Information about the life of the Venerable Sisoes the Schema-Monk, like many ascetics of the Kiev Caves Lavra of the 13th century, is very scarce.
He was first mentioned in the plan of the Near Caves in 1661 as "Sisoes the Faster". In 1703 he was marked as "Sisoes the Recluse".
His relics rest in the Near Caves, and is commemorated on October 24th.
