On Flatulence

It’s commonly held that farts are methane.
While this is true for cows, sheep, goats
and other herbivores, it’s not for humans.
Our flatus (that’s the word, I looked it up)
is largely hydrogen, lighter than air.

So the story of the Persian Prince
with noteworthy and continuous flatulence,
who is supposed to have suffocated himself
while asleep on a low bed-pallet on a trip abroad,
could not have happened.

However, should an equerry have brought a lamp,
a naked flame into the chamber,
his highness, without rising from his sleep,
could have raised the roof.
I think that trumps the suffocation story.
