15th Century Illuminated Gregorian Chant Manuscript Leaves on Vellum For Sale

A stunning and rare piece of original 15th-century illuminated manuscript leaves, beautifully preserved and rich in sacred history. These vellum pages, once part of a medieval choir book (likely an antiphonary or gradual), contain Latin liturgical text and music, featuring square neume notation on red four-line staves.
Leaf One references Saint John the Apostle, including the well-known line “Discipulus ille quem diligebat Iesus” (“The disciple whom Jesus loved”), and is adorned with a large red and green illuminated initial \"H\". Rubricated lines (in red ink) emphasize the sacred readings.
Leaf Two contains verses of praise, with the chant “Spiritus et animae iustorum” (“The spirits and souls of the just…”), and a beautifully decorated red and blue initial \"C\" marking the beginning of “Laudate Dominum”. This page reflects themes tied to the Feast of All Saints or the Apostles.
