A new study claims that renowned Welsh poet Dylan Thomas (1914-1953), one of the most influential voices in 20th-century English poetry, plagiarized several texts during his adolescence. The research, published in the British literary journal The Times Literary Supplement, was conducted by Italian editor and translator Alessandro Gallenzi. He identified at least a dozen poems that are alleged to have been copied by Thomas while he was a student at Swansea Grammar School. According to the study, these texts appeared in both the school magazine and the local newspaper The Herald of Wales between the late 1920s and early 1930s. Gallenzi states that the poems did not merely show recognizable influences but were copied almost entirely from works by other contemporary authors. In some cases, Thomas reportedly changed titles or substituted individual words, 'probably to avoid detection,' the researcher suggests. The editor, who describes himself as 'a lifelong admirer of Thomas and his poetry,' asserts that the findings reveal 'a chain of brazen thefts that stretched for at least four years,' during the poet's formative period, prior to the publication of his mature works. Gallenzi has announced that he will include the disputed poems in an upcoming critical edition of Dylan Thomas's poetic works, to be published by his London-based press, Alma Books, in February.
