His travels through "Raška" (Old Serbia) were written down by a Jesuit priest Riggeputti as Relazione della Provincia della Rassia, who was collecting material for his work Illyricum Sacrum, a history of Christianity in the Balkans. Bošković described the historical and sacral monuments of Raška including Orthodox monasteries and royal palaces, and also commented on the "sad state" of the Roman Catholic Church in these lands under the Ottoman rule. After settling down in Dubrovnik, Nikola married a daughter of a local noble of Italian origin, Paola Bettera (Pavica Betera). The two had eight children, the second youngest, Ruđer Bošković (Roger Boscovich), being the most famous.
