Revelation of the true authors behind Villalons books and manuscripts

Lucena was a man of many languages. Being Judeoconverso and son of Ambassador Juan Ramirez de Lucena he knew Hebrew. He also had to master Greek and Latin for his studies. Then his international trips forced him to know Italian, Portuguese, and French. He was the ideal man to write Gramatica Castellana. Since several works of Cristobal de Villalon are giving problems as we do not know whether he was their real author, this work can hopefully clarify somewhat certain unknown territories.
