“…Turning from technology to metacognition, Dietrich Bitterli discusses the riddles' metacognitive and metatextual play, their invitation "to think about the very act of riddle-making and riddle-solving, of writing and reading" (Bitterli 2009, Chapter 7, "Silent Speech," 135-150). (For other reflections on the materiality and metatextuality of the riddles, see Shook 1974, Lerer 1991, Bitterli 2009, Symons 2017, and Weaver 2019.) §29 Jessica J. Lockhart sees another one of the writing technology riddles, the Bookmoth riddle, in its meditation on books, reading, and memory, as "a model of reception for the [riddle] tradition as a whole" (Lockhart 2017, 133-135).…”
