Byzantine mosaics


Byzantine mosaics are mosaics produced from the 4th to 15th centuries in and under the influence of the Byzantine Empire. Mosaics were some of the most popular and historically significant art forms produced in the empire, and they are still studied extensively by art historians. Although Byzantine mosaics evolved out of earlier Hellenistic and Roman practices and styles, craftspeople within the Byzantine Empire made important technical advances and developed mosaic art into a unique and powerful form of personal and religious expression that exerted significant influence on Islamic art produced in Umayyad and Abbasid Caliphates and the Ottoman Empire. In addition, Byzantine mosaics went on to influence artists in the Norman Kingdom of Sicily, in the Republic of Venice, and, carried by the spread of Orthodox Christianity, in Bulgaria, Serbia, Romania and Russia. In the modern era, artists across the world have drawn inspiration from their focus on simplicity and symbolism, as well as their beauty.

Historical context

The byzantine mosaic art originated in the Greek tradition of road-building, since Greek roads were often made using small pebbles organized into patterns. By the Hellenistic Period, floor and wall art made of natural pebbles was common in both domestic and public spaces. Later, as the Roman Empire expanded and became the dominant cultural force in the Mediterranean and Near East, Roman artists were heavily influenced by the Greek art they encountered and began installing mosaics in public buildings and private homes throughout the empire. They also added small clay or glass pieces called tesserae, a material that were also being in use during the hellenistic period creating more colorful and finely-detailed images.

In 330CE, the emperor Constantine moved the empire's capital from Rome to Byzantium, renaming it Constantinople after himself. Historians generally use this date for the beginning of the Byzantine Empire and divide Byzantine art into three historical periods: early, middle and late.

The early period

Constantine's conversion to Christianity lead to extensive building of Christian basilicas in the late 4th century, in which floor, wall, and ceiling mosaics were adopted for Christian uses. The earliest examples of Christian basilicas have not survived, but the mosaics of Santa Constanza and Santa Pudenziana, both from the 4th century, still exist. In another great Constantinian basilica, the Church of the Nativity in Bethlehem, the original mosaic floor with typical Roman geometric motifs is partially preserved.
The reign of Justinian I in the 6th century coincided with the first golden age of the Byzantine Empire. In 537, he completed the construction of a new patriarchal cathedral in the capital city of Constantinople that would be the global center of the Orthodox Church: the Hagia Sofia. At the time, it was the world's largest building and considered the epitome of Byzantine architecture. The cathedral was decorated throughout with what were undoubtedly some of the most incredible figurative mosaics of this time period, but unfortunately these were all destroyed during the Iconoclasms that followed. The oldest mosaics that exist today in the Hagia Sofia date from the 10th through the 12th centuries, not this earlier period.
After Rome was sacked, Ravenna became the capital of the Western Roman Empire from 402 until 476, when the empire collapsed after being conquered by Theodoric the Great and the Ostrogoths. While Ravenna was under Gothic control, Arian patrons had embarked upon a notable building program of chapels and baptisteries in Ravenna. In 535, the city was conquered by Justinian I, who created the Exarchate of Ravenna, effectively making Ravenna the seat of Byzantine power on the Italian Peninsula. Orthodox bishops under Justinian continued and expanded the construction of basilicas to the adjacent port city of Classe, commissioning some of the finest mosaics anywhere in the world. Surviving monuments, some of which predate Exarchate, include the Basilica of San Vitale, the Archiepiscopal Chapel, the Arian Baptistry, the Neonian Baptistry, the Mausoleum of Galla Placidia, the Basilica Sant’Apollinare Nuovo, the Mausoleum of Theodoric and the Basilica of Sant'Apollinare in Classe. All eight of these monuments have been inscribed on the UNESCO World Heritage list as superb examples of early Christian mosaic art.
, Greece, which are some of the earliest remaining examples of early Christian mosaic art
Although it might be the most famous, Ravenna is by no means the only place where early Byzantine Mosaics are well-preserved today. The city of Thessaloniki in Greece was the second most important city in the empire in terms of both wealth and size, and like Ravenna its early Christian monuments have been designated UNESCO World Heritage sites. Masterpieces of early mosaic art in Thessaloniki include the Church of Hosios David, the Hagios Demetrios, and the Rotunda.
In addition, archeological discoveries in the 19th and 20th centuries unearthed many Early Byzantine mosaics in the Middle East, including the Madaba Map in Jordan as well as other examples in Egypt, Lebanon, Syria, Israel, and Palestine.

The Iconoclasm

The events that mark the division between early and middle Byzantine art are called the Iconoclastic Controversies, which took place from 726–842. This period is defined by a deep skepticism towards icons; in fact, Emperor Leo III placed an outright ban on the creation of religious images, and authorities within the Orthodox Church encouraged the widespread destruction of religious art, including mosaics. As a result, the iconoclastic period drastically reduced the number of surviving examples of Byzantine art from the early period, especially large religious mosaics.

Middle and late Byzantine mosaics

Following the Iconoclasm, Byzantine artists were able to resume creating religious images, which people accepted not as idols to be worshiped, but as symbolic and ceremonial elements of religious ritual spaces. The first part of this period, from 867–1056, is sometimes called the Macedonian Renaissance and is seen as the second golden age of the Byzantine Empire. Churches throughout the empire, and especially the Hagia Sophia in Constantinople, were redecorated with some of the finest examples of Byzantine art ever created. For instance, the monasteries at Hosios Loukas, Daphni, and Nea Moni of Chios have all been recognized as UNESCO World Heritage Sites, and they contain some of the most magnificent Byzantine mosaics from this period.
, Venice, Italy
Until the disastrous sack of Constantinople in 1204 at the hands of the Fourth Crusader Army, Byzantium was seen by many in Europe as the last light of civilization due to its inherited legacy of Rome and continued cultural sophistication. So during the 10th and 11th centuries, even states that were at odds with the Byzantine Empire imitated Byzantine style and sought out Greek artists to create religious mosaic cycles. For instance, the Norman King Roger II of Sicily was actively hostile to Byzantium, but he imported Greek craftspeople to create the mosaics for Cefalù Cathedral. Similarly, the earliest surviving mosaics in St. Mark's Basilica in Venice were probably created by artists who had left Constantinople in the mid-11th century and also worked at Torcello Cathedral.

Techniques

Like other mosaics, Byzantine mosaics are made of small pieces of glass, stone, ceramic, or other material called tesserae. During the Byzantine period, craftsmen expanded the materials that could be turned into tesserae, beginning to include gold leaf and precious stones, and perfected their construction. Before the tesserae could be laid, a careful foundation was prepared with multiple layers, the last of which was a fine mix of crushed lime and brick powder. On this moist surface, artists drew images and used tools like strings, compasses, and calipers to outline geometric shapes before the tesserae were carefully cemented into position to create the final image.

Aesthetics

In Byzantine religious art, unlike the Classical Greek and Roman art that preceded it, symbolism became more important than realism. Instead of concentrating on making the most realistic images possible, mosaic artists of this time wanted to create idealized and sometimes exaggerated images of what existed inside the soul of a person. In addition, when used in a religious space, the overall effect created by a sea of glittering, brightly-colored and gilded tesserae took precedence over literal realism. The goal of the artist was to create an overall feeling of awe, of being in a spiritual realm, or even the sense of being in the presence of God. Details were not supposed to distract from the main themes.
However, not all Byzantine mosaics were religious in nature. In fact, mosaic art was commonly used to decorate the floors and walls of public and private spaces with geometric patterns and secular figurative subjects.

Influence and legacy

Some Western art historians have dismissed or overlooked Byzantine art in general. For example, the deeply influential painter and historian Giorgio Vasari defined the Renaissance as a rejection of "that clumsy Greek style" ''. However, Byzantine artists and their mosaics in particular were highly influential on the rapidly expanding Islamic decorative arts, on Keivan Rus', and modern and contemporary artists across the world.
Islamic art began in the 7th century with artists and craftsmen mostly trained in Byzantine styles, and though figurative content was greatly reduced, Byzantine decorative styles remained a great influence on Islamic art.
As Eastern Orthodox Christianity spread northward and eastward, the Byzantine empire became economically and culturally tied to Keivan Rus'. In the late 10th century, Vladimir the Great introduced Christianity with his own baptism and, by decree, extended it to all inhabitants of Kiev. By the 1040s, Byzantine mosaic artists were working in the Hagia Sophia at Kiev, leaving a lasting legacy not only on Russian decorative arts but also medieval painting.
In the modern and contemporary eras, artists like Antoni Gaudí have continued to draw inspiration and influence from the indelible beauty of Byzantine mosaic art.
