Input: Consider Input: Question: How old was Jovan Rajic when he became a priest in Kovilj? Passage:The present, stone church, was built from 1741 to 1749 by the neimars (builders) Teodor Kosta and Nikola Krapic. It was built in the Morava architectural school style of Serbo-Byzantine architecture and patterned after Manasija and Ravanica. In 1758, Empress Maria Theresa issued a document which set the monastery's estate. By the imperial privilege, the land was strictly divided between the monastery and the nearby settlement of Koviljski Sanac. The establishment of the Sajkas Battalion in 1763, Serbian settlements surrounding the monastery were repopulated and preserved, which also influenced the prosperity of the monastery. Forerunner of the modern Serbian historiography, Jovan Rajic, became a priest in Kovilj and was appointed the archimandrite of the monastery in 1772, where he died in 1801. During the Hungarian Revolution of 1848, the rebels used the monastery as their base in 1849 which forced the monks to move across the Danube, into the Syrmia region. When they returned after the collapse of the rebellion, the monastery was looted and burned, and many historical treasures have been lost. The new church damaged inside while the old one was almost completely ruined, so it was demolished in 1850. Since 1850, the monks began to collect funds for the restoration. Some of it was secured by the Austrian state, some by the donations of the population and some was help from Russia. Young painter Aksentije Marodic has painted the new iconostas in the 1880s, including the scenes from the life of Christ and replicas of the most famous paintings from that period which Marodic copied from the galleries in Vienna, Munich, Paris, Rome, Venice, and Naples. The walls themselves are not painted. Woodworks and carvings are work of Jovan Kisner, while the gold plating and marble work were done by Ludvig Taus. The work on the interior turned out to be quite lengthy, as it lasted until 1891/92.
