Famous quotes containing the words primitive and/or pit:
“A township where one primitive forest waves above while another primitive forest rots below,—such a town is fitted to raise not only corn and potatoes, but poets and philosophers for the coming ages. In such a soil grew Homer and Confucius and the rest, and out of such a wilderness comes the Reformer eating locusts and wild honey.”
—Henry David Thoreau (1817–1862)
“Come gather round me players all:
Come praise Nineteen-Sixteen,
Those from the pit and gallery
Or from the painted scene
That fought in the Post Office
Or round the City Hall....”
—William Butler Yeats (1865–1939)
