Tent of Miracles By Jorge Amado.

(Tenda dos Milagres) Translated by Barbara Shelby

Tent of Miracles is a Brazilian Modernist novel by Jorge Amado, written in 1969. It chronicles the chaos that results when a prominent American Nobel Prize winner arrives in Bahia, with nothing but praise on his lips for a long-forgotten local writer-scientist named Pedro Arcanjo.

When the media finally discover who Arcanjo was and what he espoused, they are completely horrified to discover that he believed that the way to improve the lot of humanity was for people of various races to marry and have children by one another in mixed-race marriages.
