De consideratione
De consideratione is a book of five parts by Bernard of Clairvaux; the great 12th-century abbot wrote it for (or rather, to) his fellow Cistercian monk who had become Pope Eugenius III. The book is famous for its portrayal of a church leader in a conflict between devotion to God and the demands of the papal court. The book was written between 1148 and 1152, late in Bernard's life.
