Famous quotes containing the words primitive and/or pit:
“That primitive head
So ambitiously vast,
Yet so rude in its art,
Is as easily read
For the woes of the past
As a clinical chart.”
—Robert Frost (1874–1963)
“I respect the ways of old folks, but the blood of a rooster or a goat cannot turn the seasons, change the course of the clouds and fill them up with water like bladders. The other night, at the ceremony for Legba, I danced and sang my fill: I am a black man, no? and I enjoyed it like a true Negro should. When the drums beat, I feel it in the pit of my stomach, I feel the itch in my hips and up and down my legs, I have got to join the party. But that is all.”
—Jacques Roumain (1907–1945)
