In the course of writing I find one thing I keep coming back to is the idea of western culture using children's rhyme's as a way to teach or mock the world around us. Take, for instance, Ring Around The Rosie, which is a rhyme about the Black Plague.
The concept of ancient rhymes that may no longer be meaningful to the people singing or the audience is fascinating to me. I've also noticed how creepy they are when either Children are not the ones singing or when they are in a completely out-of-context situation.
To that end, I have an ancient rhyme from the world of The Ever War:
O' wonder, O' wonder, behold the wrath and thunder, yet a coursing we will go.
A coursing we will go. A coursing we will go. Hi-ho the merry-o a coursing we will go.
Over hill, over dale, through the rain and twixt the hail, a coursing we will go.
