Life at the Kiev Caves
The Kiev Caves Lavra (Kyevo-Pecherska Lavra) was founded in the eleventh century by the Venerable Anthony and Theodosius of the Caves and became the mother monastery of Russian monasticism. Pimen lived within this community in the twelfth century, residing in the Near Caves section associated with Anthony. Hagiographic accounts of the Caves fathers are preserved in the Kyiv-Pechersk Paterikon, a collection of monastic narratives compiled in the thirteenth century that draws on earlier written and oral sources.
The tradition that Pimen was sick from birth and that his illness preserved him from spiritual harm reflects a wider ascetic theology in which bodily affliction voluntarily accepted — or providentially given — is understood as a form of mortification equivalent to fasting and vigil. His epithet "the Much-Ailing" (Mnogoboleznennyj in Slavonic) distinguishes him from other Pimens venerated at the Caves, notably Pimen the Faster who rests in the Far Caves and is also commemorated on 7 August.
