Commentary Inf II 41

For the importance of the word impresa in the overall economy of the poem see Holl.1969.1, p. 230. It occurs twice in this canto (next at [Inf II 47]), where it refers to Dante's journey, then in [Inf XXXII 7], where it refers to the poem that Dante is writing, and finally in [Par XXXIII 95], where it surely refers to the voyage, and perhaps to the poem as well. See C.Inf.XXXII.109.
