The Philosophiae Consolatio of Boethius is subject to so many investigations that a periodical updating is inevitable. Even though the essential of the text remains the same, modifications and investigations on details are brought in every year. These can only be grouped in a completely renewed publication as has now been prepared by Professor L. Bieler. The present edition contains an introduction brought up to date by reference to new material, including manuscripts, that has come to light since the first edition; the correction of a few errors and misprints in the text; and a thorough overhaul of the fontes and the apparatus criticus on the basis of recent research. The indices have also been thoroughly revised.
