Petrus Bonus was a late medieval alchemist. He is best known for his Precious Pearl or Precious New Pearl, an influential alchemical text composed sometime between 1330 and 1339. He was said to have been a physician at Ferrara in Italy, causing him to sometimes be known as Petrus Bonus of Ferrara or as Petrus Bonus the Lombard. An Introduction to the Divine Art is also attributed to him but was printed much later, in 1572.
