The Epitaph of Monks
This book is in Latin.
A short book on the narrow way of the just to the kingdom of heaven: guarding the heart, calling on the names of Jesus and Mary, the soul's true consolation, silence, the cleansing of the heart. Latin only: Pohl's critical edition (Freiburg 1918), from a raw OCR of the printed volume; no public-domain English translation has been found.
