Cool! And interesting. The world obviously doesn't quite agree on the Roman gods... Some of the publications on the subject place them quite calmly on Olympus, the mountain of the Greek gods. The other part does not grant them a kind of residence; there the deities are manifested in the elements and natural phenomena. The latter reading is more sympathetic to me, as it does not take as its starting point all-dominant figures, but rather the sublimity in everything around us...
So much has been said about Jupiter before, (both the planet and the divinity), that it is probably futile to try to walk that street. I just looked for a relatable, everyday experience from a long, long time ago. It's easier, for me, to talk about human things than about godly things.
The core problem of all religions, I guess ;-))
