I was curious about this too. From random web searching (Syfy.com), the sun is 200,000 times brighter than the moon in the visible light region of the electromagnetic spectrum.
I didn’t know about logarithmic perception, that’s interesting! I bet you’re right about 7x being chosen due to the significance of the number seven in the Bible.
actually the part that i am scratching my head at is the sevenfold brighter bit.

I know human perception is logarithmic. I’m interested why it was thought it was 7x brighter. “Sevenfold as the seven days in one” it seems?
I think sevenfold means
n^7notn*7.https://en.m.wiktionary.org/wiki/sevenfold
n*7
