Question: When were the mosaics at the church where the Salonika Agreement took place created?

full_context: Document 1: Josip Broz Tito: After the Partisans managed to endure and avoid these intense Axis attacks between January and June 1943, and the extent of Chetnik collaboration became evident, Allied leaders switched their support from Draža Mihailović to Tito. King Peter II, American President Franklin Roosevelt and British Prime Minister Winston Churchill joined Soviet Premier Joseph Stalin in officially recognising Tito and the Partisans at the Tehran Conference. This resulted in Allied aid being parachuted behind Axis lines to assist the Partisans. On 17 June 1944 on the Dalmatian island of Vis, the Treaty of Vis (Viški sporazum) was signed in an attempt to merge Tito's government (the AVNOJ) with the government in exile of King Peter II. The Balkan Air Force was formed in June 1944 to control operations that were mainly aimed at aiding his forces.
Document 2: Vladimir Stoychev: In 1944, Stoychev became a member of the Fatherland Front's Bureau of the National Committee. During World War II, Stoychev was in command of the Bulgarian First Army after the country switched allegiance to the Allies. Under Stoychev, the Bulgarian First Army helped the Red Army and Yugoslav Partisans drawing the Nazis out of much of Yugoslavia and Hungary, reaching the Austrian Alps by May 1945. On 8 May 1945, Vladimir Stoychev signed a demarkation agreement with British V Corps commander Charles Keightley in southern Austria. On 24 June 1945, he took part in the Moscow Victory Parade.
Document 3: Greece: At the end of the Balkan Wars, the extent of Greece's territory and population had increased. In the following years, the struggle between King Constantine I and charismatic Prime Minister Eleftherios Venizelos over the country's foreign policy on the eve of World War I dominated the country's political scene, and divided the country into two opposing groups. During parts of the First World War, Greece had two governments; a royalist pro-German government in Athens and a Venizelist pro-Britain one in Thessaloniki. The two governments were united in 1917, when Greece officially entered the war on the side of the Triple Entente.
Document 4: 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 5: Salonika Agreement: The Salonika Agreement (also called the Thessaloniki Accord) was a treaty signed on 31 July 1938 between Bulgaria on the one hand and the Balkan Entente—the states of Greece, Romania, Turkey and Yugoslavia—on the other. The signatories were, for the former, Prime Minister Georgi Kyoseivanov and, for the latter, in his capacity as President of the Council of the Balkan Entente, Ioannis Metaxas, Prime Minister and Foreign Minister of Greece.
Document 6: 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 7: 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 8: Bulgaria during World War I: The military convention between Bulgaria and the Central Powers laid down the general plan for its campaign against the Kingdom of Serbia. It severely limited the control of the Bulgarian High Command over the Bulgarian 1st Army, which was designated part of a combined German, Bulgarian and Austro - Hungarian force commanded by Field Marshal August von Mackensen. He had recently led the German and Austro - Hungarian armies in the highly successful and victorious Gorlice -- Tarnów Offensive of the Central Powers against the Russian army on the Eastern Front. His army group was created specifically to wage war against the Serbian army in the pre-1913 borders of the country (``Old Serbia ''), to defeat it wherever it found it and to open the land route between Hungary and Bulgaria. As commander, Mackensen acted independently and received his directives only from the German High Command. However, the field marshal's orders to his Bulgarian forces had to be relayed to the commander of the 1st Army by the Bulgarian General Staff, which left room for the latter to intervene when needed. According to the convention, the Bulgarian commander - in - chief retained full and direct control over the Bulgarian 2nd Army and its operations in Vardar Macedonia.
Document 9: 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 10: 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 11: 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 12: Josip Broz Tito: On 12 September 1944, King Peter II called on all Yugoslavs to come together under Tito's leadership and stated that those who did not were "traitors", by which time Tito was recognized by all Allied authorities (including the government-in-exile) as the Prime Minister of Yugoslavia, in addition to commander-in-chief of the Yugoslav forces. On 28 September 1944, the Telegraph Agency of the Soviet Union (TASS) reported that Tito signed an agreement with the Soviet Union allowing "temporary entry" of Soviet troops into Yugoslav territory which allowed the Red Army to assist in operations in the northeastern areas of Yugoslavia. With their strategic right flank secured by the Allied advance, the Partisans prepared and executed a massive general offensive which succeeded in breaking through German lines and forcing a retreat beyond Yugoslav borders. After the Partisan victory and the end of hostilities in Europe, all external forces were ordered off Yugoslav territory.
Document 13: Michael Sionidis: Following the end of World War I, Sionidis, as president of Matsikovo community, retrieved the remains of nine "evzones" whom the Bulgarians had killed during the Second Balkan War, and buried them in his village. In 1927, the "" renamed Matsikovo to Evzonoi in their honour. Michael Sionidis died in 1935.
Document 14: 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 15: 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.
