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 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.
