This thesis considers the imbrications created by James Joyce in his writing with the work of John Milton, through allusions, references and verbal echoes. These imbrications are analysed in light of the concept of 'presence', based on theories of intertextuality variously proposed by John Shawcross, Hans Ulrich Gumbrecht, and Eelco Runia. My analysis also deploys Gumbrecht's concept of stimmung in order to explain how Joyce incorporates a Miltonic 'atmosphere' that pervades and enriches his characters and plot. By using a chronological approach, I show the subtlety of Milton's presence in Joyce's writing and Joyce's strategy of weaving it into the 'fabric' of his works, from slight verbal echoes in Joyce's early collection of poems, Chamber Music, to a culminating mass of Miltonic references and allusions in the multilingual Finnegans Wake.
