About this source
What it is
This title page introduces the Comentarios, the second part of the 1555 printing of La relación y comentarios. It was written by Pero Hernández, secretary of the Río de la Plata province, acting under Álvar Núñez Cabeza de Vaca's direction. It covers his time as adelantado and governor in South America. The copy shown is held by Houghton Library, Harvard University.
Why it matters
Because it was written to defend Cabeza de Vaca's conduct as governor, including his dealings with the Guaraní people, it shows how he and his secretary tried to shape public memory of a controversial rule that ended in his arrest. It is as much a defense document as a history.
Look closer
- Why might Cabeza de Vaca have had his secretary write this defense rather than writing it himself?
- What does dedicating the book to a royal prince suggest about its purpose?
- Whose voices about the Guaraní are missing from this account?
