(Turges)-1, anon-20
At least 140 parchment fragments (37 of which contain music), of irregular shapes and widely varying sizes, recovered from wallpaper in rooms of New College, Oxford. Highly fragile condition; accessible for study, but not yet for photography. Music fragments apparently the only surviving remnants of two large choirbooks, one containing Masses, the other, Magnificats and votive antiphons. No original foliation remains.
Fragments provisionally arranged in eight folders, of which the first three contain music: 368/1-music fragments numbered by Roger Bowers, #1-7A, 7B-10, #21-22, #31-41 (# 37 consists of two fragments stuck together); 368/2 - smaller musical fragments, numbered #1-9; 368/3 -non-musical fragments with musical offsets, numbered #1-3. Modern inventory. Black mensural notation with red coloration (Magnificats and motets); black mensural notation with black void semiminims (Masses).
Ca. 1490 (Magnificats and motets); ca. 1510 (Masses). Probably copied in Oxford, for use by the New College chapel choir (Roger Bowers). Original manuscripts disassembled ca. 1550(?) and used as backing for painted decoration of ceiling beams in main quadrangle of New College. Fragments discovered and removed by decorators in early 1960's, then placed in New College Library; deposited in Bodleian Library in 1978.
