”This heart is sore and sad. Crossed in love?”The manuscript of ‘Giacomo Joyce’, written in James Joyce’s best handwriting and folded between the covers of a school notebook, was discovered in Trieste. Most likely written in 1914, some of it served as a rehearsal for passages in `Ulysses`. Had Joyce meant to pillage it or publish it? Either way, this fragmented evocation of unrequited desire is, in the words of Joyce’s biographer Richard Ellmann, a work of ‘small, fragile, enduring perfection’.With a new introduction by Colm Tóibín.
