The Roman Breviary of St Pius V derives from the medieval use of the Papal Curia, which was traditionally very conservative in most regards, and especially so in its repertoire of hymns. Many feasts, including some of the greatest solemnities (e.g. Christmas and Epiphany), have only two proper hymns, one of which is sung at both Vespers and Matins, and the other at Lauds; the same is true of almost all of the common Offices. When the Office hymns were revised in the post-Conciliar reform, the corpus was considerably broadened by the addition of new texts, among them, a very nice hymn for the Ascension previously used only in the Ambrosian Rite and by the Cistercians. In the Liturgy of the Hours, it is appointed to be said at Lauds on the Ascension itself, and the days that follow until Pentecost.
The version used in this recording has several discrepancies from the one given in the table below, which I have taken from an Ambrosian Breviary printed in 1539. (The sung text and a French translation are given in the comments on YouTube.) The original form of the hymn given in volume 51 of the Analecta hymnica (p. 92) dates from the 10th century, possibly earlier, and has a number of metrical and grammatical flaws typical of that period. These were subsequently corrected in various ways; it was also reworked for use in the Liturgy of the Hours, somewhat less cack-handedly than usual. The English translation is taken from the second volume of Early Christian Hymns, by Daniel Joseph Donahue; it is fine as poetry, but not especially literal as a translation.
The first part of the hymn Optatus votis in an Ambrosian Breviary printed in Venice in 1539. The rubric at the top says “On the vigil of the Ascension of the Lord”; until the Tridentine reform, the term “vigil” was commonly used to mean “First Vespers” in both the Roman and Ambrosian Rites. |
A couple of the expressions used in this hymn show very nicely the ability of Latin to say a great deal with very few words, and perhaps call for some explanation. In the third stanza, “Victricis carnis gloriam”, literally means “the glory of the conquering flesh”, a very terse way of saying that the Incarnation, the taking on of our human nature in the flesh, was the means by which Christ both defeated the devil and raised us up to the glory of heaven. Likewise, in the fifth stanza, the unknown author called the Virgin Mary “our Virgin”, as a way of saying that She is the source from which our human nature is united to the divine nature.
As noted above, before the post-Conciliar reform, this hymn was used outside the Ambrosian Rite only by the Cistercians; there is an interesting story about how this came to be. Hymns were first introduced into the western Church by St Ambrose, and because of this, St Benedict in his Rule uses the term “ambrosianum” for them, rather than “hymnus.” When the Cistercians were founded at the end of the 11th century as an order which intended to follow the letter of the Rule as strictly as possible, they took this term to mean not “hymn” generically, but rather, the specific corpus of hymns introduced by Ambrose in person, which they assumed must be the very same ones then used in the rite of his episcopal see. They therefore sent people to Milan to copy out the Ambrosian Office hymnal, and then incorporated it into their own proper Use of the Office, a change which brought them much unfavorable criticism. In the specific case of Optatus votis, they divided it into two parts, with the first four stanzas at Vespers and Matins, and the rest at Lauds. In the post-Tridentine period, however, the Cistercian Use was heavily romanized, and the hymn was replaced with the traditional Roman ones; a later reform restored “O grande cunctis” at Lauds, but not the first part at Vespers and Matins.
Here is a nice recording of the propers of the Mass of the Ascension from the Abbey of Triors in France.
