Back to Benin: Brazil's slave and voodoo ties
15 May 2013 Last updated at 19:14 BST
A recent Brazilian film entitled Pedra da Memoria (Memory's Stone), follows the journey of a prominent Afro-Brazilian priest to Benin where many of Brazil's former slaves came from.
While visiting the Brazilian city of Sao Luis, BBC Africa's Manuel Toledo saw the documentary and a photo exhibition about the journey at a local museum.
He managed to track down the priest, father Euclides Talabyan, and the film-maker, Renata Amaral.
The music used in this radio piece, as well as the picture above, come from the documentary.
