2. De Paradiso. This is the earliest or one of the earliest of the extant writings of St. Ambrose, though the exact date is uncertain. In it he discusses what and where Paradise was, and the question of the life of our first parents there, the temptation, fall and its results, and answers certain cavils of the Gnostics and Manichees. He also enters into an allegorical exposition comparing Paradise with the human soul.
