Thoughts about the lack of sky in Roman art

[meisenimverbis]

It's difficult to find depictions of the sky, clouds, smoke, landscape, mountains, lakes, stars in Roman art. Only sun and moon are there.

I guess, in a way, it might be related to the fact that they personified everything... (Winds, the sky (Uranus), day, night, nature (Flora).)

Any thoughts?
