This poem is full of sensory information. In the medieval period, people believed that the mind was made up of three parts; senses, which took in raw information from the outside, imagination, which translated this information into forms that could be understood (often allegorical or associative), and reason, which ordered this information and forms and made sense of it. Choose one instance of sensory information (sound, feeling, visuals), and describe how it rises through imagination and reason. For example, take the sound that precedes the angel's arrival at Dis. What does he sound like (sense)?
