The Negro Speaks of Rivers by Langston Hughes I've known rivers:
I've known rivers ancient as the world and older than the flow of human blood in human veins.
My soul has grown deep like the rivers. 1 bathed in the Euphrates when dawns were young
I built my hut near the Congo and it lulled me to sleep.
I looked upon the Nile and raised the pyramids above it.
I heard the singing of the Mississippi when Abe Lincoln went down to New Orleans, and I've seen its muddy bosom turn all golden in the sunset.
I've known rivers:
Ancient, dusky rivers.
My soul has grown deep like the rivers
