IM-10505: (550 x 390mm 21 5/8 x 15 1/4'') Original manuscript leaf from a manuscript Antiphonal. This beautiful four-line stave musical sheet is on animal parchment, written in liturgical gothic script. Six lines of music and text. Italy (Bologna), c. 1470-80.
One exceptional illuminated initial ''O'' in red and green. The interior is a floral design in green, red, blue and sepia on a deep blue ground; the initial sets on a burnished gold ground and continues into the margin. Three illuminated initials alternating in red with delicate violet penwork and deep blue with delicate red penwork. Numerous initials heightened with yellow.
The illuminated ''O'' begins: "O Beatum..." (O how blessed a man is he! His soul hath entered into possession in Paradise. There the Angels cry aloud for joy, there the Archangels make glad, there the whole company of the Saints do shout, there the army of the Virgins do call others to follow, saying: Make thine everlasting abode with us).
