In 1561 Serbian Orthodox monks Jovan Maleševac and Matija Popović began working with the Protestant reformer Primož Trubar at Urach in Germany. Their collaboration aimed to print New Testament and religious books in Cyrillic letters. It was an unusual cross-confessional effort to reach South Slavic readers.

The project shows how print could serve minority languages and scripts across religious boundaries. It also links oral sermon culture, vernacular scripture and the preservation of Slavic literary identities under imperial pressure.
