A new source for Dominicus Gundissalinus's account of the science of the stars?

Summary

One source for the accounts of astrology and astronomy in Gundissalinus's De divisione philosophiae might have been an introduction to the science of the stars influenced by, if not originating from, the School of Chartres. This introduction survives in slightly different forms in three manuscripts, and is edited, along with Gundissalinus's chapters on astronomy and astrology, in the Appendix.
