Inverted polyphonic offsets on ff. 299-300 from three pages of a small choirbook, now lost. The offsets appear on blank flyleaves of the Bible. (Loose choirbook pages perhaps placed temporarily within Bible, resulting in offsets; no evidence that music pages ever bound into volume).
Bible copied in England. Purchased by Richard Hartón from executor of Johannis Grene (inscription on f. 300). Later owned by William Westbury (inscription on f. 4), Fellow of New College, Oxford; donated to New College by Westbury, probably after 1456. Now deposited in Bodleian Library.
