Pope Donus (676-678)

A tiny pontificate, but in the right place

Donus reigns between Adeodatus II and Agatho. This chronological position explains almost all of his importance. Adeodatus II had maintained the anti-Monothelite line without achieving the final settlement. Agatho, for his part, would preside over the Roman synod of 680 and send to Constantinople the profession of faith that would enable the ecumenical council to condemn Monothelitism.^[9][10]

Donus is not the pope of the definition. He is the pope immediately before the definition. Treccani recalls that, when he begins his pontificate, the Typos (imperial edict promulgated in 648 by Constans II) is still in force: this text had withdrawn the Ecthesis (the profession of faith imposed in 638 which had provoked the religious conflict), but still forbade public discussion of the problem of Christ's energies and wills.^[11]

The nuance is crucial. Rome does not yet live in dogmatic peace. The previous popes had refused the ambiguous synodical letters of Constantinople — synodical letters being the official letters by which a newly elected patriarch sets out his faith to Rome — and the memory of the arrest of Martin I remains recent. Donus reigns in this intermediate zone: the frontal rupture eases, but doctrinal truth has not yet been defined in council.

The pope of three Roman dossiers

The ancient sources retain above all three dossiers: the reordering of the Boetianum monastery, the return of Ravenna to Roman obedience, and several works in churches of Rome or its ancient roads.^[12][13][14]

These three dossiers seem modest only if one looks for a spectacular great event. In reality, they touch three nerves of the 7th-century Church: purity of faith in a Rome filled with Eastern refugees; the jurisdiction of Peter facing a Church of Ravenna backed by the Empire; the material continuity of apostolic memory in a poor, threatened, Byzantine city.

The pope the emperor seeks too late

The last element is almost ironic. Constantine IV wants to bring the Empire out of the Monothelite deadlock. According to Treccani, the emperor pushes the Patriarch of Constantinople to send not a dogmatic synodical letter, but a letter of exhortation; then in August 678 he addresses a divalis iussio — an official and solemn letter from the emperor — inviting the pope to send delegates to discuss with the patriarchs of Constantinople and Antioch.^[15]

But Donus is already dead. The request therefore arrives under Agatho. This article must not attribute to Donus what Agatho will accomplish; it must rather show that Donus is the pope to whom the first imperial gesture of pacification was destined, even though the Roman answer will be given by his successor.

Table of witnesses

The Holy See: dates and identity

The Vatican's official entry gives Donus as 78th pope, with the pontificate beginning on 2 November 676, ending on 11 April 678, and birth in Rome.^[16] These three facts suffice to fix the canonical title of the article: Pope Donus (676-678).

The Liber Pontificalis gives a duration of one year, five months and ten days, which matches the interval between 2 November 676 and 11 April 678 well. It adds that the vacancy after his death lasted two months and fifteen days.^[17]

The Liber Pontificalis: a short but dense notice

The Roman notice begins soberly: Donus is Roman, son of Mauricius. It gives neither his date of birth, nor his earlier career, nor his age.^[18] Modern reconstructions must therefore remain cautious.

The same notice then lists his acts: paving of the upper quadriporticus of St Peter's with large marbles; restoration of the church of the Apostles on the Ostian Way; dedication of St Euphemia on the Appian Way; enlargement of the honours of the clergy; discovery of Syrian Nestorian monks in the Boetianum; return of Ravenna; appearance of a star for three months; ordinations; burial at St Peter's.^{[19][20][21][22][23]}

"In his time, the Church of Ravenna, which had separated itself from the Roman Church on account of autocephaly, submitted itself anew to its former apostolic See." — Liber Pontificalis, notice on Donus (English translation)^[24]

Treccani: the critical key to the pontificate

Stefano Gasparri's notice for Treccani gives the best overall reading. It places Donus at a moment when two factors push Rome and Constantinople to resume contact: on the one hand, the Islamic conquest has reduced the political weight of the Eastern patriarchates where the Monophysite and Monothelite crisis had taken root; on the other hand, Byzantine Italy is weakened by the Lombards, notably after Rothari and Grimoald.^[25]

Treccani also links the Ravenna dossier to imperial policy. The weakening of imperial support for Ravennate autocephaly makes Ravenna's gradual return toward Rome possible. But the notice warns against too simple a reading: the Roman Liber Pontificalis and Agnellus of Ravenna do not tell the affair in the same way.^[26]

Roman, son of Mauricius

All that the principal source says of Donus before his election fits in one formula: "Donus, natione Romanus, ex patre Mauricio".^[27] He is therefore Roman, and his father's name is Mauricius. The rest is silence.

This silence is not exceptional. The 7th-century pontifical biographies recount above all the bishop of Rome in the exercise of his office. They almost never provide a childhood, an education or a full career, except when an earlier fact becomes necessary to understand the pontificate.

A name not to be confused

The Latin sources give Donus; modern forms vary: Dono in Italian, Domnus or Donnus in some notices.^[28] This variation also explains the later confusion with a supposed "Donus II": a second pope of this name, recorded as "Domnus" (mention "domnus de Suri") in almost all catalogues (three excepted) between Benedict VI and Benedict VII, never existed — modern scholarship sees in it a misreading of the mention "domnus de Suri" designating Benedict VII, bishop of Sutri.^[29] This apocryphal figure does not concern the historical pope of 676-678, but it shows why the precise title Pope Donus (676-678) is preferable to a simple "Donus".

The election after Adeodatus II

Adeodatus II dies on 16 June 676 according to the Vatican entry.^[30] Donus is consecrated on the following 2 November. New Advent speaks of an interval of four months and seventeen days; the Liber Pontificalis in Adeodatus's notice gives four months and fifteen days for the vacancy, which reflects slight variations in calculation or tradition.^[31][32]

The length of this vacancy recalls a constraint peculiar to Byzantine Rome: the papal election must still reckon with imperial or exarchal confirmation. Donus is not elected in a papacy temporally independent and sovereign; he governs a Roman Church still embedded in imperial Italy.

The Monothelite controversy is not yet closed

Monothelitism maintained, in various formulations, that Christ would have only one will. The Catholic faith would on the contrary confess at Constantinople III that the incarnate Word possesses two natural wills and two natural operations, divine and human, without division of person and without sinful opposition.^[33]

At the moment Donus becomes pope, this definition does not yet exist. The Typos of 648 still forbids discussion of the question of the wills and operations. After Martin I, Eugene I, Vitalian and Adeodatus II, Rome has learned to refuse ambiguous formulas without each time provoking a political rupture impossible to sustain.^[34]

This prudence does not mean doctrinal compromise. It means that Rome holds the faith within an unstable imperial framework. Donus belongs to this line: he produces no great preserved doctrinal act, but his pontificate belongs to the continuity that will enable Agatho to speak with force in 680.

An Eastern Mediterranean transformed by Islamic expansion

Treccani insists on a background fact: of the five ancient Christian patriarchal sees, only those of Rome and Constantinople are still found within the Empire's borders, the others — Alexandria, Antioch and Jerusalem — having been submerged by Islamic expansion.^[35]

This transformation changes imperial religious policy. Monothelitism had been conceived as an attempt at reconciliation with Eastern Monophysite circles. But the Arab conquests have shifted the balance of power. The Empire needs a solid peace between Rome and Constantinople more than an ambiguous doctrinal formula that has become politically less useful.

Italy under Lombard pressure

The second factor is Italian. The Lombards, with King Rothari (636-652), had vigorously resumed the offensive, wresting substantial territories from Byzantium; then Grimoald, duke of Benevento turned king of the Lombards (662-671), attached Benevento to his power.^[36]

Rome is therefore not a tranquil capital. It still depends on the Byzantine framework for its security, while defending against Constantinople a doctrinal truth that the Empire long sought to neutralize. Donus's pontificate is understood within this tension: Roman fidelity, the Empire's political need, Lombard pressure, Mediterranean recomposition.

What the Liber Pontificalis reports

The most striking dossier in the notice is that of the Boetianum monastery — a Roman monastery whose name the Latin notice writes Boetiana, perhaps in connection with the great Roman family of the Boethii. The Liber Pontificalis states that Donus discovered Syrian Nestorian monks there; he dispersed them among various monasteries and placed Roman monks in their establishment.^[37]

New Advent takes up this information, speaking of a colony of Syrian Nestorian monks at Rome.^[38] Britannica summarizes it likewise: Donus is said to have dispersed the Monasterium Boetianum, a monastery of Nestorian Syrians.^[39]

Why Syrians in Rome?

The fact is not isolated. The 7th century sees Eastern Christians arriving in Italy — monks, clerics, refugees or scholars — driven by conquests, imperial crises and doctrinal controversies. Treccani stresses that Rome then receives many refugees from regions occupied by the Muslims, and that the long wave of Eastern heresies still touches the city.^[40]

The term "Nestorian" must be understood in the Latin ecclesiastical vocabulary of the time: it designates a Christology judged incompatible with the personal unity of Christ confessed at Ephesus and Chalcedon. The article need not reconstruct the exact doctrine of these monks, which the sources do not detail; the solid fact is that Rome identifies them as heretics and places them under control.

A correction with no account of violence

Donus's measure is firm, but the source speaks neither of a bloody trial, nor of expulsion from Rome, nor of physical persecution. He disperses the monks among various monasteries and installs Roman monks at the Boetianum.^[41]

This detail deserves notice. The aim seems twofold: to prevent a coherent heretical community from continuing to exist as an autonomous centre; to place its members in monastic settings where they can be supervised, corrected or absorbed; and to take back the establishment itself for a Roman community.

A Christological issue consistent with the century

The Boetianum is not an isolated anecdote. The Monothelite crisis also concerns Christology. 7th-century Rome is obsessed with one fundamental question: how to confess Christ as true God and true man, without dividing his person and without diminishing his humanity?

Nestorianism is perceived as an excessive separation; Monothelitism as a reduction of Christ's human will. Between the two, Rome keeps the Catholic balance: one single divine person, two natures, and soon two natural wills. Donus does not write this synthesis, but his action against the Boetianum belongs to the same horizon of Christological fidelity.

The schism of Maurus

Ravenna is no ordinary Italian city. Former Western imperial capital, seat of the Byzantine exarch, it carries considerable political weight. In the 7th century, its archbishop Maurus obtains from Constans II a privilege of autocephaly: Ravenna claims no longer to depend juridically on Rome.^[42]

This situation directly wounds Roman jurisdiction. It is not merely administrative: if a great imperial Church of Italy can free itself from the Apostolic See under political patronage, the balance between Rome, Ravenna and Constantinople changes profoundly.

The Roman account: Reparatus returns

The Liber Pontificalis states that in Donus's time the Church of Ravenna, separated from Rome on account of autocephaly, submitted itself anew to its former apostolic See. It adds that Archbishop Reparatus died immediately afterwards, "as it pleased God".^[43]

New Advent makes it one of the great facts of the pontificate: Reparatus, successor of Maurus, returns to the obedience of the Holy See, ending the schism provoked by the attempt at autocephaly.^[44]

Treccani's critique: a more complex exit from crisis

Treccani strongly qualifies this account. Agnellus of Ravenna states that Reparatus was consecrated by three of his suffragans according to Ravennate usage, which seems to contradict the idea of an immediate and complete return to Rome.^[45]

But the contradiction is not absolute. Treccani notes that Agnellus also reports a decree of Reparatus limiting to eight days the stay in Rome of a Ravennate elect come for his consecration. Such a rule makes sense only if one admits at least a de facto abandonment of autocephaly.^[46]

The best summary is therefore cautious: under Donus, Ravenna's claim to autocephaly begins to recede or is already practically abandoned, but its concrete liquidation remains difficult and will only be completed in the following years.

What recent studies add

Modern studies on Ravenna confirm that neither the Roman nor the Ravennate sources are entirely neutral. The 666 privilege, attributed to Constans II, is famous but short-lived; the details of its revocation or abandonment remain opaque.^[47]

After the Arab war, Constantine IV seeks ecclesial peace: he writes to Donus, then, Donus being dead, the dossier passes to Agatho. The Liber Pontificalis notes under Agatho that Archbishop Theodore of Ravenna, successor of Reparatus, presented himself of his own accord to the Apostolic See; Treccani concludes that with this same Theodore the crisis was surely resolved, even though after-effects poisoned relations between Rome and Ravenna for a long time afterwards.^[48]

Donus thus stands at the beginning of the repair. He does not settle everything, but his pontificate marks a clear shift: Ravenna is no longer supported by the Empire against Rome in the same way.

St Peter's: the quadriporticus paved with marble

The Liber Pontificalis states that Donus paved with large marbles the upper atrium of the blessed apostle Peter, before the church, in the quadriporticus.^[49]

Treccani specifies that this open-air atrium, within the quadriporticus of St Peter's, was called the paradisum. The large marble slabs almost certainly came from some ancient monument, and the work probably lasted until the 12th century, before a new paving.^[50]

The gesture is more than embellishment. In an impoverished Rome, the visible centre of Petrine memory is maintained by recovery, adaptation and continuity. The stones of the ancient city serve at the threshold of the Apostle's basilica.

The church of the Apostles on the Ostian Way

The Roman notice also says that Donus restored and dedicated the church of the Apostles situated on the Ostian Way.^[51] New Advent adds an important qualification: it may be not St Paul Outside the Walls itself but, following a conjecture of Duchesne, a small church on the road to St Paul's marking the place where St Peter and St Paul are said to have parted on their way to martyrdom.^[52]

This caution avoids a frequent error. The expression "ecclesiam Apostolorum sita via Ostiense" is not enough to identify St Paul Outside the Walls automatically. The tradition of the place where the two apostles parted better explains the dedication to the "Apostles".

St Euphemia on the Appian Way

The Liber Pontificalis adds that Donus likewise dedicated the church of St Euphemia on the Appian Way.^[53] Treccani locates this sanctuary outside the city, near Albano, and notes that the name survived later in that of a farm estate called S. Funia.^[54]

St Euphemia is not a neutral name in doctrinal history. The basilica of Chalcedon dedicated to St Euphemia was the venue of the 451 council, which confessed Christ in two natures. Even though the source does not say Donus had this memory in mind, the name resonates strongly in an age dominated by Christological quarrels.

The Roman clergy honoured

The notice finally adds that Donus "amplified" the honours of the clergy in its various orders.^[55] The formula is brief and does not allow a precise reform to be reconstructed. It nevertheless indicates attention to the Roman ecclesiastical body: priests, deacons, other orders, liturgical and administrative service.

Among the neighbouring popes, this same concern is often seen: distributions, ordinations, restoration of basilicas, organization of monasteries. 7th-century pontifical Rome holds together through these concrete gestures as much as through great doctrinal letters.

The three-month star

The Liber Pontificalis reports that in the month of August, while Donus was pope-elect, a star appeared on the Eastern side, from cockcrow until morning, for three months, and that its ray seemed to pierce the heavens.^[56]

The source adds that all provinces and nations marvelled at this sight, then that the star disappeared after returning upon itself. It then connects this sign with a great mortality come from the East.^[57]

How should this passage be read?

The article must neither mock this account, nor turn it into precise astronomical proof without investigation. The notices of the Liber Pontificalis often connect celestial events, calamities and pontificates. The text preserves a religious memory of the world: natural phenomena are read as signs, warnings or historical markers.

It may however be noted that the eastern orientation of the phenomenon and the mention of a mortality come from the East belong to a very concrete 7th-century imagination: the Eastern Mediterranean brings Rome refugees, controversies, imperial news, diseases, wars and signs. The account therefore also expresses the impression of a Roman world shaken by upheavals come from the East.

What must not be deduced from it

Historical caution is required. The Liber Pontificalis gives neither a precise astronomical date, nor a sufficiently technical description to identify a modern comet with certainty. It reports a celestial apparition in the language of its time. The article must therefore cite the fact as the source's narrative tradition, without pretending to possess a certain scientific identification.

The imperial initiative

At the end of Donus's pontificate or just after his death, Constantine IV understands that the Empire's religious unity requires a solution. Treccani reports that he puts pressure on Patriarch Theodore of Constantinople to write to the pope not a synodical letter, but a letter of exhortation.^[58]

Then, in August 678, the emperor addresses a divalis iussio to Donus. He invites Rome to send three legates of the Roman Church, twelve bishops of the dioceses subject to Rome and four heads of the Greek monasteries of Rome, in order to discuss with the patriarchs of Constantinople and Antioch. He promises a naval escort and absolute neutrality.^[59]

This last detail is essential. After the arrest and exile of Martin I, Rome had concrete reasons to fear imperial conferences. The promise of neutrality indicates that Constantine IV wants to signal a break with past violence.

The letter arrives after Donus's death

The imperial request arrives too late for Donus. Treccani specifies that the divalis iussio reaches Rome when his body has already been buried at St Peter's on 11 April 678.^[60]

EWTN summarizes the relay: to end the Monothelite controversy, Constantine IV asks Donus in 678 to send twelve bishops and four superiors of Western Greek monasteries; Agatho, having become pope in the meantime, then organizes the consultation of the West.^[61]

From Donus to Agatho

The continuity is clear. Donus is the initial addressee of the imperial gesture; Agatho will be its Roman executor. Around Easter 680, Agatho presides over a Roman synod of 125 bishops, then his legates bring to Constantinople the profession of faith condemning Monothelitism.^[62]

Donus's pontificate thus becomes an invisible threshold. It does not produce the dogmatic letter, but it stands at the moment when the Empire stops seeking only compromises and begins to accept that a true doctrinal decision is necessary.

"To put an end to the Monothelite controversy, Emperor Constantine IV asked Pope Donus in 678 to send twelve bishops and four superiors of Western Greek monasteries." — Introduction to the acts of Constantinople III, EWTN^[63]

The fidelity of short pontificates

Donus is not a famous pope. He founds no school, promulgates no great document, presides over no ecumenical council. But the history of the Church is not made only of visible summits. It is also made of pontificates that maintain order, correct a local heresy, repair sanctuaries, defend a wounded jurisdiction and hand the situation on to the one who will be able to act further.

In the 7th-century series, this fidelity matters. Without Martin I, Roman faith might have yielded under violence. Without Vitalian, Rome might have remained isolated. Without Adeodatus II, the anti-Monothelite line might have been lost in too vague a détente. Without Donus, the transition toward Agatho would have lacked a moment of Roman stabilization.

Keeping the faith in details

The Boetianum shows that doctrinal fidelity is sometimes played out in a discreet monastery. Ravenna shows that a question of jurisdiction can carry a deeper truth about the Apostolic See. The restorations of St Peter's and the Roman roads show that the material memory of the faith also counts: holy places form the people as much as texts do.

Donus thus recalls a simple law: the Church advances through great definitions, but also through guardians of thresholds. He is the pope who precedes Agatho. That suffices to give him a place: he holds Rome until the moment when Rome can speak to the council.

• Pope Adeodatus II — immediate predecessor, last pontificate before Donus.
• Pope Saint Agatho — successor of Donus, pope of the Roman synod preparing Constantinople III.
• Council of Constantinople III (680-681) — definition of Christ's two natural wills and two natural operations.
• Pope Saint Martin I — martyr of Roman resistance to the imperial Typos.
• Pope Saint Vitalian — pope of the prudent détente with Constantinople and of the Ravennate dossier.
• The Old Basilica of St Peter — architectural context of the quadriporticus restored by Donus.
