A box of Latin manuscripts comes to light in an Argentine flea market. An apocyphral invention by some 17th or 18th century scolar, or a transcrpit of what it appears to be - a hitherto unheard of letter to St Augustine to a woman he renounced for chastity? VITA BREVIS is both an entrancing human document and a fascinating insight into the life and philosophy of St.Augustine. Gaarder'sinterpretation of Floria's letter is as playful, inventive and questioning as SOPHIE'S WORLD.
