actually the part that i am scratching my head at is the sevenfold brighter bit.

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 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^7 not n*7.
