XVIII
—O Baths of Caracalla, arches clad
In such transcendent rhapsodies of green
That one might guess the sprites of spring were glad
For your majestic ruin, yours the scene,
The illuminating air of sense and thought;
And yours the enchanted light, O skies of Rome,
Where the giant vision into form was wrought;
Beneath your blazing dome
The intensest song our language ever knew
Beat up exhaustless to the blinding blue!—
