Two Trips to Gorilla Land and the Cataracts of the Congo, by Richard F. Burton

“Allí o mui grande reino está de Congo,

Por nós ja convertido à fé de Christo,

Por onde o Zaire passa claro e longo,

Rio pelos antiguos nunca visto.”

“Here lies the Congo kingdom, great and strong,

Already led by us to Christian ways;

Where flows Zaïre, the river clear and long,

A stream unseen by men of olden days.”

The Lusiada, V. 13.
