In 1760 he became a monk and settled in the Rakovac Monastery, located in Srem,[3] where he wrote that he was an artist and icon painter and that in 1760 he received 6 ducats in prize money for his work.
He learned his art under the tutelage of Baroque painter Jov Vasiljevič who was the court painter of Patriarch Arsenije IV Jovanović Šakabenta.
