The January issue of Harper's contains an article on the late Pablo Neruda, by Emily Witt.
My own highly selective take away from the article is its reference to a plagiarism scandal I had never heard of. Apparently, "Poem 16" of Neruda's work, "Twenty Love Poems and a Song of Despair" are "lifted almost verbatim from the Indian poet Rabindranath Tagore," Witt says. There was apparently quite a fuss over this back in the 1930s.
Twenty Love Poems, published in 1924, is the work that made Neruda famous. So I gather the plagiarism too a few years coming to light.
I've only vaguely heard of Tagore. But I've given you his image above, thanks to the wonders of googling.
I think I should look into this matter some more.
