Chpt 2.19-20

On perceiving it the curate begged the notary to bear witness that Alonso Quixano the Good, commonly called Don Quixote of La Mancha, had passed away from this present life, and died naturally; and said he desired this testimony in order to remove the possibility of any other author save Cide Hamete Benengeli bringing him to life again falsely and making interminable stories out of his achievements.†
