A newly discovered Spanish description of Kongo increases our knowledge of the country, joining Filippo Pigafetta’s famous account to expand our knowledge of Kongo in this early period. This research shows that the MS was written in 1587 or 1588 and was written by Carmelite Diego de la Encarnación. It adds details on the history of the country, daily life culture, and links to other Carmelite works, including an unpublished chapter of an account by Diego de Santissimo Santo and shows the author could have written a longer but well-known account in the Vatican Library. It includes extensive quotations from the new text.
