Famous John Peckham Quotes

“[Perspectiva communis was written to] compress into concise summaries the teachings of perspective, which [in existing treatises] are presented with great obscurity.”

John Peckham

as quoted by John Freely, Before Gaileo: The Birth of Modern Science in Medieval Europe (2012)

“Among all the studies of natural causes and reasons, light most delights the contemplators”

John Peckham

Perspectiva communis, translated by, and appearing in the notebooks (C.A.<sub>543r</sub>) of Leonardo da Vinci, as quoted by Martin Kemp, Leonardo Da Vinci: The Marvellous Works of Nature and Man (2006) p. 112.
Context: Among all the studies of natural causes and reasons, light most delights the contemplators; among the great things of mathematics, the certainty of its demonstrations most illustriously elevates the minds of its investigators; perspective must therefore be preferred to all human discourses and disciplines, in the study in which radiant lines are expounded by means of demonstrations and in which the glory is found not only of mathematics, but also physics: it is adorned with the flowers of one and the other.

“Formerly the Church with its prelates of old time, was golden in wisdom, silver in cleanness of life, brazen in eloquence, which are three things needful to a preacher”

John Peckham

De Oculo Morali quoted in Georg Herzfeld (ed.) An Old English Martyrology (1900)
Context: Formerly the Church with its prelates of old time, was golden in wisdom, silver in cleanness of life, brazen in eloquence, which are three things needful to a preacher; that is, brightness of wisdom, cleanness of life, and sonorousness of eloquence. But of the feet, the last, that is the modern prelates, part is iron through their hardness of heart, and part is clay by their carnal luxury.

“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

Note the assumption that the heavenly sphere is concave with respect to the earth.
Perspectiva communis as quoted in J. D. North, Stars, Mind and Fate: Essays in Ancient and Mediaeval Cosmology (1989) citing D.C. Lindberg, John Pecham and the Science of Optics: Perspectiva communis (1970) p.99

“As you see double if you push the eye out of its place with your finger; so prelates, through evil counsel, judge a priest to be worthy of two benefices, when he ought to be contented with one.”

John Peckham

De Oculo Morali quoted in Georg Herzfeld (ed.) An Old English Martyrology (1900)

“And therefore, Sire, altho' I am ready, so far as is in me, to dedicate the place for the Cistercian monks at Meynan, yet I could not do it without the full assent of the bishop and of his chapter, and of the parson of the place, who, with plenty of other people, have a very great horror of the approach of the forsaid monks. For though they may be good men, if God please, still they are the hardest neighbours that prelates and parsons could have. For where they plant their foot, they destroy towns, take away tithes, and curtail by their privileges all the power of prelacy.”

John Peckham

Footnote: Mr. Martin [editor] remarks upon this letter: "The avarice of the Cistercians had already been noticed by Richard I., who, when accused of having at home three daughters whom he loved more than the grace of God, viz., Pride, Luxury, and Avarice, replied: 'No, they are no longer at home. My daughter Pride I have married to the Templars, Luxury to the Black Monks, and Avarice to the White Monks.'" (Pref. to Vol. II., Peckham's Register p. lviii.)
