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. Contents: ff. 1v-11v: Guido of Arezzo,
