Z polemik XVII-wiecznych. Głos w sprawie kalendarza Kasjana Sakowicza

Kasjan (Kalikst) Sakowicz (about 1578-1647) was born as a son of orthodox priest. He studied in Zamojski Academy, Cracow University. From 1620 to1624, he was the rector of the orthodox school in Kiev. Sakowicz decided to become Basilian monk and later Augustinian monk. He wrote interesting polemical papers; for example: „Kalendarz Stary” (two versions) and others. Sakowicz published the chronological table to calculate Easter date up to 1933 year. Piotr Mohyła metropolitan of the Orthodox Church in the Polish-Lithuanian Commonwealth criticized Sakowicz’s arguments for the gregorian calendar use.
