Note 2852 — Chapter XXX · GERBERT AND THE INTRODUCTION OF ARABIC ASTROLOGY
Reading edition
Addit. 17808, fol. 99r-v. This does not appear in BN 17868 which goes on to discuss various astrological influences of the 12 hours of the day and of the night. After this there is a space left blank in the middle of fol. 12v: then more is said concerning hours of the planets and interrogations until at the bottom of fol. 13r comes the letter of Phethosiris to Nechepso. But no definite ending is indicated either of the letter of Argafalaus or the Liber Secundus of Alchandrus.
In a MS now missing but listed in the late 15th century catalogue of the MSS in the library of St. Augustine’s Abbey, Canterbury (No. 1172, James 332) was a “Breviarium alhandredi su’m astrologi et peritissimi de soia (scienda?) qualibet ignota nullo decrete.” This was one of the MSS donated to the monastery by John of London.
BN 4161, 16th century, #5, Breviarium Alhandriae, summi Astrologi de scientia qualiter ignota nullo indicante investigari possit.
