Of course the article is about the archaeological discovery, but if you're curious (as I was) what the poem is, it's "Caedmon’s Hymn":
"Now we must praise the protector of the heavenly kingdom
the might of the measurer and his mind’s purpose,
the work of the father of glory, as he for each of his wonders,
the eternal Lord, established a beginning.
He shaped first for the sons of the earth
heaven as a roof, the holy maker;
then the middle-world, mankind’s guardian,
the eternal Lord, made afterwards,
solid ground for men, the almighty Lord."
