I've heard about the famous
nutter occultist, religion founder, and writer Aleister Crowley since my childhood, but always pronouncing it to rhyme with "owly". For this reason, when reading Good Omens I also pronounced the demon Crowley's name that way in my head, and I was surprised to find it rhyming with "holy" "unholy" in the TV adaptation. Then, doubting myself on the pronunciation of the original Crowley, I went to check online and found that Wikipedia says Aleister Crowley's name also rhymes with "unholy". But this claim on Wikipedia is unsourced.
How did Aleister Crowley pronounce his last name? Is there any evidence in his writings?
