Johannes Peckham (or John Pecham) was born between 1220 and 1225 in Patcham in the county of Sussex. He received his school education at the abbey of Cluny in Lewes. He then studied in the art department of the Sorbonne in 1245. He completed his studies in Oxford under Roger Bacon among others. Returning to Paris, he devoted himself to theology under Bonaventura. Peckham entered the Franciscan order in 1250. From 1269 until 1271, he was "magister regens" at the Sorbonne. He stayed in Oxford in 1271, where he introduced the academic rite, to keep "disputationes de quodlibet." In 1275, he was named provincial of England for his order. Peckham participated with his quill at the general chapter of the Franciscan order in Padua in 1276. He was the first minorite to be named "Magister Sacri Palatii" (Master of the Sacred Palace; papal theologian) in the Vatican. On January 28, 1279, he was finally elected to succeed Robert Kilwardby as Archbishop of Canterbury and English Primate. He was a strict representative of Church discipline and released various anti-Averroistic and anti-Thomistic decretals. Peckham preached the Crusade in 1290. Besides his scholastic-theological writings, which are partially unedited, he composed essays on psychological and mathematic-physical questions, including the piece "Perspectivae communis libri tres. Iam postemto correcti ac figuris illustrati." In the history of theology, he stands out as a co-founder of the New Augustinian School of Scholasticism. Peckham died on December 8, 1292, at Mortlake Manor in Surrey County.
