The Heart. What theme had Homer but original sin?

The Soul. Seek out reality, leave things that seem.
The Heart. What, be a singer born and lack a theme?
The Soul. Isaiah's coal, what more can man desire?
The Heart. Struck dumb in the simplicity of fire!
The Soul. Look on that fire, salvation walks within.
The Heart. What theme had Homer but original sin?

William Butler Yeats
