Blake's illustrations of the poem are not merely accompanying works, but rather seem to critically revise, or furnish commentary on, certain spiritual or moral aspects of the text.
Because the project was never completed, Blake's intent may be obscured. Some indicators bolster the impression that Blake's illustrations in their totality would take issue with the text they accompany: In the margin of Homer Bearing the Sword and His Companions, Blake notes, "Every thing in Dantes Comedia shews That for Tyrannical Purposes he has made This World the Foundation of All & the Goddess Nature & not the Holy Ghost." Blake seems to dissent from Dante's admiration of the poetic works of ancient Greece, and from the apparent glee with which Dante allots punishments in Hell (as evidenced by the grim humour of the cantos).
At the same time, Blake shared Dante's distrust of materialism and the corruptive nature of power, and clearly relished the opportunity to represent the atmosphere and imagery of Dante's work pictorially. Even as he seemed to be near death, Blake's central preoccupation was his feverish work on the illustrations to Dante's Inferno; he is said to have spent one of the very last shillings he possessed on a pencil to continue sketching.
