Langston Hughes

I 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.

From The Negro Speaks of Rivers

This one just gives me shivers, and it really shows Hughes' skill as a a poet. The two African rivers are framed by the Asian river and the American river, focusing the poem on Africa, while conveying a sort of westward motion (i.e. starting from the dawn of civilization at the Euphrates and ending with the African in America with the Mississippi).
