Question: The mosaic in the church in the city of the country having Hagios Demetrios is known as what?

full_context: Document 1: Cemetery Basilica (Thessaloniki): The Cemetery Basilica is an Early Christian basilica church located at Tritis Septemvriou Street in Thessaloniki, Greece. Only a portion of the building has been excavated, as the rest lies underneath the buildings of the Thessaloniki International Fair. The new Museum of Byzantine Culture is also located nearby.
Document 2: 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 3: Gytheio: Gytheio used to be an important port until it was destroyed in 4th century AD, possibly by an earthquake. Even thereafter its strategic location gave Gytheio a significant role in Maniot history. Today it is the largest and most important town in Mani. It is also the seat of the municipality of East Mani.
Document 4: 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 5: Hagios Demetrios: The Church of Saint Demetrius, or Hagios Demetrios (), is the main sanctuary dedicated to Saint Demetrius, the patron saint of Thessaloniki (in Central Macedonia, Greece), dating from a time when it was the second largest city of the Byzantine Empire. It is part of the site Palaeochristian and Byzantine Monuments of Thessaloniki on the list of World Heritage Sites by UNESCO since 1988.
Document 6: Mosaic: Jerusalem with its many holy places probably had the highest concentration of mosaic-covered churches but very few of them survived the subsequent waves of destructions. The present remains do not do justice to the original richness of the city. The most important is the so-called "Armenian Mosaic" which was discovered in 1894 on the Street of the Prophets near Damascus Gate. It depicts a vine with many branches and grape clusters, which springs from a vase. Populating the vine's branches are peacocks, ducks, storks, pigeons, an eagle, a partridge, and a parrot in a cage. The inscription reads: "For the memory and salvation of all those Armenians whose name the Lord knows." Beneath a corner of the mosaic is a small, natural cave which contained human bones dating to the 5th or 6th centuries. The symbolism of the mosaic and the presence of the burial cave indicates that the room was used as a mortuary chapel.
Document 7: 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 8: Hagia Sophia, Thessaloniki: The Hagia Sophia (, "Holy Wisdom") in Thessaloniki, Greece, is one of the oldest churches in that city still standing today. It is one of several monuments in Thessaloniki included as a World Heritage Site on the UNESCO list.
Document 9: Mosaic: In the Iconoclastic era, figural mosaics were also condemned as idolatry. The Iconoclastic churches were embellished with plain gold mosaics with only one great cross in the apse like the Hagia Irene in Constantinople (after 740). There were similar crosses in the apses of the Hagia Sophia Church in Thessaloniki and in the Church of the Dormition in Nicaea. The crosses were substituted with the image of the Theotokos in both churches after the victory of the Iconodules (787–797 and in 8th–9th centuries respectively, the Dormition church was totally destroyed in 1922).
Document 10: Hagia Sophia: Hagia Sophia (/ ˈhɑːɡiə soʊˈfiːə /; from the Greek: Αγία Σοφία, pronounced (aˈʝia soˈfia), ``Holy Wisdom ''; Latin: Sancta Sophia or Sancta Sapientia; Turkish: Ayasofya) was a Greek Orthodox Christian patriarchal basilica (church), later an imperial mosque, and is now a museum (Ayasofya Müzesi) in Istanbul, Turkey. From the date of its construction in 537 AD, and until 1453, it served as an Eastern Orthodox cathedral and seat of the Patriarch of Constantinople, except between 1204 and 1261, when it was converted by the Fourth Crusaders to a Roman Catholic cathedral under the Latin Empire. The building was later converted into an Ottoman mosque from 29 May 1453 until 1931. It was then secularized and opened as a museum on 1 February 1935. Famous in particular for its massive dome, it is considered the epitome of Byzantine architecture and is said to have`` changed the history of architecture''. It remained the world's largest cathedral for nearly a thousand years, until Seville Cathedral was completed in 1520.
Document 11: Mosaic: Christian mosaic art also flourished in Rome, gradually declining as conditions became more difficult in the Early Middle Ages. 5th century mosaics can be found over the triumphal arch and in the nave of the basilica of Santa Maria Maggiore. The 27 surviving panels of the nave are the most important mosaic cycle in Rome of this period. Two other important 5th century mosaics are lost but we know them from 17th-century drawings. In the apse mosaic of Sant'Agata dei Goti (462–472, destroyed in 1589) Christ was seated on a globe with the twelve Apostles flanking him, six on either side. At Sant'Andrea in Catabarbara (468–483, destroyed in 1686) Christ appeared in the center, flanked on either side by three Apostles. Four streams flowed from the little mountain supporting Christ. The original 5th-century apse mosaic of the Santa Sabina was replaced by a very similar fresco by Taddeo Zuccari in 1559. The composition probably remained unchanged: Christ flanked by male and female saints, seated on a hill while lambs drinking from a stream at its feet. All three mosaics had a similar iconography.
Document 12: 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 13: Military saint: The Eastern Orthodox Church considers Demetrius of Thessaloniki, Theodore Stratelates, Theodore of Amasea, and John the Warrior to be the patron saints of the military. Saint Nicholas is the patron saint of the Russian navy; all naval cathedrals are dedicated to this saint. Finally Prophet Elijah is the patron Saint of the Hellenic Army Aviation Arm.
Document 14: Mosaic: Only scant remains prove that mosaics were still used in the Early Middle Ages. The Abbey of Saint-Martial in Limoges, originally an important place of pilgrimage, was totally demolished during the French Revolution except its crypt which was rediscovered in the 1960s. A mosaic panel was unearthed which was dated to the 9th century. It somewhat incongruously uses cubes of gilded glass and deep green marble, probably taken from antique pavements. This could also be the case with the early 9th century mosaic found under the Basilica of Saint-Quentin in Picardy, where antique motifs are copied but using only simple colors. The mosaics in the Cathedral of Saint-Jean at Lyon have been dated to the 11th century because they employ the same non-antique simple colors. More fragments were found on the site of Saint-Croix at Poitiers which might be from the 6th or 9th century.
Document 15: Mosaic: The Church of the Holy Apostles in Thessaloniki was built in 1310–14. Although some vandal systematically removed the gold tesserae of the background it can be seen that the Pantokrator and the prophets in the dome follow the traditional Byzantine pattern. Many details are similar to the Pammakaristos mosaics so it is supposed that the same team of mosaicists worked in both buildings. Another building with a related mosaic decoration is the Theotokos Paregoritissa Church in Arta. The church was established by the Despot of Epirus in 1294–96. In the dome is the traditional stern Pantokrator, with prophets and cherubim below.
