The first volume of the series draws on the Forrest-Heyther partbooks, preserved in Oxford's Bodleian Library. They are the source of a 6-part Festal Mass by Richard Alwood, written to an unknown cantus firmus and most unusually in duple notation throughout, and a Festal Mass, also in 6 parts and using the Advent antiphon Ave Maria as cantus, by Thomas Ashewell.
