In 2007 Kislak Fellow, Fr. David Orique from the University of Oregon, spent four months at the Library of Congress studying this Las Casas manuscript originally thought to have been written in 1528. Fr. Orique planned to research Las Casas’ epistemological development by comparing this document in the Kislak Collection with other Las Casas’ writings from 1516. Orique’s research indicates, however, that the letter was actually written in 1543. You can read his analysis and also his translation of the document by clicking the PDF.
