DE INDURATIONE CORDIS PHARAONIS. — A treatise that in the ninth century circulated under the name of St. Girolamo, but which certainly is not the work of the Saint. The author is probably Pelagius. The short treatise was discovered by the Benedictine Germain Morin, and its text was published after the death of the great scholar by De Plinval.
