Google: Daedalus nightmare history. Just those three words, and you shouldn’t need to put quotations round them. Be careful with the spelling of Daedalus (you can also use “Dedalus,” which is actually the correct spelling of the name in Ulysses, but you’ll get a better result with “Daedalus”).
You should get a clear and obvious result. What is it? How can it be applied, not only to the Joyce stories that you’ve been reading (I hope), but perhaps also to Mrs D and to the early 20th century, and … well, heck, now?
