Time travel

A spirit thrust me to the Middle Ages

When kings and vassals all set sail

On a holy crusade with knights and pages

To the east in search of the Holy Grail.

"My liege," I asked, "will we kill and ravage?

Is not taking life a profanity?"

"No problem, Joe, collateral damage

We are advancing our faith, Christianity."

Is it king or country to which I am bound?

Do I close my eyes and follow along?

Can I search until the truth is found?

Is it possible that the king is wrong?

I now find myself on foreign soil

With a premonition that's hard to believe.

The Holy Grail is a hoard of oil.

That being so, I must take my leave.
