George Santayana - "A wall, a wall to hem the azure sphere" lyrics

A wall, a wall to hem the azure sphere, And hedge me in from the disconsolate hills! Give me but one of all the mountain rills, Enough of ocean in its voice I hear. Come no profane insatiate mortal near With the contagion of his pa**ionate ills; The smoke of battle all the valleys fills, Let the eternal sunlight greet me here. This spot is sacred to the deeper soul And to the piety that mocks no more. In nature's inmost heart is no uproar, None in this shrine; in peace the heavens roll, In peace the slow tides pulse from shore to shore, And ancient quiet broods from pole to pole.
