Transferring Jerusalem To Moscow: Maksim Grek’S Letter And Its Afterlife, Justin Willson Feb 2023

Transferring Jerusalem To Moscow: Maksim Grek’S Letter And Its Afterlife, Justin Willson

Faculty Scholarship

Few debates in late seventeenth-century Muscovy were as heated as the controversy over the naming of the Resurrection “New Jerusalem” Monastery (1656). This essay draws attention to an overlooked sixteenth-century source, a letter by the Greek-born Slavic translator Maksim Grek (d. 1556), which played an important role in shaping the Church’s thinking. Maksim’s letter helps to explain why Jerusalem ideology took a very different path in Russia than it did in Western Europe, and why replications of the Holy Sepulcher are only very rarely encountered in Muscovy. Maksim’s letter introduces several themes which foreshadow the course of the later debate: …
