35 The Byzantine Empire

The Beginnings of the Byzantine Empire

The Byzantine Empire was the continuation of the Roman Empire in the Greek-speaking, eastern part of the Mediterranean. Christian in nature, it was perennially at war with the Muslims, Flourishing during the reign of the Macedonian emperors, its demise was the consequence of attacks by Seljuk Turks, Crusaders, and Ottoman Turks.

Byzantium was the name of a small, but important town at the Bosphorus, the strait which connects the Sea of Marmara and the Aegean to the Black Sea, and separates the continents of Europe and Asia. In Greek times the town was at the frontier between the Greek and the Persian world. In the fourth century BCE, Alexander the Great made both worlds part of his Hellenistic universe, and later Byzantium became a town of growing importance within the Roman Empire.

By the third century CE, the Romans had many thousands of miles of border to defend. Growing pressure caused a crisis, especially in the Danube/Balkan area, where the Goths violated the borders. In the East, the Sasanian Persians transgressed the frontiers along the Euphrates and Tigris. The emperor Constantine the Great (reign 306–337 CE) was one of the first to realize the impossibility of managing the empire’s problems from distant Rome. (86)

In 330 CE, Constantine decided to make Byzantium, which he had established a couple of years before and named after himself, his new residence. Constantinople lay halfway between the Balkan and the Euphrates, and not too far from the immense wealth and manpower of Asia Minor, the vital part of the empire.

“Byzantium” was to become the name for the East-Roman Empire. After the death of Constantine, in an attempt to overcome the growing military and administrative problem, the Roman Empire was divided into an eastern and a western part. The western part is considered as definitely finished by the year 476 CE, when its last ruler was dethroned and a military leader, Odoacer, took power. (86)

Byzantine Culture

Since the age of the great historian Edward Gibbon, the Byzantine Empire has a reputation of stagnation, great luxury and corruption. Most surely the emperors in Constantinople held an eastern court. That means court life was ruled by a very formal hierarchy. There were all kinds of political intrigues between factions. However, the image of a luxury-addicted, conspiring, decadent court with treacherous empresses and an inert state system is historically inaccurate. On the contrary: for its age, the Byzantine Empire was quite modern. Its tax system and administration were so efficient that the empire survived more than a thousand years.

The culture of Byzantium was rich and affluent, while science and technology also flourished. Very important for us, nowadays, was the Byzantine tradition of rhetoric and public debate. Philosophical and theological discourses were important in public life, even emperors taking part in them. The debates kept knowledge and admiration for the Greek philosophical and scientific heritage alive. Byzantine intellectuals quoted their classical predecessors with great respect, even though they had not been Christians. And although it was the Byzantine emperor Justinian who closed Plato’s famous Academy of Athens in 529 CE, the Byzantines are also responsible for much of the passing on of the Greek legacy to the Muslims, who later helped Europe to explore this knowledge again and so stood at the beginning of European Renaissance. (86)

Byzantine Religion

In the course of the fourth century, the Roman world became increasingly Christian, and the Byzantine Empire was certainly a Christian state. It was the first empire in the world to be founded not only on worldly power, but also on the authority of the Church. Paganism, however, stayed an important source of inspiration for many people during the first centuries of the Byzantine Empire.

When Christianity became organized, the Church was led by five patriarchs, who resided in Alexandria, Jerusalem, Antioch, Constantinople, and Rome. The Council of Chalcedon (451 CE) decided that the patriarch of Constantinople was to be the second in the ecclesiastical hierarchy. Only the pope in Rome was his superior. After the Great Schism of 1054 CE the eastern (Orthodox) church separated from the western (Roman Catholic) church. The center of influence of the orthodox churches later shifted to Moscow. (86)

Byzantine Iconography

Icon painting, as distinct from other forms of painting, emerged in the Early Byzantine period as an aid to religious devotion. In contrast, earlier Christian art had relied more on allegory and symbolism. For example, earlier art might have featured a lamb or a fish rather than Christ in human form. Before long, religious figures were being depicted in their human form to emphasize their humanity as well as their spirituality. While this issue would be debated and challenged during the later Iconoclastic period, for a time, images of the saints in icon paintings flourished.

After the adoption of Christianity as the only permissible Roman state religion under Theodosius I, Christian art began to change not only in quality and sophistication but also in nature. Paintings of martyrs and their feats began to appear, and early writers commented on their lifelike effect. Statues in the round were avoided as being too close to the principal artistic focus of pagan cult practices, as they have continued to be (with some small-scale exceptions) throughout the history of Eastern Christianity.

Icons were more religious than aesthetic in nature. They were understood to manifest the unique “presence” of the figure depicted by means of a “likeness” to that figure maintained through carefully maintained canons of representation. Therefore, very little room is made for artistic license. Almost every aspect of the subject matter has a symbolic aspect. Christ, the saints, and the angels all have halos. Angels, as well as some depictions of the Holy Trinity, have wings because they are messengers. Figures have consistent facial appearances, hold attributes personal to them, and use a few conventional poses.

Color plays an important role, as well. Gold represents the radiance of Heaven. Red signifies divine life, while blue is the color of human life. White is the Uncreated Light of God, only used for scenes depicting the resurrection and transfiguration of Christ. In icons of Jesus and Mary, Jesus wears a red undergarment with a blue outer garment (God as Human), and Mary wears a blue undergarment with a red outer garment (humanity granted divine gifts). Thus, the doctrine of deification is conveyed by icons. Most icons incorporate some calligraphic text naming the person or event depicted. Because letters also carry symbolic significance, writing is often presented in a stylized manner. (87)

Byzantine history goes from the founding of Constantinople as imperial residence on 11 May 330 CE until Tuesday 29 May 1453 CE, when the Ottoman sultan Memhet II conquered the city. Most times the history of the Empire is divided in three periods.

The first of these, from 330 till 867 CE, saw the creation and survival of a powerful empire. During the reign of Justinian (527–565 CE), a last attempt was made to reunite the whole Roman Empire under one ruler, the one in Constantinople. This plan largely succeeded: the wealthy provinces in Italy and Africa were reconquered, Libya was rejuvenated, and money bought sufficient diplomatic influence in the realms of the Frankish rulers in Gaul and the Visigothic dynasty in Spain. The rediscovered unity was celebrated with the construction of the church of Holy Wisdom, Hagia Sophia, in Constantinople. The price for the reunion, however, was high. Justinian had to pay off the Sasanian Persians, and had to deal with firm resistance, for instance in Italy.

Under Justinian, the lawyer Tribonian (500–547 CE) created the famous Corpus Iuris. The Code of Justinian, a compilation of all the imperial laws, was published in 529 CE; soon the Institutions (a handbook) and the Digests (fifty books of jurisprudence), were added. The project was completed with some additional laws, the Novellae. The achievement becomes even more impressive when we realize that Tribonian was temporarily relieved of his function during the Nika riots of 532 CE, which in the end weakened the position of patricians and senators in the government, and strengthened the position of the emperor and his wife. (86)

Justinian I devoted much of his reign (527–565 CE) to reconquering Italy, North Africa, and Spain. During his reign, he sought to revive the empire’s greatness and reconquer the lost western half of the historical Roman Empire. This attempt at restoration included an ambitious building program in Constantinople and elsewhere in the empire, by far the most substantial architectural achievement by one person in history.

One notable structure for which Justinian was responsible was the Hagia Sophia, or Church of Holy Wisdom, built by Isidorus of Miletus and Anthemius of Tralles, both of whom would oversee most building projects that Justinian ordered within Constantinople. (88)

The Hagia Sophia

Translated as “Holy Wisdom,” the Hagia Sophia was originally built and dedicated in the fourth century and served as the cathedral, or bishop’s seat, for Constantinople. From its dedication in 360 CE to the Nika Revolt of 532 CE, which proved to be the most violent week of rioting in city’s history, the Hagia Sophia was destroyed twice and rebuilt once, reflecting the symbolic power this religious structure held in its relation not only to Christianity but also to the city of Constantinople.

One of Justinian I’s first building campaigns following the Nika Revolt was to rebuild this cathedral. He turned to scholars Anthemius of Tralles and Isidorus of Miletus to design a revolutionary new church, one that adopted a central plan with extensions to the west and east by half dome apses. The dramatically raised, soaring central dome seems to magically float on light, creating a visually spectacular interior that originally had vibrant mosaic work.

Unfortunately, much of the original mosaic work has been destroyed.

Earthquakes in the sixth and ninth centuries, and the period of Byzantine Iconoclasm beginning around 726 CE, significantly damaged the structure and decoration of the Hagia Sophia. In its conversion to a mosque in 1453, when the Ottoman Empire overtook Constantinople, the religious work experienced more degradation, as mosque workers were known to sell individual mosaic tesserae as good luck charms for those who visited the space. (89)

Justinian’s Law

Byzantine Emperor Justinian I achieved lasting fame through his judicial reforms, particularly through the complete revision of all Roman law, something that had not previously been attempted. There existed three codices of imperial laws and other individual laws, many of which conflicted or were out of date. The total of Justinian’s legislature is known today as the Corpus juris civilis . It was not in general use during the Early Middle Ages. After the Early Middle Ages, interest in it revived. It was “received” or imitated as private law, and its public law content was quarried for arguments by both secular and ecclesiastical authorities. The revived Roman law, in turn, became the foundation of law in all civil law jurisdictions.

The provisions of the Corpus Juris Civilis also influenced the canon law of the Roman Catholic Church; it was said that ecclesia vivit lege romana — the church lives by Roman law. Its influence on common law legal systems has been much smaller, although some basic concepts from the Corpus have survived through Norman law — such as the contrast, especially in the Institutes, between “law” (statute) and custom. The Corpus continues to have a major influence on public international law. Its four parts thus constitute the foundation documents of the western legal tradition. (90)

Iconoclast Controversy

Around 726 CE, a period of iconoclasm brought the majority of Byzantine artistic production to a halt. Literally translated as “image breaking,” iconoclasm involved the destruction or desecration of religious imagery for the sake of preventing idolatry, as illustrated in a ninth-century drawing from the Chudlov Psalter. This moment was spurred by ongoing religious debate regarding the function and appropriateness of religious imagery. Those who argued against the use of images feared that worshipers would became too engrossed in the image itself, worshiping the image as an idol rather than focusing on the religious narrative or figures it represents. This controversial issue came to a head under Emperor Leo III, who prohibited the creation of new religious imagery and called for the removal and destruction of extant imagery. During this period, the only acceptable imagery to be included in church interiors was the cross. Following this iconoclastic outbreak, the Middle Byzantine Period (843–1204 CE) began when Empress Theodora reinstated the practice of venerating icons, thereby ushering in a new generation of artistic and architectural production.

The return of the splendor of Byzantine interior decoration can be seen in the Saint Mark’s Cathedral, Venice. Expanding the footprint of the Hagia Sophia to take on a Greek cross shape, Saint Mark’s Cathedral includes five monumental domes, each replete with golden mosaic work (on which work continued until the seventeenth century). While the imagery is no less lavish than earlier examples, imagery has been simplified (e.g., the removal of many superfluous details) since at this point, artists sought to emphasize the primacy of the religious narrative or figure being portrayed.

This is illustrated in a relatively contemporaneous version of Christ Pantocrator in the Church of the Dormition, Daphni, Greece (c. 1080–1100 CE). Located in the central dome of the church, this Christ Pantocrator looms large over worshipers. Holding the New Testament in his left arm and assuming a gesture of blessing with his right, Christ here assumes the traditional posture as Pantocrator, or “ruler of all,” a conventional representation of Christ that became popular during this era. (89)

The Collapse of the Byzantine Empire

After Justinian, contraction largely defines Byzantine history. The first onset of the Bubonic plague in Europe was one factor that contributed to a weakening of the Byzantine Empire in political and economic ways. As the disease spread throughout the Mediterranean world, the empire’s ability to resist its enemies weakened. By 568 CE, the Lombards successfully invaded northern Italy and defeated the small Byzantine garrison, leading to the fracturing of the Italian peninsula, which remained divided and split until re-unification in the 19 th century CE. In the Roman provinces of North Africa and the Near East, the empire was unable to stem the encroachment of Arabs. The decreased size, and the inability of the Byzantine army to resist outside forces, was largely due to its inability to recruit and train new volunteers due to the spread of illness and death. The decrease in the population not only impacted the military and the empire’s defenses, but the economic and administrative structures of the empire began to collapse or disappear.

Decay became inevitable after the Battle of Manzikert in 1071 CE after the Byzantine army was bested by the Seljuk Turks in combat. After the battle, the Byzantine Empire lost Antioch, Aleppo, and Manzikert, and within years, the whole of Asia Minor was overrun by the Seljuk Kingdom. The loss of territory and personnel left a power vacuum that western Europeans proved more than willing to fill. The Byzantine Emperor sent a request for help to pope Urban II, who responded by summoning the western world for the Crusades. The western warriors swore loyalty to the emperor, reconquered parts of Anatolia, but kept Antioch, Edessa, and the Holy Land for themselves. For more than half a century, the empire was ruled by monarchs from the West. The Byzantine Empire continued to lose territory, however, until finally the Ottoman Empire under Mehmet II conquered Constantinople in 1453 CE and took over government. (91)(86)
