Question: What is the mosaic in the church in the city where Elias of Enna died known as?

full_context: Document 1: 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 2: 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 3: John A. Saliba: John A. Saliba is a Maltese-born Jesuit priest, a professor of religious studies at the University of Detroit Mercy and a noted writer and researcher in the field of new religious movements.
Document 4: 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 5: 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 6: Athanasius of Alexandria: Nonetheless, within a few years of his death, Gregory of Nazianzus called him the "Pillar of the Church". His writings were well regarded by all Church fathers who followed, in both the West and the East, who noted their rich devotion to the Word-become-man, great pastoral concern, and profound interest in monasticism. Athanasius is counted as one of the four great Eastern Doctors of the Church in the Roman Catholic Church. In the Eastern Orthodox Church, he is labeled the "Father of Orthodoxy". Some Protestants label him "Father of the Canon". Athanasius is venerated as a Christian saint, whose feast day is 2 May in Western Christianity, 15 May in the Coptic Orthodox Church, and 18 January in the other Eastern Orthodox Churches. He is venerated by the Oriental and Eastern Orthodox Churches, the Roman Catholic Church, the Lutherans, and the Anglican Communion.
Document 7: Gregory of Nyssa: Gregory of Nyssa, also known as Gregory Nyssen (; c. 335 – c. 395), was bishop of Nyssa from 372 to 376 and from 378 until his death. He is venerated as a saint in Roman Catholicism, Eastern Orthodoxy, Oriental Orthodoxy, and Anglicanism. Gregory, his elder brother Basil of Caesarea, and their friend Gregory of Nazianzus are collectively known as the Cappadocian Fathers.
Document 8: 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 9: 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 10: 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 11: Book of Revelation: Tradition links him to John the Apostle, but it is unlikely that the apostle could have lived into the most likely time for the book's composition, the reign of Domitian, and the author never states that he knew Jesus. All that is known is that this John was a Jewish Christian prophet, probably belonging to a group of such prophets, and was accepted as such by the congregations to whom he addresses his letter. His precise identity remains unknown, and modern scholarship commonly refers to him as John of Patmos.
Document 12: Elias of Enna: Saint Elias of Enna, born John Rachites (; 822/823 in Enna – August 17, 903 in Thessaloniki), is venerated as a saint by the Catholic Church and the Orthodox Church. Elias is also known as Saint Elias the Younger, or Junior, to distinguish him from the biblical prophet Elijah. He lived a very adventurous life during the ninth century and was the protagonist of repeated ups and downs. He is commemorated on Aug. 17.
Document 13: Elias Zoghby: Elias Zoghby was born on January 9, 1912, in Cairo. His mother, Hanne Ishak Yared, was a Melkite Greek Catholic and his father, Abdallah Mikail Zoghby, was an Antiochian Orthodox convert and former Maronite Catholic. The couple had recently emigrated from Lebanon and settled in Cairo's Arb-el-Guenena neighborhood. The area had a Melkite church nearby which his parents attended. Elias and his siblings were baptized into the Melkite faith and raised in a devout household, attending liturgy daily, reading the bible together as a family and praying the Office every afternoon.
Document 14: 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 15: 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.
