Isn’t the legend that anyone who went up to the Maharl’s shul’s attic, where the Golem remained after the Maharal was niftar, came back down insane. They therefore locked the door, and everyone was afraid to go up.
As a kid I read the book “The Golem of Prague” by Gershon Winkler. I remember really enjoying it.
I had a Rebbe, an adam gadol, who in shiur said over something from the Maharal’s sefer on Mesechta Shabbos (regular “Achron” style chiddushim on Gemara, Rashi & Toisfois.) He looked up and said straight faced, when the Maharal wasn’t making Golem’s he wrote chiddushim on Mesechte Shabbos.
