Radogost or Radigost (latinized as Rhadagastus; Serbian Cyrillic: Радогост/Радигост) was a Catholic clergyman who served as Bishop of Bosnia in the late 12th century.
[1] On that occasion, Radogost brought presents for Pope Clement III from Ban Kulin, ruler of Bosnia.
The historian John Van Antwerp Fine, Jr. dismisses the chronicler Mavro Orbini's date of 1171 because there is no evidence that Kulin was already Ban of Bosnia at that time.
[1] He justified his celebration of mass in Church Slavonic to his metropolitan, claiming that this was a privilege granted to his predecessors by Pope John VIII in 880.
It is unknown whether he died before or after the Abjuration of Bilino Polje, whereby Kulin and his closest associates agreed on the future management of the Catholic Church in Bosnia.
