In slightly less than a thousand lines, the poem describes the conflict of vices and virtues as a battle in the style of Virgil's Aeneid. Christian faith is attacked by and defeats pagan idolatry to be cheered by a thousand Christian martyrs. Chastity is assaulted by lust, but cuts down her enemy with a sword. Anger attacks patience, is unable to defeat her and destroys herself instead. In a similar manner, various vices fight corresponding virtues and are always defeated. Biblical figures that exemplify these virtues also appear (e.g. Job as an example of patience).
