Confessions

Augustine's 397–400 CE autobiographical prayer — the first autobiography in the Western tradition — following his intellectual wanderings through Manichaeism and Neo-Platonism to Christian conversion, and exploring the psychology of sin, grace, and the restless heart.

Created the first sustained first-person psychological narrative in Western literature — 'our heart is restless until it rests in Thee' — and provided the model for confessional, self-examining writing that runs from Rousseau to contemporary memoir.
