‘Archaeology is the search for fact. Not truth. If it's truth you're interested in, Doctor Tyree's philosophy class is right down the hall’ (Indiana Jones and the Last Crusade).

Are you an archaeologist (or historian) or a philosopher (or songwriter)? Were you a historian I think we’d be concerned about a factual error, but the truth of your song is surely more important than one small factual detail. Anyway, I’m sure you can set the historical record straight in your intro/sleeve note.
