“He was later banished by the same tyrant to the island of Patmos, where he suffered great labours and had admirable illustrations and revelations and wrote the Apocalypse”. In all these stories he must have painted himself as old and venerable. I do not know what moved the great Albrecht Dürer to paint him as a young man in his Apocalypse (but the very learned Luis del Alcazar did not do so) because he was very old when he wrote his Gospel and Epistles, aged ninety years” […]. He is painted in a tight tunic and cloak, which I always paint white, for his purity, and the cloak is red”.

“Fue desterrado, después, por el mismo tirano a la isla Patmos, donde padeció grandes trabajos y tuvo admirables ilustraciones y revelaciones y escribió el Apocalipsi”. En todas estas historias se ha de pintar anciano y venerable. No sé qué movió al gran Alberto Durero a pintarlo mozo en su Apocalipsi (non lo hizo así el doctísimo Luis del Alcázar) porque entonces era de muncha edad cuando escribió, de noventa años, su Evangelio y Epistolas”; […] Pintese con túnica ceñida y manto, la cual yo pinto siempre blanca, por su pureza y el manto, roxo.”
