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.”

Exploring the 5th/6th-Century Mosaics of Ravenna

Fr. David Friel · February 23, 2020

Y CURRENT research project had me studying the stunning mosaics of Ravenna over the last two weeks. These artworks were not completely unknown to me, but I had never had the occasion to explore all the secondary literature that has been devoted to these mosaics. These magnificent images, crafted mostly in the fifth and sixth centuries, are not only attractive to behold, but also deeply theological.

For those who may be unfamiliar with these works of art, a good, concise introduction to the Ravenna churches is found here.

One of the most interesting pieces is the mosaic adorning the apse of Sant’Apollinare in Classe. The presence of Moses and Elijah make clear that the mosaic depicts the scene of the Transfiguration. The figure at the center, however, is not a radiant Christ in splendor, but rather a jeweled cross set in a blue orb. An excellent analysis of the details in this mosaic is found here.

Another masterpiece among the Ravenna mosaics is the set of panels adorning the nave walls of Sant’Apollinare Nuovo. These images show a procession of saints, bearing their gifts to the altar and, ultimately, to the enthroned Christ. The Gospel side of the nave features 22 virgins (all female), while the epistle side features 26 martyrs (all male).

The most architecturally interesting church in Ravenna is undoubtedly San Vitale, consecrated in the year 547. The basilica combines Roman and Byzantine elements. The basic floorplan consists of two concentric octagons, surmounted with a dome.

The apse within San Vitale presents an extraordinary program of interconnected mosaics. The central image displays Christ in Majesty, alongside St. Vitalis and Bishop Ecclesius. On either side of the apse, one finds mosaics of the Emperor Justinian and his Empress, Theodora. In order to understand how all the mosaics in the apse of San Vitale relate to one another, I highly recommend watching this video:

The cluster of Ravenna churches housing these mosaics stand as testimony to the beauty of ancient Christian faith. They also remind us not to fall into the all-too-easy trap of thinking that people living in ancient times were somehow primitive, unrefined, or unintelligent (a position encountered surprisingly often both in popular imagination and in historical studies).

The artist-theologians who crafted the mosaics of Ravenna still have much to teach.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

Quick Thoughts

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

Random Quote

“I prefer to say nothing, or very little, about the new calendar, the handiwork of a trio of maniacs who suppressed—with no good reason—Septuagesima and the Octave of Pentecost and who scattered three quarters of the Saints higgledy-piddledy, all based on notions of their own devising!”

— ‘Fr. Bouyer, Consilium member appointed by Pope Paul VI’
