The Return of the King What's Up With the Epigraph?

Here's the epigraph for The Return of the King, which, if you've read The Fellowship of the Ring and Two Towers, you're no doubt familiar with:

Three Rings for the Elven-kings under the sky,
Seven for the Dwarf-lords in their halls of stone,
Nine for the Mortal Men doomed to die,
One for the Dark Lord on his dark throne
In the Land of Mordor where the Shadows lie.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the Land of Mordor where the Shadows lie.
