Antiphonary16th centurylatIntroitus for the Mass for the feast of two or more martyrs outside of Eastertide, to be inserted into a GradualIn Latin.Script: copied by two hands, both writing Southern Gothica Textualis Formata with Spanish features. Hand A copied the four upper lines on f. 1r in a regular handwriting; hand B copied all the rest over erasure in a more artificial handwriting, which is of exceptionally large size on f. 1r. Musical notation in black nota quadrata. Red rubrics in the four upper lines on f. 1r. A large cadel D on the verso (“Deus”). F. 1r has rich decoration in a style influenced by Ghent-Bruges illumination: large historiated initial (2 staves + 2 lines of text) with the seated Virgin and the naked Christ child standing on her lap; at right a soldier in armour holding a lance (an illustration of the “Miracle of the Knight of Cologne”). Full architectural border subdivided in niches containing personages; in the left-hand border Sts. Andrew, Paul, Philip, and James the Less; in the lower section Jeremiah and Zechariah, flanking a central panel containing two angels holding a cloth displaying the Five Wounds of Christ with the motto “Miserere mei”; in the right-hand border four angels holding trumpets; in the top section a row of roses between twisted branches.Originally the text, beginning with the initial, was that of the Antiphon “Sacerdos et pontifex”, sung at Vespers on the feast of a confessor bishop. It was erased and replaced with the current text, which is the Introitus for the Mass for the feast of two or more martyrs outside of Eastertide. The rubric at the top of the page and the initial were not erased, although they did not fit any longer the text. So the leaf originally was part of an Antiphonary, but it was removed and rewritten to be inserted into a Gradual.
