The Anonymous Peterhouse Master and the Natural Philosophy of Plants
Early in the thirteenth century, probably within the first decade, a treatise on plants was translated from the Arabic by Alfred of Sareshel (or Alveredus Anglicus), which was to become the foundation of the science of botany for the Latin-speaking world. This treatise was until the sixteenth century universally ascribed to Aristotle and awarded all the authority accorded the Philosopher in the other sciences. Within a generation of the appearance of the Latin version the De plantis had become a set text in university curricula and by 1254 was prescribed by statute at the University of Paris as an examination subject. Roger Bacon was lecturing on the text at Paris already in the 1240s and a decade later Albert the Great was composing his monumental and never-to-be-surpassed commentary on the same text.
