The forthcoming book Speculative Poetry and the Modern Alliterative Revival: A Critical Anthology (December 2023) may interest some readers…

If a literary movement arises but no one notices, is it still a movement? […] this anthology collects for the first time over fifty speculative poets. […] Alongside such established names as C.S. Lewis, Patrick Rothfuss, Edwin Morgan, Poul Anderson, Jo Walton, P.K. Page, and W.H. Auden, this anthology also includes representative texts from cultural movements such as contemporary neo-paganism and the Society for Creative Anachronism.

No mention of Tolkien, but I guess it may have been difficult or expensive to get the Tolkien Estate’s permission to reprint?
