Description
  • This manuscript contains a collection of scientific works. It opens with treatises on music by the Italian Benedictine monk Guido of Arezzo (b. c. 995, d. 1050) that were highly influential in the development of polyphonic music and staff notation. The section on music is followed by works on arithmetic and astronomy, particularly concerning the astrolabe, and astrology. The manuscript is an important witness to the fact that Arabic science had already permeated Western European culture before the 12th century. The manuscript includes astronomical terminology drawn from Arabic (e.g. names of constellations) and the Liber Alchandrei (The Book of Alchandreus). The latter is a work on astrology that is attributed Alchandreus, who is introduced as a 'supreme astrologer' although his existence has not been verified. The Liber is thought to have been translated into Latin from the Arabic in the 10 th century.
