Hymnal manuscript, circa early 16th century

Early 16th-century manuscript hymnal, in Latin [Germany]: NP, ND (circa 1500s). Quarto (6 ^6/8 X 8 ^6/8 X 1"). Unpaginated. [96] leaves (ms from leaf 3 to leaf 91). Written in Germany, possibly in the area of Fulda, whose patron saints are Simplicius, Faustinus, and their sister Beatrix. The manuscript later passed to the Benedictine monastery of Amorbach, whose 17th or 18th-century ex-libris is on the upper margin on f.4. The manuscript contains numerous mentions of liturgical music (nocturnos (Nocturnes), laudes (Praises),  nona (None), vesperas (Vespers), and others), and the text, unique and never published (to our knowledge), is often accompanied with musical notations in top and bottom margins. The notes (neumes) are grouped around a five-line staff. The small size of this hymnal suggests that it was used privately when participating in the liturgy. Original blind-stamped leather over wooden panels, with four decorative brass corner pieces on each board, and a brass boss decoration at center. Original clasps missing. Handwritten title laid on spine.
