Stylometric Analysis (JGAAP) of the Lucena-Oviedo Circle: New Evidence on the Authorship of La Celestina (1475–1550).

Abstract: This paper presents preliminary results from advanced stylometric analysis using the Java Graphical Authorship Attribution Program (JGAAP). For over five centuries, the authorship of La Celestina has been attributed to Fernando de Rojas. However, our research demonstrates that the "hidden hand" belongs to the circle of Juan Ramírez de Lucena and his sons. The Lucena Clan: The intellectual core behind La Celestina consists of an interconnected group of humanists. This circle includes Juan Ramírez de Lucena (patriarch), Gonzalo Fernández de Oviedo (presumed son and central figure), Francisco López de Villalobos, Hernán Núñez (El Pinciano), Juan del Encina, Alonso de Proaza, Fernando de Rojas and Francesch Vicent. Ongoing research evaluates other presumed sons, such as Fernando de Rojas or Francesch Vicent, or potentially both. The influence of Antonio de Nebrija is also noted. Key Correction: Modern JGAAP analysis reveals that the 1496 Prohemio in the Arte de Poesía Castellana (traditionally attributed to Encina) was authored by Gonzalo Fernández de Oviedo (Ranking #1). This confirms the stylistic match with La Celestina.
