Copied by Luca Orfeo (inscription on f. 2). Copied in Rome, for use by Cappella Sistina.

Some folios in poor condition due to ink corrosion; some music now illegible.

Covers of medium brown leather over boards, blind tooled with decorative borders and central diamond motif; brass clasps, studs, and bosses. Covers date from 18th century (LlorCS), but decoration imitates earlier style; see VatS 13 for other manuscripts with similar bindings.

black void mensural

Staff height 28-32

Original ink foliation, ii-cxlviii, on upper right rectos (f. i now missing; 'lxxxviii' apparently applied to two consecutive folios, or one folio left unnumbered at this point). Modern pencil foliation, 1-148, on lower center rectos (excludes first and last flyleaves; '88' applied to two consecutive folios to maintain congruency with original foliation despite discrepancy noted above).

First Mass has illuminated initials (orange, light blue, yellow, red, gold) in plain block style on rectangular grounds (blue, red, green, purple, orange, yellow); a few inked calligraphic initials in remainder of manuscript.

Original index on f. 3 lists Masses in order of appearance.
