Monastic Life and Commemoration
Sisoes belonged to the monastic community of the Kiev Caves and is associated specifically with the Far Caves, the section of the underground complex also known as the Caves of Theodosius. As a schemamonk he had taken on the Great Schema, the most demanding form of the monastic vocation.
His memory is preserved chiefly through the collective commemoration of the Far Caves fathers. The fifth ode of the canon for that service joins his name with that of Gregory the Faster, recalling that both restrained their passions through fasting.
