The Transfiguration Church in Kovalyovo was built around 1345. The southern annex is thought to have been designed as the burial vault of the Zhabin family. The church was notable for the frescoes created in the 14th century. During the Second World War, between 1941 and 1943, the church was destroyed. After the war, the ruins were conserved. In the 1960s, fragments of the frescoes were restored. Only 16 square metres originally survived, but the restorers (led by Alexander Grekov and Valentina Grekova) managed to retrieve about 160 square metres of frescoes from the debris. In 1970, the church was rebuilt to a design by Leonid Krasnorechyev.
The church is constructed in brick, and has one dome. It has a single apse and four square columns. This design is typical for pre-Mongol Novgorod churches. There are two auxiliary chapels of different size flanking the main building from the south and from the north. The south chapel has a set of limestone crosses inserted in the walls. The system of vault roofing features three semicircular wall gables (zakomara) which hark back to the pre-Mongol period. The pillars are square rather than circular or octagonal, as was typical for the 14th century.
The frescoes, created ca. 1380, covered the apse, the inner surface of the dome, the southern and the northern walls of the church, some of the pillars, and the interior of the western chapel. They were sponsored by Afanasy Stepanovich and his wife. The frescoes are thought to have been painted by a team of Balkan (possibly Serbian) painters. Their static and hieratic style has little in common with other Novgorodian frescoes of the period; but it shares similarities with the older Byzantine tradition. The total area of the frescoes was 450 square metres.
The interior of the dome was filled with images of the prophets. But it is the images of warrior saints that predominate. This is usually explained by the fact that in the 1370s the Grand Duchy of Moscow, with the support of other Russian states, was preparing to fight against the Golden Horde, culminating in 1380 with the Battle of Kulikovo. There is also the first Russian image of the dead Jesus Christ in the tomb.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
