Description: 

This manuscript was reconstituted in the 1950s by Guiseppe Abate from parts of the former Assisi, Biblioteca comunale, 693 and Assisi, Biblioteca comunale, 694 (see Abate, 1960). A very similar gathering structure suggests that the two manuscripts were copied in the same scriptorium around the same time. An inventory of 1381 indicates that this manuscript (before reconsitution) was kept at the Sacro Convento in Assisi, but its location before this date is not known for certain.

The differentiae of each mode have been numbered with a two-digit system: an upper-case letter indicating the final pitch of the differentia and a sequentially ordered numeral. Differentiae that vary in terms only of immediately repeated notes, presence/absence of liquesence or neumation are give the same differentia code, but are distinguished with a lowercase letter in the first column of the “Extra” field (see the File Description).

Chants not found in CAO have been assigned arbitrary numbers beginning with "fra". The codes for differentiae and chants not found in CAO in this index are consistent with those used for the other Franciscan manuscripts in the database:
