angels, Apostles and Theotokos. This composition is inspired by the mosaics in the main dome of St Mark's Basilica in Venice. The lower sections are influenced by the Gospel of Luke and the first narratives of the Acts of the Apostles. The texts held by the angels are written in the Church Slavonic language, while the names of the depicted persons are written in Greek. The first indicates pan-Slavic sentiment while the latter connects it to the Byzantine traditions. The total painted area of the dome is . It is one of the largest curved areas decorated with the mosaic techniques and when the work is completely finished, Saint Sava will be the 6th-largest church building in the world ornamented this way after St. Peter's Basilica in Vatican City, the People's Salvation Cathedral in Bucharest (also unfinished), the Basilica of the National Shrine of the Immaculate Conception in Washington, D.C, Primatial Basilica of the Blessed Virgin Mary in Esztergom and Berlin Cathedral. The mosaic was created for over a year in Russia, during 2016 and 2017. It was then cut and transported by special trucks to Belgrade. The total weight of the mosaic is 40 tons and it was placed on the dome from May 2017 to February 2018. The 3,289 m2 mosaic installed at the eastern wing section, the side of the altar covers 3,289 m2. Materials used The material for the tessera is produced by Smaltfactory in Moscow. The enterprise's gold mosaics use pure gold (24k). It is reasonable to suggest that for approximately 400 tonnes of mosaic in total, that a great part of the costs comes from the price of precious materials. Beside pure gold, a great deal of the tessera also has pure silver in its content. The pure precious metal content prevents the materials from changing as time passes. Only pure gold's natural colour is not changed by the high temperatures during the smelting process in the kiln. The highly reflective properties of the gold tessera and the differences of angles where the mosaics are installed will produce differences in reflection, a technique that is used to blur the background and constructive elements of a church's interior. Sculptures Capitals and cornices show a variety of sculptures. The heraldic symbols of the Nemanjić-Dynasty are a dominant motif. Floral motifs and anthropomorphic figures are inspired by the rich sculptural tradition of the Morava school. The main
