A bifolio, formerly the cover for documents stemming from the notarial archive of the district of Ceccano, approximately five miles south of Frosinone: this one was used as a cover for documents from 1523-25 copied by the notary Jacobellus Augustini Paniscaldi (protocollo 12 from Busta 3). The surviving foliation number of 217, written in arabic, reveals that this bifolio was once part of large manuscript.
The bifolio was unfolded and then refolded along its widths to form long, narrow cover for the notarial documents. Like certain of the Mancini folios which were used for similar purposes, this reuse has caused the loss of music along the middle of most pages. Most of the contents of the folio can, however, still be read. When refolded along the original (that is, music manuscript) fold, a single work is transmitted on each page. All four works survive incompletely.
Part of the same mansucript as I-FRs Collezione delle pergamene 266 (31); DIAMM also features [a reconstruction of the remains of the manuscript][2].
Foliation given in this inventory after Cuthbert (2006), 321: 'The foliation designed by Gialdroni and Ziino has the advantage of deemphasizing order among the folios—we do not know whether f. W precedes or follows f. X, for instance—but at the expense of removing connections between a folio’s recto and verso, and even calling some verso faces (containing only cantus voices) rectos.'
