Zacharias Kopystensky

Zacharias Kopystensky (died 21 March 1627), born in Przemyśl, was an Orthodox cleric and writer in the Polish-Lithuanian Commonwealth. Educated at the Ostroh Academy, he entered the Kyiv Pechersk Lavra and in 1624 succeeded Yelisey Pletenetsky as its archimandrite.

His chief work, Palinodiia (1621–1623), defended Eastern Orthodoxy against the Ruthenian Uniate Church, and he translated the Horologion and works of John Chrysostom. The Hustyn Chronicle, a history of the old Rus' lands to 1598, has also been attributed to him.
