As I noted in an article last week, the Abbey of St Denis near Paris had the custom of celebrating Mass in Greek on the octave day of its patron Saint, a custom which was maintained until the French Revolution. This was not the Byzantine Divine Liturgy, but the Mass of the Roman Rite translated into Greek, although the Canon and other silent parts of the Mass remained in Latin. The website of the Schola Sainte-Cécile has just made available in pdf the complete text of a work published in 1779, which gives an historical introduction to this tradition, followed by the ordinary of the Mass in Latin and French, and then the liturgical texts of the Greek Mass, including the chant. All of the following, which explains the orgins of this custom in much greater detail, comes from the article which accompanies it, written by Henri de Villiers.
As an example of the chant, here is the introit of the Greek Mass from the 1779 edition:
Compare this with the original:
The parts of the Latin Mass have been translated into Greek, and set to the same chant, with some adjustments for the change in accent.
The whole Mass of the octave was chanted in Greek; however, on the octave, the Epistle and Gospel were repeated in Latin, while on the feast day, they were sung first in Latin, and then repeated in Greek. This custom of doing the readings twice goes back to the Carolingian era, and was also done on Easter, Christmas, Pentecost, the feast of St Matthias, and that of the abbey’s dedication on February 24th. (Mercure de France, 1728).
The work linked above is the second edition, after a first issued in 1777, and was clearly made to help the faithful to follow the Mass. Various witnesses of the 17th and 18th centuries attest that this unusual celebration, which was done with great magnificence and a large number of ministers in sacred vestments, was attended by large numbers of pilgrims, especially since, for the entire octave, the abbey would solemnly expose the relic of St Denis’ head, and the silver reliquary which contained his body and that of his companions, Ss Rusticus and Eleutherius, for the veneration of the faithful.
There is also a fragment of the Gloria written in the same fashion in a sacramentary (Laon 118 f° 145v°) which the monks of Saint-Denis made in the later part of the 9th century or beginning of the 10th, and gave to the chapter of Laon as a gesture of thanksgiving for taking them in during a Norman invasion.
The second book which we have from St Denis is a missal written between 1041 and 1060 (BnF Latin 9436), which at the beginning has several parts of the ordinary in Greek and Latin, and also their musical notation in campo aperto (i.e., with notes, but no staff): three Kyries, a Gloria in Greek, followed by three others in Latin, and the Credo in Greek (but not in Latin!), then three each of the Sanctus and Agnus Dei in Latin only.
Another very notable rarity is the Cherubic hymn, one of the most famous pieces of the Byzantine Divine Liturgy, translated into Latin to be used as a second Offertory at the Mass of the Trinity (f° 58v°).
“Qui cherubin mystice imitamur et vivifice Trinitatis ter sanctum hymnum offerimus, omnem nunc mundanam deponamus sollicitudinem sicuti regem omnium suscepturi cui ab angelicis invisibiliter ministratur ordinibus, alleluia. – We, who mystically represent the Cherubim, and chant the thrice-holy hymn to the Life-giving Trinity, let us set aside the cares of life, that we may receive the King of all, Who comes invisibly escorted by the Divine Hosts.”
The following is a reconstruction of it, since there is no manuscript which gives this version on staff notation.

The origin of the Greek Mass of St Denis
The oldest surviving liturgical book from the royal abbey of Saint-Denis is a sacramentary of the second half of the ninth century, (BnF Latin 2290), at the beginning of which we find the Gloria, Creed, Sanctus and Agnus Dei in the Greek language, but written with Latin letters, and with the Latin text added between the lines.There is also a fragment of the Gloria written in the same fashion in a sacramentary (Laon 118 f° 145v°) which the monks of Saint-Denis made in the later part of the 9th century or beginning of the 10th, and gave to the chapter of Laon as a gesture of thanksgiving for taking them in during a Norman invasion.
The second book which we have from St Denis is a missal written between 1041 and 1060 (BnF Latin 9436), which at the beginning has several parts of the ordinary in Greek and Latin, and also their musical notation in campo aperto (i.e., with notes, but no staff): three Kyries, a Gloria in Greek, followed by three others in Latin, and the Credo in Greek (but not in Latin!), then three each of the Sanctus and Agnus Dei in Latin only.
