Document 5: Source: Testimony of Captain Diogo de Carvalho in the Inquisition trial of Luzia Pinta, a free Black woman from Angola, resident in Rio de Janeiro, Brazil, 1741.

I saw Luzia at the home of João Peixoto. There was a small altar with a canopy, and she had a curved knife in her hand, and was wearing a large ribbon tied on her head with the ends thrown backward in the style of an angel. And singing there with her were two other Black women, also from Angola, and an African man playing a small tambourine. And after two hours of playing and singing, Luzia became as if out of her mind, speaking things that no one understood. Many people who had come there to be cured were lying down on the floor, and she stepped over them various times. On these occasions it was said that she had the winds of divination, and she said that God told her on these occasions what she was to do. She also cured the wife of João do Valle. I also heard that many times she had been called to go to other towns to cure people.

Where is Angola, and why would the author add this place?
