Interesting item from a piece on Woody Guthrie, inter alia:
[The ancient Roman poet] Virgil could sit and speak in iambic pentameter, like a modern rap artist. Woody could do the same thing. He could speak in poetry.”
I’ve never heard that about Vergil before … anyone know of a source?

Most actors with a specialty in Shakespeare can improvise pentameter ad-lib (e.g., after an accident on stage: “Thou canst not say I did not fall for thee.”), and I have seen, myself, a lunatic proclaim the Earl of Oxford wrote the plays because Elizabethan nobles all conducted conversations in blank verse .
Vergil, however, is hardly the same, whose forte is in dactyls. Did he write in iambics at all? If he did, I don’t know it.
