Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

Digitizing the Vatican Library

Fr. David Friel · January 15, 2020

Manuscript pageORKING with manuscripts has long been a labor limited to those with the time and resources to travel to libraries around the globe. In recent years, this has slowly begun to change, as more and more libraries have begun to make their collections available online. Such digitization projects are complex, so publishing an entire library online does not happen overnight. One very important collection that continues to expand its online offerings is the Vatican Apostolic Library (VAT).

Launched in 2010, the digitization of the Vatican Library (known as DigiVatLib and available here) has comprehensive goals. Ultimately, the plan is to make the library’s entire manuscript collection available online. The collection includes 80,000 codices, which will translate to 40 million scanned images. The DigiVatLib project makes use of International Image Interoperability Framework (IIIF) technology, which not only makes its own resources accessible, but also enables these resources to be easily searched and compared alongside the treasures of other major collections.

Digitizing manuscript libraries serves two principal purposes. First, it accomplishes long-term preservation of the materials for future generations. Second, it opens the collection’s treasures to a broad audience of scholars and interested parties. Both of these missions are immensely valuable.

Perusing the Vatican collection online turns up not only mesmerizing manuscripts, but also a large collection of coins and medals. Other treasures to be explored include incunabula, archival materials, and graphic and printed materials.

The homepage of the Vatican Library is worth a visit in its own right, but the digital collections warrant special exploration. One decade into the project, the results are fascinating.

Taking a few moments (or countless hours!) to pore over DigiVatLib is sure to provoke questions, curiosities, and new interests.

    PDF • “Music List” (Sunday, 28 December)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Holy Family of Jesus, Mary, & Joseph (28 Dec. 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon are particularly gorgeous. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • “Music List” (Xmas Midnight Mass)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Christmas Midnight Mass (“Ad Missam In Nocte”). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is simple, but quite beautiful. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • “Music List” (4th Sunday of Advent)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 21 December 2025, which is the 4th Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is the famous “Roráte Coeli” and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

Quick Thoughts

    What does this mean? “Pre-Urbanite”
    One of the things informed critics have frequently praised vis-à-vis the Saint Jean de Brébeuf Hymnal has to do with its careful treatment of the ancient hymns vs. the “Urbanite” hymns. This topic I had believed to be fairly well understood—but I was wrong. The reason I thought people knew about it is simple; in the EDITIO VATICANA 1908 Graduale Romanum (as well as the 1913 Liber Antiphonarius) both versions are provided, right next to each other. You can see what I mean by examining this PDF file from the Roman Gradual of 1908. Most people still don’t understand that the Urbanite versions were never adopted by any priests or monks who sang the Divine Office each day. Switching would have required a massive amount of effort and money, because all the books would need to be changed.

    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

Random Quote

“Chants closely related to the readings should, of course, be appropriately transferred for use with these readings. For pastoral reasons also there is an option regarding the chants for the Proper of Seasons: namely, as circumstances suggest, to replace the text proper to a day with another text belonging to the same season.”

— Ordo Cantus Missae (1971)
