frescoes from 1259. They form a second layer over the paintings from earlier centuries and represent one of the most complete and well-preserved monuments of medieval art in the Balkans. Eighteen scenes in the narthex depict the life of Saint Nicholas. The painter here drew certain aspects of contemporary lifestyle. In The Miracle at Sea, the ship and the sailors' hats recall the Venetian fleet. The portraits of the patrons of the church — Sebastocrator Kaloyan and his wife Dessislava, as well as those of Bulgarian tsar Constantine Tikh and Tsaritsa Irina, are thought to be among the most impressive and lifelike frescoes in the church, and are located on the north wall of the church. First layer The first layer of frescoes, which originally covered the entire eastern church, dates from the 11th–12th century. Fragments of those frescoes have been preserved in the lower parts of the apse and the north wall, and in the upper part of the west wall and the south vault. Second layer According to the donor’s inscription on the north wall of the second section, the second layer of frescoes dates from 1259. Those frescoes were painted over the earlier layer by a team of unknown artists, who also decorated the two floors of the building commissioned by Sebastocrator Kaloyan. The Boyana Church owes its world fame above all to the frescoes from 1259, which demonstrate the exceptional achievements of medieval Bulgarian culture. The majority of the more than 240 figures depicted here display individuality, remarkable psychological insight and vitality. The frescoes follow the canon of icon-painting established by the Seventh Ecumenical Council held in Nicaea in 787. The frescoes in the oldest section of the church include a magnificent representation of Christ Pantocrator in the dome. The drum below shows a host of angels, with the Four Evangelists – Matthew, Mark, Luke and John – portrayed in the pendentives. Four images of Christ adorn the face of the arches: Christ Emmanuel; Christ, The Ancient of Days; and the acheiropoietic (“made without hands”) Holy Mandylion and Holy Tile. Next come scenes from the Major Feast Days and the Passions of Christ. Among the full-length portrayals of saints in the first tier, there are ten warrior saints. The Virgin Enthroned, surrounded by archangels, is represented in the altar conch. Below are four church fathers: St. Gregory the Theologian, Basil the Great, John Chrysostom and Patriarch
