this even in our literate culture. Children learn the states of the union as a song “There’s AL-abama, AL-aska…Rhode Island, Tennessee!” I have heard at least three songs teaching the books of the Bible: “I’ll tell you the truth about the book of Ruth…There’s Ezra, Nehemiah, Esther and Job I want to go to heaven in a righteous robe…” (and that was just from overhearing my sons). It is not unusual for adults in Bible study to laughingly mention that much of their memorized Scripture is from music. (Note: Handel’s Messiah is excellent for this.)
Telling a story in poetry happens less often these last two centuries. Rudyard Kipling would do it, Tennyson. When story is attempted now, however, the intent is often comic. We don’t allow songs to go on at story length very much these days. But we do see the memory advantage of this, don’t we? “Bumpty, bumpty, bumpty bright, BUMPity, bumpty, bump tonight!” And if you get lost, having to slur a few syllables, you can get right back on the horse next line.
