The 1940 Under the Volcano—hidden for too long in the shadows of Lowry’s 1947 masterpiece—differs from the latter in significant ways. It is a bridge between Lowry’s 1930s fiction (especially In Ballast to the White Sea) and the 1947 Under the Volcano itself. Joining the recently published Swinging the Maelstrom and In Ballast to the White Sea, The 1940 Under the Volcano takes its rightful place as part of Lowry’s exciting 1930s/early-40s trilogy. Scholars have only recently begun to pay systematic attention to convergences and divergences between this earlier work and the 1947 version. Miguel Mota and Paul Tiessen’s insightful introduction, together with extensive annotations by Chris Ackerley and David Large, reveal the depth and breadth of Lowry’s complex vision for his work. This critical edition fleshes out our sense of the enormous achievement by this twentieth-century modernist. Published in English.
