Gedeon Chetvertinsky

Gedeon Chetvertinsky (1634–1690) was a Ruthenian prince and Orthodox hierarch born in Volhynia. In 1659 he became bishop of Lutsk and Ostroh, but after clashing with the Uniate Church he fled to Baturyn in 1684 under Hetman Ivan Samoilovych's protection.

In 1685 a Kyiv synod proclaimed him metropolitan, and that October Patriarch Joachim of Moscow installed him as Metropolitan of Kyiv, Galicia and all Ruthenia. In 1686 Constantinople permitted Moscow to control Kyiv's metropolitans. After Samoilovych's fall, he lost the style of all Ruthenia in 1688, and he died at Kyiv in 1690.
