Dominik Mandić, while researching the history of the Diocese of Duvno, could not find any documents on him, thus being unable to determine whether John of Hoio ever served as the residential bishop in Duvno.

Madius was a prelate of the Catholic Church who served as the bishop of Duvno from between 1298 and 1311 to his resignation in 1344.

During his episcopate, he was involved in long-lasting litigations against the archbishops of Split as a representative of Bishop Valentin of Makarska over the control of Omiš and other church objects. Madius resigned due to what he calls "maliciousness of the people", which might refer to the opposition of his faithful to pay taxes and the political plight which befell him after his patrons from the Šubić family lost the political influence after the conquest of their domains by Stephen II, Ban of Bosnia. He nevertheless retained the title of a bishop and, according to Ante Škegro, lived on the territory of the Archdiocese of Split.
