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.
Byzantine mosaics can trace their origin to 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, material that was also in use during the Hellenistic period. The use of tesserae enabled artists to create more colorful and finely-detailed images.
In 330 AD, the emperor Constantine moved the empire's capital from Rome to Byzantium (modern-day Istanbul), 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 (c.

Islamic art is a part of Islamic culture and encompasses the visual arts produced since the 7th century CE by people who lived within territories inhabited or ruled by Muslim populations. Referring to characteristic traditions across a wide range of lands, periods, and genres, Islamic art is a concept used first by Western art historians in the late 19th century. Public Islamic art is traditionally non-representational, except for the widespread use of plant forms, usually in varieties of the spiralling arabesque.
Byzantine architecture is the architecture of the Byzantine Empire, or Eastern Roman Empire. The Byzantine era is usually dated from 330 AD, when Constantine the Great established a new Roman capital in Byzantium, which became Constantinople, until the fall of the Byzantine Empire in 1453. However, there was initially no hard line between the Byzantine and Roman Empires, and early Byzantine architecture is stylistically and structurally distinguishable from earlier Roman architecture.
The landscape of computing is changing, thanks to the advent of modern networking equipment that allows machines to exchange information in as little as one microsecond. Such advancement has enabled microsecond-scale distributed computing, where entire dis ...

Byzantine machine learning (ML) aims to ensure the resilience of distributed learning algorithms to misbehaving (or Byzantine) machines. Although this problem received significant attention, prior works often assume the data held by the machines to be homo ...
