Dies Irae

← Encyclopedia

The Dies Irae, “day of wrath,” is a Latin sequence on the Last Judgment — a rhymed poem of some fifty lines that became, for seven centuries, a fixed part of the Requiem Mass, the Catholic Mass for the dead. Its subject is the end of the world rendered as a single scene: the trumpet over the open graves, the dust that was a world rising to answer it, the dead standing, the written record brought forward — the liber scriptus in which everything done is set down, nothing omitted — and read out before the throne. The poem’s movement runs inward and downward, from that cosmic terror to a single frightened petition, Quid sum miser tunc dicturus? — what shall I, a wretch, say then, when even the just man is scarcely secure. The tone is not consolation but dread, and then a turn, late and quiet, toward mercy.

A poem of the thirteenth century

The poem dates from the middle of the thirteenth century and is most often attributed to Thomas of Celano, the Franciscan friar who also composed the earliest life of Francis of Assisi — the Vita Prima commissioned soon after Francis’s canonization in 1228 — along with a later legend of Clare. The attribution is traditional rather than secured by documentary proof. Scholarship treats the authorship as genuinely open: a rival ascription names the Dominican Latino Malabranca Orsini (d. 1294), lector at the Roman studium of Santa Sabina; older guesses reaching back to Gregory the Great, Bernard of Clairvaux, or Bonaventure have no purchase. What complicates any single name is that the sequence does not appear to be invented whole. Its imagery and several of its phrases — the dread of the dies illa, the plea Libera me, Domine — belong to an older responsory sung at the absolution over the dead, so the poem may be a versification and intensification of liturgical material already in the air rather than a wholly fresh composition. The Franciscan setting fits its temper. The thirteenth century, the century of Francis and of the friars who took the cross into the open air, was also the great age of the sermon on death and the four last things, and the Dies Irae reads like a preacher’s vision turned to verse: it does not argue, it shows.

What the poem does formally is part of its grip. It is written not in classical quantitative meter but in accentual trochaic dimeter — a hammering eight-syllable line, falling stress on stress — gathered into three-line stanzas that rhyme aaa, so that each unit closes on a triple chime before the next begins. The effect is incantatory and relentless, a drumbeat under the imagery. The opening sets the pattern at once:

Dies irae, dies illa, solvet saeclum in favilla

— the day of wrath, that day, will dissolve the age into ash. The Latin is plain to the point of starkness; the rhyme does the work that ornament would do elsewhere. After roughly seventeen such stanzas the meter breaks: the poem’s last lines abandon the triple rhyme and modulate into direct prayer — Pie Jesu Domine, dona eis requiem, merciful Lord Jesus, grant them rest — so that the structure itself enacts the turn from judgment to plea. The accusation of the liber scriptus gives way to Recordare, Jesu pie (remember, gentle Jesus, that I am the cause of your road), and the throne of terror is asked to remember the thief and the weeping Magdalen, to whom mercy was given.

Into the liturgy and the 1570 Missal

By the later Middle Ages the sequence had spread through the funeral liturgy of Latin Christendom, carried by the Franciscan and Dominican orders whose missions reached every parish. It belonged to a particular liturgical species. A sequence is a text — originally a trope, an expansion sung after the Alleluia of the Mass — and by the high Middle Ages thousands were in circulation, many of them local and ornamental. The reform of the Roman Missal under Pius V in 1570, the great post-Tridentine standardization that produced what later ages called the Tridentine Mass, swept nearly all of them away, retaining only four for the universal calendar — the Easter Victimae paschali, the Pentecost Veni Sancte Spiritus, the Corpus Christi Lauda Sion, and the Dies Irae for the dead. (A fifth, the Stabat Mater, was admitted in 1727.) The reduction left the Mass with two surviving doxological and angelic texts of an older stratum, the Gloria in excelsis Deo and the lesser doxology Gloria Patri, alongside its handful of retained sequences; against their tone of praise the Dies Irae stood as the one fixed text of fear. That ruling fixed the Dies Irae as the obligatory sequence of every Requiem in the Roman Rite and of the Mass of All Souls, where it had stood, by custom, since roughly the fourteenth century. Once embedded there, it became among the most quoted of all medieval Latin poems, its opening trochees a tag known far beyond anyone who could parse the rest.

The descending chant

What carried the Dies Irae furthest, however, was not the words but the melody welded to them. The plainchant is in the Dorian mode — a scale near to the minor, but without the raised seventh that pulls a modern tune toward resolution — and it opens with a stark, mostly stepwise descent, three notes falling and circling back, a shape that seems to sink under its own weight. Sung in a Requiem it is grave and processional; isolated, it is unmistakable. The chant entered the Liber Usualis, the great compendium of Catholic plainsong assembled by the monks of Solesmes whose nineteenth-century restoration of the chant — Guéranger’s refounded abbey, Pothier’s Liber Gradualis of 1883, Mocquereau’s paleography — fixed the melody in the form most performers know.

From the Renaissance onward composers wove the sequence into their settings of the Requiem, and three nineteenth-century settings in particular made the Dies Irae the dramatic center of the whole Mass for the dead. Mozart’s Requiem, left unfinished at his death in 1791, gives the sequence a driving, fearful chorus; Berlioz’s Grande Messe des morts of 1837 sets it against four brass choirs and a battery of timpani, the trumpet of the text become an actual trumpet wall; Verdi’s Requiem of 1874 returns to its Dies Irae movement again and again as a recurring terror, the loudest and most violent music Verdi ever wrote. None of these is liturgical in any ordinary sense — they are too vast for any altar — but all three take the medieval text at its word and stage the Judgment as overwhelming sound.

The melody also escaped the words entirely. Berlioz had already quoted the bare plainchant in the finale of his Symphonie fantastique of 1830 — the “Dream of a Witches’ Sabbath,” where the chant of the Church for the dead is handed to four bassoons and two tubas and turned, by tempo and orchestration, into a grotesque dance, the sacred melody profaned to summon a coven. From there the figure passed into the common vocabulary of European music as a token of death and the macabre: Liszt built a Totentanz on it, Saint-Saëns set it skeletal in the Danse macabre, Rachmaninoff returned to it across a career, Mahler folded it into the resurrection finale of his Second Symphony. By the twentieth century the first few notes had become musical shorthand, recognizable in concert works and later in film scores to listeners with no notion of the Liber Usualis or the Council of Trent — a falling phrase that means mortality before any word is sung.

Removal and survival

Within the Church the sequence’s standing changed sharply in the twentieth century. The reform of the Roman Missal that followed the Second Vatican Council, carried out across 1969 and 1970, removed the Dies Irae from the ordinary Requiem. The reasoning was deliberate. Annibale Bugnini, the architect of the reform, described the aim as clearing away texts that overstressed judgment, fear, and despair — what he called a negative spirituality inherited from the Middle Ages — in favor of a renewed accent on Christian hope and the resurrection of the body — the register, rather, of a text like the Compline antiphon Salve Regina, which pleads for mercy through the Mother rather than trembling before the Judge. The poem was not abolished but relocated: it survives in the reformed Liturgy of the Hours as an optional hymn, divided into sections, for the last weeks of the liturgical year and the Office of the Dead. It also remains in full liturgical use in the older Latin rite — the 1962 Missal celebrated as the extraordinary form — wherever a Requiem is sung according to the books Pius V fixed. And it endures, undiminished, in the concert hall, where the great settings are performed precisely for the terror the reformers wished to soften.

The four last things

The poem belongs to a wider medieval preoccupation with the novissima, the “last things” — usually enumerated as four: death, judgment, heaven, and hell. The scheme has a scriptural anchor in the Vulgate’s counsel to remember one’s last things in all that one does (Ecclesiasticus 7:40), and it was systematized in the Cistercian death-meditation of Bernard of Clairvaux and codified in the late Middle Ages — Denis the Carthusian’s De quattuor novissimis of the fifteenth century is the paradigm — into a pattern of contemplation that fed both the Ars Moriendi, the manuals on the art of dying, and the preaching that filled the churches. Within that frame the Dies Irae occupies the hinge between the second and the last: it stands at the moment of judgment and looks both ways, toward the death already suffered and toward the heaven or hell about to be assigned. The intervening state of purgatory, the cleansing fire that the Requiem’s prayers and suffrages were meant to shorten, is the very reason the Mass for the dead is offered at all — the living petitioning on behalf of souls not yet at rest. The sequence sits inside an entire architecture of eschatology, the doctrine of the end, the moment the apocalypse becomes personal: the general resurrection at the close of history is also, for each one summoned from the grave, a private accounting.

Sources and scholarship

The text and its problems are cataloged in the standard reference apparatus: the Library of Congress treats the poem as an anonymous medieval Latin work under its own authority heading, registering the disputed authorship rather than settling it. The case for and against the Celano attribution is laid out in the older but still-cited study by Donald E. Demaray, “Thomas of Celano and the Dies Irae”, The Asbury Seminarian, which surveys the medieval testimonies and the nineteenth-century debate over the poem’s origins. The peculiar liturgical history — how a genre of thousands of sequences was reduced by the Tridentine reform to a bare handful, the Dies Irae among the survivors — is traced in working detail by the church-music scholarship of Corpus Christi Watershed’s history of the sequences, which sets the 1570 ruling of Pius V in the context of the larger purge. The chant itself is preserved in the Solesmes Liber Usualis, whose restoration of the medieval melodies is the modern channel through which the descending Dorian phrase reaches performers and composers alike; the philological and editorial history of that restoration — Guéranger, Pothier, Mocquereau, the Vatican Graduale of 1908 — is the same scholarly enterprise that recovered the plainchant repertory as a whole. Among the larger literature in which the poem is read, J. M. Neale’s nineteenth-century work on medieval hymnody set the Dies Irae at the head of the tradition, and W. J. Irons’s English rendering of 1849, beginning “Day of wrath, O day of mourning,” became its best-known translation in the Anglophone hymnals.

The poem does not, in the end, close on the cosmos. Its last movement is a narrowing: from the trumpet over all the graves, to the assembled nations, to the single voice that has been speaking all along and now stops pleading for the world and begins pleading for itself. Oro supplex et acclinis — I pray, suppliant and bowed, my heart contrite as ash — gere curam mei finis: take care of my ending. The whole apparatus of wrath, the dissolving age, the opened book, the throne, contracts to one kneeling figure asking that its own last hour be held. That is where the sequence leaves the listener: not before the spectacle of the end of the world, but before the smaller and nearer fact that the reckoning read from the book will, line by line, be one’s own.
