Petrus Bonus (Latin for "Peter the Good"; Italian: Pietro Antonio Boni)[1] was a late medieval alchemist.
An Introduction to the Divine Art (Introductio in Divinam Chemicae Artem) is also attributed to him but was printed much later, in 1572.
The author admits to having little practical expertise and rather tries to establish alchemy on authentically philosophical grounds and to integrate it into the medieval scientific canon.
[5] The text was first printed in Venice in 1546 by Giovanni Lacinio under the title Pretiosa margarita novella.
This edition included commentary by Janus Lacinius, a Franciscan from Calabria, who added extracts from other alchemical authorities, including Raymond Lull, al-Rasi, Albertus Magnus, Michael Scot, Arnaldus de Villanova.
