Polyphony on 21 folios comprising ff. 132-152 in modern compilation of five originally separate, unrelated manuscripts (i + 168 folios, with modern pencil foliation, 1-168). Each manuscript is collection of individual folios or small gatherings, each containing different voice part. Only ff. 132-152 contain repertory within scope of present catalogue; other items not taken into further account here. Folios now preserved loose in modern folder/box of mottled green-black cardboard.
Signature of Petrus Alamire on f. 132v. Ff. 132-152 from the workshop of Alamire (Nowak 1948); Warmington distinguishes the hands of Alamire and scribe K, with text added by scribes F and Y. The unusual layout of the sheets (see Physical description), their size, calligraphy and careful underlay suggest these may have been performing parts; although it is possible they were models for the use of scribes in preparing choirbooks or partbooks.
Copied in Brussels/Mechlin; belongs to Netherlands court complex (KellJ). Subsequently owned by Raimund Fugger the Elder (1489-1535), of Augsburg. Fugger library purchased by Emperor Ferdinand III and brought to Vienna in 1656.
