Note 2787 — Chapter XXX · GERBERT AND THE INTRODUCTION OF ARABIC ASTROLOGY
Reading edition
Additional 17,808, a narrow folio in vellum with all the treatises written in the same large, plain hand with few abbreviations. A considerable part of the MS is occupied by the work on music of Guido of Arezzo (c. 995-1050). This MS is not noted by Wickersheimer or by Bubnov, although it includes treatises on the abacus and the astrolabe which are perhaps by Gerbert.
