Revisiting Authorship Attribution of Tirant lo Blanc Using Parts of Speech n-grams

Yoshifumi Kawasaki


Abstract
Tirant lo Blanc (TLB) is a masterpiece of medieval Catalan chivalric romance. Regarding its authorship, two hypotheses exist: the single-authorship hypothesis claims in agreement with the dedication that Joanot Martorell is the sole author, whereas the dual-authorship hypothesis alleges in line with the colophon that Martorell wrote the first three parts and Martí Joan de Galba added the fourth part. In this study, we revisit the unsettled authorship attribution of TLB with stylometric techniques; specifically, we exploit parts-of-speech (POS) n-grams as stylistic features to investigate stylistic differences (if any) across the work. Furthermore, we address the distinction between narration and conversation, which has previously been omitted. We performed exploratory multivariate analyses and demonstrated that, despite internal differences, single-authorship is more likely from a statistical point of view. If Galba had contributed something to the last quarter of the work, it would have been minimal.
