Dante's Purgatory consists of seven terraces located on a mountain island in the southern hemisphere. Souls arrive via boat guided by an angel to purge themselves of venial sins through different punishments and prayers on each terrace representing the seven deadly sins: pride, envy, wrath, sloth, greed, gluttony, and lust. As Dante ascends he witnesses stories and sculptures depicting the opposite virtues and has the corresponding letter for each sin erased from his forehead by an angel's touch.
