Antony of Siya was a 16th-century Russian Orthodox monk and iconographer who established a significant monastic community in the Russian North. Born a peasant in 1478, he married in his early adulthood before entering a monastery in Kargopol following the death of his wife. After spending time wandering the shores of the Arctic Ocean, he founded the Antonievo-Siysky Monastery in 1520 on the Siya River. He operated under the jurisdiction of the archbishop of Novgorod and held land granted by Vasily III.
Life and work

Following his time as a wanderer, Antony founded his monastery in 1520. He was an iconographer and advocated for monastic control over the local peasantry. His settlement, located on the Siya River, grew under the authority of the Novgorod archbishop. He remained active in his monastic duties until his death in 1556 at the Antonievo-Siysky Monastery.
Veneration and legacy

Recognized as a national saint in 1610, he is known as the Venerable. His life has been documented in historical writings, including a biography by Ivan and a vita composed by Jonah in 1578. He remains a respected figure within the Orthodox tradition due to his foundational role in northern monasticism.
