Guido degli Anastagi appears as the knight of Nastagio degli Onesti’s vision in Filomena’s fifth tale (V, 8). When the lady he loved refused his attentions, he earned eternal damnation by committing suicide. In hell, his punishment is to chase his lady through the Italian countryside, hunting her down and killing her like an animal each day. In this way, he is enacting hatred towards she whom he loved in life. His story enables Nastagio to convince his own lady, Paolo’s Daughter, to reconsider refusing Nastagio’s love.
