A Franciscan monk who nevertheless pioneered experimental optics and astronomy, Roger Bacon was nicknamed "Doctor Mirabilis" by his contemporaries because of his futuristic writings. Bacon was often at odds with the Church, particularly in his translation and commentary on Aristotle whose writings were then only available from Arabic sources. He attempted reform of the calendar and promoted astrology and alchemy and their application to medicine. This is a translation of one of his lesser textbooks, but it was still regarded as useful enough to reprint 400 years after his death.
