A mosaic (/moʊˈzeɪɪk/) is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world.
Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms.
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.
There are two main types of mosaic surviving from this period: wall mosaics in churches, and sometimes palaces, made using glass tesserae, sometimes backed by gold leaf for a gold ground effect, and floor mosaics that have mostly been found by archaeology. These often use stone pieces, and are generally less refined in creating their images. Survivals of secular wall-mosaics are few, but they show similar subject matter to floor mosaics, where many of the subjects are very similar in both churches and houses; it was not acceptable for images of sacred figures to be walked upon. Religious mosaics show similar subject matter to that found in other surviving religious Byzantine art in painted icons and manuscript miniatures. Floor mosaics often have images of geometrical patterns, often interspersed with animals. Scenes of hunting and venatio, arena displays where animals are killed, are popular.
Early Byzantine mosaics in the Middle East are a group of Christian mosaics created between the 4th and the 8th centuries in ancient Syria, Israel, Palestine, Transjordan and Egypt when the area belonged to the Byzantine Empire. The eastern provinces of the Eastern Roman Empire and its continuation, the Byzantine Empire, inherited a strong artistic tradition from pagan Late Antiquity. The tradition of making mosaics was carried on in the Umayyad era until the end of the 8th century. The great majority of these works of art were later destroyed but archeological excavations unearthed many surviving examples.
The Basilica of Sant'Apollinare Nuovo is a basilica church in Ravenna, Italy. It was erected by the Ostrogothic king Theodoric the Great as his palace chapel during the first quarter of the 6th century (as attested to in the Liber Pontificalis). This Arian church was originally dedicated in 504 AD to "Christ the Redeemer". It's present dedication dates only from the 9th century. The basilica's current façade, which features a portico, dates to the 16th century, while the adjacent tower dates to the 10th century.
It was reconsecrated in 561 AD, under the rule of the Byzantine emperor Justinian I, under the new name "Sanctus Martinus in Coelo Aureo" ("Saint Martin in Golden Heaven"). Suppressing the Arian church, Justinian rededicated the church to Saint Martin of Tours, a foe of Arianism. According to legend, Pope Gregory the Great ordered that the mosaics in the church be blackened, as their golden glory distracted worshipers from their prayers. The basilica was renamed again in 856 AD when relics of Saint Apollinaris were transferred from the Basilica of Sant'Apollinare in Classe because of the threat posed by frequent raids of pirates from the Adriatic Sea.
Madaba (Arabic: مادبا; Biblical Hebrew: מֵידְבָא Mēḏəḇāʾ; Ancient Greek: Μήδαβα) is the capital city of Madaba Governorate in central Jordan, with a population of about 60,000. It is best known for its Byzantine and Umayyad mosaics, especially a large Byzantine-era mosaic map of the Holy Land. Madaba is located 30 kilometres (19 miles) south-west of the capital Amman.
Maestà [maeˈsta], the Italian word for 'majesty', designates a classification of images of the enthroned Madonna with the child Jesus, the designation generally implying accompaniment by angels, saints, or both. The Maestà is an extension of the "Seat of Wisdom" theme of the seated "Mary Theotokos", "Mary Mother of God", which is a counterpart to the earlier icon of Christ in Majesty, the enthroned Christ that is familiar in Byzantine mosaics. Maria Regina is an art historians' synonym for the iconic image of Mary enthroned, with or without the Child.
In the West, the image seems to have developed from Byzantine precedents such as the coin of Constantine's Empress Fausta, crowned and with their sons on her lap and from literary examples, such as Flavius Cresconius Corippus's celebration of Justin II's coronation in 565. Paintings depicting the Maestà came into the mainstream artistic repertory, especially in Rome, in the late twelfth and early thirteenth centuries, with an increased emphasis on the veneration of Mary. The Maestà was often executed in fresco technique directly on plastered walls or as paintings on gessoed wooden altar panels.
