Missa Papae Marcelli, or Pope Marcellus Mass, is a mass sine nomine by Giovanni Pierluigi da Palestrina. It is his best-known mass,[1] [2] and is regarded as an archetypal example of the complex polyphony championed by Palestrina. It was sung at the papal coronation Masses (the last being the coronation of Paul VI in 1963).
The Missa Papae Marcelli consists, like most Renaissance masses, of a Kyrie, Gloria, Credo, Sanctus/Benedictus, and Agnus Dei, though the third part of the Agnus Dei is a separate movement (designated "Agnus II").[3] The mass is freely composed, not based upon a cantus firmus, paraphrase, or parody. Perhaps because of this, the mass is not as thematically consistent as Palestrina's masses based on models.[4] It is primarily a six-voice mass, but voice combinations are varied throughout the piece; Palestrina scores Agnus II for seven voices, and the use of the full forces is reserved for specific climactic portions in the text. It is set primarily in a homorhythmic, declamatory style, with little overlapping of text and a general preference for block chords such that the text can clearly be heard in performance, unlike many polyphonic masses of the 16th century. As in much of Palestrina's contrapuntal work, voices move primarily in stepwise motion, and the voice leading strictly follows the rules of the diatonic modes codified by theorist Gioseffo Zarlino.[5]
The mass was composed in honor of Pope Marcellus II, who reigned for three weeks in 1555. Recent scholarship suggests the most likely date of composition is 1562, when it was copied into a manuscript at the Basilica di Santa Maria Maggiore in Rome.[4]
The third and closing sessions of the Council of Trent were held in 1562–63, at which the use of polyphonic music in the Catholic Church was discussed. Concerns were raised over two problems: first, the use of music that was objectionable, such as secular songs provided with religious lyrics (contrafacta) or masses based on songs with lyrics about drinking or lovemaking; and second, whether imitation in polyphonic music obscured the words of the mass, interfering with the listener's devotion. Some debate occurred over whether polyphony should be banned outright in worship, and some of the auxiliary publications by attendants of the Council caution against both of these problems. However, none of the official proclamations from the Council mentions polyphonic music, excepting one injunction against the use of music that is, in the words of the Council, "lascivious or impure".[6]
Starting in the late 16th century, a legend began that the second of these points, the threat that polyphony might have been banned by the Council because of the unintelligibility of the words, was the impetus behind Palestrina's composition of this mass. It was believed that the simple, declamatory style of Missa Papae Marcelli convinced Cardinal Carlo Borromeo, on hearing, that polyphony could be intelligible, and that music such as Palestrina's was all too beautiful to ban from the Church. In 1607, the composer Agostino Agazzari wrote:
