"We have a more pleasant scene presented to us, when the archbishop revisited the place of his early education, and showed his affectionate respect to the aged men, once his superiors, now placed under his jurisdiction. The archbishop arrived at Lewes. The chapter of the priory went out to meet him. They experienced the strange feeling, which old men often experience, when they pay obeisance to one, whom they have whipped when a boy. The Archbishop of Canterbury, arrayed in his pontificals, and in great state, joined the procession as it perambulated the town of Lewes. He preached in the great church; he granted indulgences; he sang the mass at the high altar. Having thus done all that he could do for the honour of the priory; having kept a high festival and feasted the poor; Brother John, as he is called in the "Diary," put off his splendid attire, and in his grey coat, rope-girdle, bare of foot, he entered the refectory, and partook, with his usual moderation, of the simple fare of the delighted monks. To receive such a mark of respect from a friar, usually the opponent of the monks, was an honour highly appreciated."
John Peckham was a Franciscan friar and Archbishop of Canterbury in the years 1279–1292.
"The Perspectiva is a clear and concise summary of the science of light at the time... a popular text on optics until the seventeenth century... used and cited by many medieval and Renaissance scholars, including Leonardo da Vinci and Johannes Kepler."
John Peckham"Giambattista della Porta, who seems to have been the first to try combinations of lenses to form a microscope, based his optical work almost entirely on that of Roger Bacon, Witelo, and Pecham."
John Peckham"Light from a concave luminous body is received most powerfully at the centre. The reason for this is that, for every point of a concave body, perpendicular rays, which are stronger than others, converge in the centre. Therefore the virtues of celestial bodies are incident most powerfully in and near the centre of the world."
John Peckham"Pechams Perspectiva was published in as many as nine editions, one in Italian, between 1482 and 1627."
John Peckham"Another Oxford writer who appreciated experimental science was John Pecham... In his Perspectiva Communis Pecham gave a very clear and concise summary of contemporary optics, based largely on Alhazen, Witelo, and pseudo-Euclids De Speculis. His book contained nothing original but it remained a popular text book until the seventeenth century."
John Peckham"In the realm of psychology (in the medieval sense), Pechams writings are extensive. ...each soul is created singly and "daily" by God. The soul... is everywhere in its little world as God is everywhere in the the bigger world. The soul is united to the body as a form is to matter. ...The human will is free and cannot be coerced by anything else. ...The will is free to the extent that it can withhold consent to the dictates of practical reason."
