P-Cug (Coimbra) Biblioteca Geral da Universidade MM 049 [capa] + ...
Tones for Psalms, Introit Psalm Verses, and Responsory Verses.
On Fragment Br1 (MM 236d) someone pencilled in modern times an index of polyphonic works, possibly found in the codex that these fragments covered.
MM49 Contains a rare chant, based on Proverbs 30:18, a passage commented upon by several theologians, but found here in reverse order: Quartum penitus ignoro cum sint tria difficilia mihi. As the chant appears after the third tone (which may have started on the strip of parchment glued on top of fol. Ev: Tertius tonus sic incipit), it may be intended as a newly-composed illustration of the fourth mode (in spite of the high C), as suggested by the rubric: D[emons]tratio [...] modi. MM234 is apparently composed of two fragments from different books. One of them, with square notation, is related to MM49 above. The other, with semi-mensural notation, includes the hymn Hostis herodes impie (CAO 8248), for Epiphany, and is related to MM50 / MM51. MM236 comes from the same book as MM49 and MM234; it contains a newly-composed chant in fifth mode, Quintum sigillum cum aperuisset vidi subtus..., based on a passage from the Apocalypse, 6:9, with the order of the text reversed. MM243 consists of apparently two fragments from different books. The outer fragment corresponds to MM233. The inner fragment comes from the same Tonary as do three fragments above (MM49, MM234, MM236). The presence in this Tonary of new compositions freely based on Biblical texts usually removed from liturgical experience suggests a scholarly and reform-minded environment, such as that encountered at Santa Cruz de Coimbra in the second quarter of the 16th century.
Square notation with oblique pes and scandicus, and use of custos, over red pentagram (Iberian traits). Semi-mensural notation with square and lozenge shapes. For the mensural notation on a section of fol. Cr1, see MM0233 (capa) + MM0234 (capa).
