Could still have a firmament if the earth's round. I think rainbows might be the shape of the firmament.
Yeah I know that, I was talking about around the Earth, 7 Colors of the rainbow for 7 heavens?
The firmament in that painting is the same shape as rainbows.
well the one in the painting is blocked by the ground
Rainbows need 2 lens to pass through to become rainbows, the water is only 1 lens, firmament the other?
