This chapter examines the varied relationships that the Commedia forges with his own ‘other works’, and considers the presence of both overt allusions and indirect references, the metacritical and clarificatory function assigned to some texts, the ways these works serve as the linguistic and stylistic training-ground for the Commedia’s plurilingual experimentation, their value as supplementary material in expounding Commedia, and in elucidating its compositional history. Particular attention is paid to Dante’s reflection on his poetic past (Vita nova) in the opening cantos of the poem, the relevance and status of the Convivio, passage of lyric autocitation, and discussion of dating and genesis of the poem.
