The first part of this study of the ‘Gyffard’ partbooks (Lbl Add. MSS 17802–5) examined in detail the handwriting, watermarks and other aspects of their physical make-up, and concluded that the collection could not have been compiled sequentially, as had hitherto been imagined. Each book was seen to fall into seven fascicles, and arguments were advanced for the existence of three layers, labelled - for the sake of convenience - early, late and latest. A sequel was also promised in which the problems of scribe/ownership, date and provenance would be addressed. Before attempting to identify the person responsible for assembling the anthology, however, one would do well to examine the biographies of the composers there represented, for if it could be demonstrated that the work of certain composers associated with a particular locality was restricted largely to a particular layer of the collection, then such geographical and temporal co-ordinates might be of assistance in confirming the identity of the compiler if they were seen to reflect the pattern of his own associations and movements.
