The Last Years of Archbishop Pedro Moya de Contreras, 1586-1591
Any historian who sets out to write a book faces two dangers. The one might be called the “one more document syndrome,” the obsession with research that is so exhaustive that nothing further can be found. The other is the prospect of publishing a work, only to have further documentation come to light that was lacking in his original research or alters his conclusions. Perhaps the latter is the lesser danger because it at least permits part of the historical record to reach the public. It may be that I am prejudiced in that regard, having suffered this very experience. In a recent biography of Pedro Moya de Contreras, the first inquisitor of New Spain, third archbishop of Mexico, and interim viceroy, I wrote of his last years in Spain “one can only hope that future research and perhaps fortuitous discoveries will complete that part of his life's story.” The fortuitous discoveries were made within a few months after publication, happily by the author himself. They consist for the most part of a collection of documents in the library of the Instituto de Valencia de Don Juan in Madrid, especially the papers of Mateo Vázquez de Leca (1543-1591), Philip II's private secretary and an indefatigable hoarder of valuable documents.
