Abstract: To help settle the debate around the authorship of Tirant lo Blanc, we analyse the evolution of the diversity of the vocabulary used in that book, as measured through eight different diversity indices. The exploratory analysis reveals a clear single shift in diversity, that is estimated through change-point techniques to be in chapter 382, and might indicate the existence of one main author writing about four fifths of the book, and of a second author finishing the last one fifth of the book. Before chapter 382, the language is richer and more diverse than after it.
