Writing a Book on Used Books: An Interview with Eleonora Celora

This week, we’re looking back at one of our earlier episodes of “Meeting in the Middle Ages.” In 2022, we sat down with Eleonora Celora, a graduate student at the University of Notre Dame. We spoke to her about liturgical manuscripts as works of art, moving to France without knowing French, and creating a tool to help others understand medieval liturgical texts.

Eleonora’s journey to Notre Dame has taken her across the world. Moving from Italy to France and then to South Bend, Indiana, she is someone who jumps in feet first and overcomes challenges through determination and passion for her work. It was eye-opening to hear about her experiences shifting between languages and cultures. Being an international student is never easy—you are exposed to new foods, new ways of doing things, new social etiquette—but it can be really rewarding.

Ele’s experiences also provide unique insights into the strengths and weaknesses of the American PhD programme. During her undergraduate degree she developed an interest in music and manuscripts that led to her study the Middle Ages in more and more detail. But as she tells us, studying in Italy and the United States are two very different things. She has seen firsthand how different educational environments shape your research, subtly directing you to ask some questions and not others. For Ele, the solution has been to seek an international career as much as possible. In this increasingly interconnected, global academic world, we can all stand to benefit from collaborating with international researchers when we can. Working with scholars trained in other university systems can help us to see our fields in new ways and maybe ask the questions we’d never thought to ask.  

Thanks for listening. See you next time in the Middle Ages.

Liturgy in Service of Imperial Authority

As an integral part of the Church ritual, liturgical hymns provide what is possibly the most effective means of communicating dogmatic truths and conveying ethical ideals to the congregation. Combining words and music, hymns can produce a strong impression upon the minds of the faithful and play an important role in their spiritual edification. However, it would not be correct to assume that their content is exclusively spiritual. Rather, due to a specific relationship between the state and the church in the Eastern Roman Empire, better known as Byzantium (330-1453), it is not surprising that liturgical hymns contain many references to the emperor. In the aftermath of the legalisation of Christianity with the issuance of the Edict of Milan in 313 CE, and especially when Christianity became the official religion of the Roman Empire in 380 CE, the liturgy was regularly used to support imperial authority.

The promulgation of the Edict of Milan and the conversion of the emperor Constantine the Great (d. 337) to Christianity completely changed the position of the Church in the empire. After a period of persecutions, the Church became the second most important pillar of society, with the imperial power being the first. Especially important for the construction of this new reality was the production of the discourse surrounding Constantine’s conversion. This discourse was based on the cross, the supreme Christian symbol, and on several prominent Old Testament leaders of the chosen people, especially Moses, David, and later Joshua. The contribution of Eusebius (d. 339), sometimes characterised as “court theologian,” to the creation and dissemination of this discourse was enormous, and this laid the foundation for what would be later known as a ‘symphony’ or the harmonious coexistence of state and church.

The cross, initially understood as a symbol of Christ’s victory over the Devil and death, became closely related to the emperor and transformed into a symbol of imperial victories and prosperity of the empire with divine assistance after Constantine’s victory under that sign against Maxentius (Eusebius, VC 1.27-39).

The Vision of the Cross. Apostolic Palace, Vatican. Circle of Raphael (1520-1524).

This idea, after being developed in various literary genres, especially panegyrics, found its way into liturgical hymns. Hymnographers frequently eulogise the cross as a powerful weapon, which brings victories to the emperor and secures peace in the empire. Liturgical hymns for the Exaltation of the True Cross (14 September), the central annual feast of the cross in the Byzantine tradition, repeatedly stress not only the spiritual dimension of the cross in Christian life but also its military and triumphant functions. The best example is probably the apolytikion, as the main celebratory hymn for each feast is called, for the feast of the Exaltation: “O Lord, save your people and bless your inheritance, grant victory to the emperor against the barbarians, and guard your empire through your cross” (Festal Menaion, September 14). The hymn strongly emphasises the close interrelation between the cross, the empire and the church community. The community prays to God to save and protect the subjects of the empire through his cross, which secures imperial victories against the barbarian enemies (cf. Demacopoulos, 123). Similar references to the cross abound in hymns for this feast. However, for this occasion I will include only two more examples, both taken from an unpublished hymn attributed to Germanos I, Patriarch of Constantinople (d. 740), and preserved in an eleventh-century manuscript from the collection of Mount Sinai. The first one reads as follows:

“We pray, grant to the most pious emperor your power, through your life-giving cross, O Christ; he boasts about you and, placing his hopes in you, will be saved.”

Sinait. gr. 552, f. 129

In the second one, the invocation of the cross’s might is not phrased in generic terms; rather, the hymnographer makes specific references to the power of the cross against the Arab Muslims.

“Let us bow before the wood of the Cross, which provides the power to the most pious emperor against enemies, and subjects to him the foolish offspring of Hagar.”

Sinait. gr. 552, f. 128v

The cited example shows how a reference to the cross becomes part of inter-religious polemics. The author praises the cross as a source of power for the emperor to defeat his foes who are denoted as descendants of Hagar. The word “Hagarenes”, designating the offspring of Abraham’s slave Hagar in its biblical usage (Gen. 16; Chr. 5:19, and Ps. 82:7), was commonly employed by Christian authors to denote the Arabs both before and after the appearance of Islam, as they were believed to be the offshoot of Hagar’s son Ishmael.

In Byzantium, the emperor was also frequently related to distinguished Old Testament figures, especially to prominent leaders of the Israelites. Byzantine rhetorical treatises, such as the tenth-century On the Eight Parts of Rhetorical Speech, provide clear instructions to panegyrists to compare the emperor with Moses, David and Joshua the son of Nun. This practice gradually found its way to liturgical hymns. The aforementioned manuscript from the Mount Sinai collection transmits a hymn for the annual celebration of Joshua the son of Nun. Intriguingly, in the Christian tradition of the first millennium, Joshua was rarely regarded as a model warrior or related to the emperor. This perception changed from the ninth century onwards, especially at the time when Byzantine emperors attempted to recapture Palestine from the Arabs.

Joshua. Hosios Loukas Monastery, Greece, 11th c.

Having as the point of departure Joshua’s accomplishments and military exploits against the Amalekites, and especially the narrative that he led the Israelites into the Promised Land (Joshua 3:1-14), the author of the hymn from the Sinai manuscript puts Joshua’s leadership and military exploits in the foreground, directly associating him with the emperor.  Thus in one of the stanzas, the poet appeals to God as follows:

“You who were fellow-general of your servant Joshua against his opponents in the past, now in a similar way be fellow-general of the emperors against [their] enemies.”

Sinait. gr. 552, f. 11

There is little doubt that this and other references to Joshua need to be seen within the broader historical context of the Middle Byzantine period, especially in relation to the Byzantine-Arab wars during the reign of the emperors from the Macedonian dynasty (867-1056) who sought to return Palestine to Byzantine control. Joshua’s leadership skills and military prowess, which he demonstrated in warfare against the native population of the Promised Land, became a source of inspiration for Byzantine authors and artists during the same period. As a result, visual representations of Joshua appear with some frequency in monumental painting and on portable objects produced during the so-called Macedonian Renaissance.

Hymnographic texts, addressed to a wide audience, could also be effectively mobilised to reinforce imperial authority among imperial subjects. Even more so when a good opportunity was available, as in the present case, namely on the feast day of one of the most prominent leaders of God’s chosen people. Since the Byzantines regarded themselves as the New Israel, with the pious emperor as their leader comparable to the Old Testament leaders, the author of the kanon exploited this to relate the emperor to Joshua. In this respect, the hymn can be compared to other genres of Byzantine literature whose main purpose was to glorify the emperor.

Scenes from an Ivory Casket with Scenes of the Story of Joshua, The Metropolitan Museum of Art (10th c.).

As a conclusion, it can be said that the New Testament commandment to pray for those in power (1 Tim 2: 1-2) from the time of Constantine developed into the concept that the emperor is the chief protector of the church and orthodoxy and has to be glorified in liturgy. In addition, imperial success in wars against those of a different religion was understood as a guarantee for the freedom of the Christian faith in the empire. Moreover, by comparing the warfare between the Eastern Roman Empire and their enemies, particularly against the Persians and Arabs, with the wars that the biblical chosen people of ancient Israel waged against the Amalekites, Byzantine authors situated those wars within the biblical context attaching a sacred character to them. In that way, the Byzantines became the New Israel, and their emperors were understood as the successors of the Israelite leaders. Consequently, their inclusion in liturgical texts and the ritual was considered legitimate.

“To Hell or Heaven with the Greeks”: Common Apocalyptic Beliefs Between the Turks and the Greeks in the Late Middle Ages

        The expansion of the Oghuz Turks towards the Levant region in the early to mid- 11th century had crucial importance not only for the Middle eastern region but also world politics. The expansion of the Turkish political dominance in the region culminated in the Battle of Manzikert in 1071 which paved the way for various Turkish-speaking groups to migrate to Anatolia in the hopes of finding a new financial resource for their nomadic economic structure. The Turks conquereed to the region by the force of arms; however, as time passed, they began to adapt to the cultural, ecologic, politic and socio-economic realities of their new homelands. Their close interactions with the neighboring communities not only reshaped their physical appearances, economic structures, administrative and bureaucratic practices but also introduced them to new spiritual and religious beliefs. Contemporary scholarship in the area of interfaith and several cross-cultural studies have recently demonstrated how the Turks actually borrowed eschatological ideas and notions with respect to the end of the world and the developments that are expected to take place prior to this cataclysmic event.  

        Although interfaith and cultural exchange began taking place between the Greeks and Turks immediately after 1071 (and perhaps even before then), I would argue these interactions noticeably increased alongside the Turkish political expansion towards western Anatolia and Thrace especially after the late 1200s and early 1300s. The missionary activities of Turkish holy men and the tolerant attitudes of the state officials in these Turkish-controlled regions created an environment for Christians and Muslims to discuss various spiritual matters and learn more about each other’s faiths. In fact, one of the most influential Orthodox clerics, Gregory Palamas, was invited by the Ottoman court to converse about religion with a Muslim spiritual figure in the 1340s. Referring to several striking similarities between the Jesus Prayer and Dhikr practice, some scholars even argue that the influence of Islamic Sufi ideology encourages the appearance of Hesychasm in the Byzantine spiritual environment in this period.[1] Besides the Islamic ideological influence over Orthodox Christianity, it seems that some Christian beliefs also disseminated among the Muslim believers.

        A certain Ottoman Sufi by the name of Ahmed Bican who lived in fifteenth century Gallipoli seems to have possessed an extensive knowledge about the Byzantine apocalyptic traditions. In his book, Dürr-i Meknûn, not only he did refer to several Byzantine messianic beliefs, but he also refashioned them with an Islamized veneer. For example, although there is no certain date regarding the end of the world in the theology, adopting the Byzantine tradition, adopted the opinion that doomsday will take place in 1492. What is even more noteworthy is his familiarity with the Byzantine liturgical calendar. It seems that he was personally aware of the Byzantine system since he states that Byzantine scholars determined the era of humankind as 7000 years; however, since Muslims use a lunar calendar instead of solar calendar, he notes that it should be regarded as 7200 years by the Muslims. 

        Furthermore, a general belief about the blonde people in Byzantine apocalyptic and messianic expectations can be observed in Bican’s work too. According to these, the Byzantine peoples believed that their capital, the city of Constantinople, will fall to their enemies one day; however, a blonde nation from the northern regions will soon appear to help the Greeks to ‘liberate’ their previous possession, expelling the Muslims as far as Syria. In his work, Bican also stated that one of the “blonde peoples” from the northern regions will indeed recapture Constantinople and expel the Muslims soon but he also made some additions to the story. Attributing a messianic role to the Ottoman ruler, he argued that the sultan will appear in this desperate situation and be able to defeat the blonde people by recapturing Constantinople for the second time, glorifying the religion of Islam.

Georgios Klontzas, “The Last Judgement” (1540-1608).

         Yet lastly, Bican seems to have been aware of a Greek messianic tradition prophesizing “the return of the king” which promises a rightful ruler will reclaim the throne of Constantinople.  The Laskaris dynasty which came to power in Nicaea after 1204 had a special importance for western Anatolians since Laskarid rulers initiated an economic development program in the region and successfully protected the eastern borders against the Turcoman incursions in this period. When Michael Palaeologus usurped the Byzantine throne in 1261 by imprisoning and then blinding John, the last Laskarid ruler of the empire, the western Anatolian Byzantines began developing stories, predicting his expected return. Cyril Mango argues this belief even spread to the European half of the empire since a prophecy which was circulated in the 13th century tells about a civil war that would take place in Constantinople. According to this prophecy, he argues, at the end of the civil war, as an old and shabbily dressed man, John Laskaris would appear in Constantinople to be crowned by the angels. His shabbily dress and his old age refers to the imprisonment case and signals that a civil war will take place in his later years. After the enthronement, the angels will give him a sword, saying; “Take courage, John, vanquish the enemy!”

        In Bican’s work, I think, it is possible to observe several clues about this late Byzantine apocalyptic expectation since Bican also talks about a civil war that would wake place in Constantinople. According to his interpretation, the fighting parties will be led by two military figures who have these initials in their name: “M” and “S”. Although, I think, “M” might represent Michael Palaeologus, “S” does not match with John’s initial. However, I argue that this letter might be modified in a later period due to Bican’s concern with adjusting it to a specific contemporary ruler. It is also within the boundaries of possibility that “S” stands for the second and last consonants of the dynastic name of John: Laskaris. Although the events were given in a very fragmented nature in this work, Bican also points out an imprisonment case, saying that the imprisoned will soon take the throne by defeating his enemy which has a clear resemblance with John Laskaris’ imprisonment by Michael.

        Messianic and apocalyptical intellectual exchange constitute a small part of interactions between the various groups of Christians and Muslims, who have lived in the Middle East and the Balkans side by side for the centuries. There are many more cultural and religious interactions between these people in this regard including but not limited to spread of brotherhood (futuwwa) institutions from the crusader states to the Muslim world in the Levant region. Although scholars have begun turning their focus to these borrowings in the eastern Mediterranean in the last couple of decades, there are still a long way to traverse since western Anatolia and the Balkans have received less attention so far. Hopefully, as the winds of time are changing, more scholars and students will become curious about the relations, interactions and shared traditions between Christians and Muslims in Istanbul and beyond.
