 In contrast to the "Summary", the Young Man's other works show considerable originality.Historian L. P. Harvey proposed that the Young Man of Arévalo might have been the same person as Agustín de Ribera, a Morisco from Arévalo who claimed to be a prophet and had the epithet of "el mozo" (the lad), although he admitted that the theory had a lot of difficulties that he had not resolved.Agustín was arrested by the Spanish Inquisition in 1540 and records from his interrogation survived.
