Document 4: Cyprus: Popular music in Cyprus is generally influenced by the Greek Laïka scene; artists who play in this genre include international platinum star Anna Vissi, Evridiki, and Sarbel. Hip Hop, R&B and reggae have been supported by the emergence of Cypriot rap and the urban music scene at Ayia Napa. Cypriot rock music and Éntekhno rock is often associated with artists such as Michalis Hatzigiannis and Alkinoos Ioannidis. Metal also has a small following in Cyprus represented by bands such as Armageddon (rev.16:16), Blynd, Winter's Verge and Quadraphonic.
Document 5: Mosaic: Important fragments survived from the mosaic floor of the Great Palace of Constantinople which was commissioned during Justinian's reign. The figures, animals, plants all are entirely classical but they are scattered before a plain background. The portrait of a moustached man, probably a Gothic chieftain, is considered the most important surviving mosaic of the Justinianian age. The so-called small sekreton of the palace was built during Justin II's reign around 565–577. Some fragments survive from the mosaics of this vaulted room. The vine scroll motifs are very similar to those in the Santa Constanza and they still closely follow the Classical tradition. There are remains of floral decoration in the Church of the Acheiropoietos in Thessaloniki (5th–6th centuries).
Document 6: Mosaic: Mosaic art also flourished in Christian Petra where three Byzantine churches were discovered. The most important one was uncovered in 1990. It is known that the walls were also covered with golden glass mosaics but only the floor panels survived as usual. The mosaic of the seasons in the southern aisle is from this first building period from the middle of the 5th century. In the first half of the 6th century the mosaics of the northern aisle and the eastern end of the southern aisle were installed. They depict native as well as exotic or mythological animals, and personifications of the Seasons, Ocean, Earth and Wisdom.
Document 7: I Knew Them: I Knew Them is a band that originates from Thessaloniki, Greece. However, it is a band that differentiates itself from the Greek rock movement, introducing elements from foreign rock styles such as the Grunge movement from Seattle, USA during the late 1980s and New York City's No-Wave from the early 1980s. They are one of the few Greek rock bands that took their music way beyond the limits of Greece, more evidently by moving to the United Kingdom in 2006. It is also notable that they still retain all creative control of their creations, having non-exclusive cooperation with many indie labels from around the world.
Document 8: Mosaic: In the 5th-century Ravenna, the capital of the Western Roman Empire, became the center of late Roman mosaic art. The Mausoleum of Galla Placidia was decorated with mosaics of high artistic quality in 425–430. The vaults of the small, cross-shaped structure are clad with mosaics on blue background. The central motif above the crossing is a golden cross in the middle of the starry sky. Another great building established by Galla Placidia was the church of San Giovanni Evangelista. She erected it in fulfillment of a vow that she made having escaped from a deadly storm in 425 on the sea voyage from Constantinople to Ravenna. The mosaics depicted the storm, portraits of members of the western and eastern imperial family and the bishop of Ravenna, Peter Chrysologus. They are known only from Renaissance sources because almost all were destroyed in 1747.
Document 9: Freshlyground: Freshlyground is a South African Afro-fusion band that formed in Cape Town in 2002. The band members have different backgrounds, including South Africa, Mozambique, and Zimbabwe. Freshlyground's musical style blends elements of traditional South African music (such as kwela and African folk music), blues, jazz, and features of indie rock. They are best known for their performance "Waka Waka (This Time for Africa)" with Colombian singer Shakira, which received worldwide recognition. The music video - featuring the group - also received over 1.70 billion views on YouTube.
Document 10: Mosaic: The 9th- and 10th-century mosaics of the Hagia Sophia in Constantinople are truly classical Byzantine artworks. The north and south tympana beneath the dome was decorated with figures of prophets, saints and patriarchs. Above the principal door from the narthex we can see an Emperor kneeling before Christ (late 9th or early 10th century). Above the door from the southwest vestibule to the narthex another mosaic shows the Theotokos with Justinian and Constantine. Justinian I is offering the model of the church to Mary while Constantine is holding a model of the city in his hand. Both emperors are beardless – this is an example for conscious archaization as contemporary Byzantine rulers were bearded. A mosaic panel on the gallery shows Christ with Constantine Monomachos and Empress Zoe (1042–1055). The emperor gives a bulging money sack to Christ as a donation for the church.
Document 11: Mosaic: Important Justinian era mosaics decorated the Saint Catherine's Monastery on Mount Sinai in Egypt. Generally wall mosaics have not survived in the region because of the destruction of buildings but the St. Catherine's Monastery is exceptional. On the upper wall Moses is shown in two panels on a landscape background. In the apse we can see the Transfiguration of Jesus on a golden background. The apse is surrounded with bands containing medallions of apostles and prophets, and two contemporary figure, "Abbot Longinos" and "John the Deacon". The mosaic was probably created in 565/6.
Document 12: Mosaic: Very few early Byzantine mosaics survived the Iconoclastic destruction of the 8th century. Among the rare examples are the 6th-century Christ in majesty (or Ezekiel's Vision) mosaic in the apse of the Church of Hosios David in Thessaloniki that was hidden behind mortar during those dangerous times. Nine mosaic panels in the Hagios Demetrios Church, which were made between 634 and 730, also escaped destruction. Unusually almost all represent Saint Demetrius of Thessaloniki, often with suppliants before him.
Document 13: Mosaic: The greatest mosaic work of the Palaeologan renaissance in art is the decoration of the Chora Church in Constantinople. Although the mosaics of the naos have not survived except three panels, the decoration of the exonarthex and the esonarthex constitute the most important full-scale mosaic cycle in Constantinople after the Hagia Sophia. They were executed around 1320 by the command of Theodore Metochites. The esonarthex has two fluted domes, specially created to provide the ideal setting for the mosaic images of the ancestors of Christ. The southern one is called the Dome of the Pantokrator while the northern one is the Dome of the Theotokos. The most important panel of the esonarthex depicts Theodore Metochites wearing a huge turban, offering the model of the church to Christ. The walls of both narthexes are decorated with mosaic cycles from the life of the Virgin and the life of Christ. These panels show the influence of the Italian trecento on Byzantine art especially the more natural settings, landscapes, figures.
Document 14: Mosaic: There are very few existing mosaics from the Komnenian period but this paucity must be due to accidents of survival and gives a misleading impression. The only surviving 12th-century mosaic work in Constantinople is a panel in Hagia Sophia depicting Emperor John II and Empress Eirene with the Theotokos (1122–34). The empress with her long braided hair and rosy cheeks is especially capturing. It must be a lifelike portrayal because Eirene was really a redhead as her original Hungarian name, Piroska shows. The adjacent portrait of Emperor Alexios I Komnenos on a pier (from 1122) is similarly personal. The imperial mausoleum of the Komnenos dynasty, the Pantokrator Monastery was certainly decorated with great mosaics but these were later destroyed. The lack of Komnenian mosaics outside the capital is even more apparent. There is only a "Communion of the Apostles" in the apse of the cathedral of Serres.
Document 15: The Gurdjieff Ensemble: "The Gurdjieff Folk Instruments Ensemble" based in Armenia was founded in 2008, and is led by the Armenian musician, Levon Eskenian. The Ensemble’s awards include the prestigious Dutch Edison Award: Best World Music Album 2012 and Armenian National Music Award: Best Folk Music Album 2011, for their album, “Music of Georges I. Gurdjieff,’’ produced by ECM Records. The ensemble consists of Armenia’s leading practitioners of traditional music performing on Duduk, Blul, Kamancha, Oud, Kanōn, Santur, Tar/Saz, Dap/Daf, Dhol, and Tombak. The repertoire is composed of the “mystic and spiritual teacher,” George I. Gurdjieff's Armenian, Greek, Assyrian, Arabic, Kurdish, Caucasian spiritual and folk music, authentically arranged for Eastern instruments by Eskenian. The repertoire also includes additional Eastern music that exemplifies Gurdjieff’s musical influences during his travels in the East.
