In 1939, Keidrych Rhys charged that Dylan Thomas’ “Prologue to an Adventure” was reprinted “in Delta (Paris) without acknowledgement… without permission”; however, Ralph Maud contrarily argues “Durrell, as editor of Delta, asked Thomas for contributions and published something by him in all three issues” (123). Thomas’ letters support the latter position and suggest he returned to the story for Delta, aiming for publication in a book project through the Obelisk Press in Paris. Hence, this later printing indicates his final intentions. This challenges the authoritative editions of Thomas, works, and I argue for a corrected edition of “Prologue to an Adventure” based on the Delta printing.
