Classic Poem

I heard a woman's voice that wailed
Between the sand hills and the sea:
The famished sea-bird past me sailed
Into the dim infinity.

I stood on boundless, rainy moors:
Far off I saw a great rock loom;
The grey dawn smote its iron doors;
And then I knew it was a tomb.

Two queenly shapes before the grate
Watched, couchant on the barren ground;
Two regal shades in ruined state,
One Gael, one Norman; both discrowned.
