The word "pandemonium" was coined by the English author John Milton and published in his 1667 story Paradise Lost
, where the center of hell is called "Pandaemonium." The word is derived from the Greek "pan," meaning "hell," and daimon, meaning "demon."
This sinister etymology drew Killing Joke lead singer Jaz Coleman to the word, which has a sound an meaning that intrigued him. "We were getting really into the chaos theory, and it was the beginning of the multiverse, and discussing wonderful ideas like this," he said in his Songfacts interview
. "And of course, we met lots of scientists and thinkers at that time."
