13 books, by St. Augustine of Hippo, written in Latin between AD 397 and 400.[1]

Modern English translations of it are sometimes published under the title The Confessions of St. Augustine in order to distinguish the book from other books with similar titles. Its original title was Confessions in Thirteen Books, and it was composed to be read out loud with each book being a complete unit.

The work outlines St. Augustine's sinful youth and his conversion to Christianity. It is widely seen as the first Western autobiography ever written, and was an influential model for Christian writers throughout the following 1,000 years, through the Middle Ages. It is generally considered one of Augustine's most important texts.
