Single (framed) leaf from a print antiphoner, measuring 40.7 x 25.5 cm; writing area 36.0 x 21.1 cm. Numbered CXXXI in upper right. Five line moveable type staff with Hufnagel notation, both in black; red used for initials and rubrics. Uses both c and f clef (the latter with a zigzag shape), many diagonal dividing lines between words, and a distinctive four-line symbol at the conclusion of the first chant.
Part of a series of chant volumes ("Canto Gregoriano Mogutinus") published in Mainz by Küchler from 1665-1667; this is (likely) the Hebdomedarium, vol.1.
