Prudentius (born in 348 in northern Spain, died after 405) spent most of his life following worldly pursuits, but later turned to writing, in which he aimed to glorify God and atone for his earlier sins. One of his most popular works is a poem called Psychomachia (Conflict of the Soul), which describes the battles between female personifications of human virtues and vices.
