Chapter LXX: Appendix: I

SOME MANUSCRIPTS OF THE LIBER ASTRONOMICUS OF GUIDO BONATTI

Boncompagni states that there are several MSS in the Bibliothèque Nationale at Paris and the following are noted in the old catalogue: of the 14th century, BN 7326 and 7327: of the 15th century BN 7328, 7329 (a fragment), 7441 (defective), 7442 (containing only the treatises on elections and revolutions), 7443 (only the treatise _De imbribus et aeris mutationibus_). Perhaps the following also has reference to Bonatti: BN 7316, 15th century, #20 (and last item), _Guidonis Bonafors liber abbreviatus per Fratrem Hugolinum de Faventia ordinis sancti Augustini qui ea tantum excerpsit quae ad astrologiam judiciariam pertinebant_.

Some MSS in English libraries are:

Savile 15 (Bernard 6561), a large MS in which it is the last
