Joe McGowan quotes a verse from a traditional island song commemorating the fate meted out to the violator of the altar's sanctity:
"The mystic flag that lights the sod profaned long, long ago,
The heretic did not believe consumed for doing so.
His bones lie there to tell the tale exposed for ages past
He expiated for his crime and there met with his last."
