I think it’s interesting how the africans in Egypt came before the Greeks and Romans discovered all the planets which is well documented by them but some Greeks and Romans and modern technology get the credit for it lol the cadeuces for example is not Roman/Greek this was used by the Egyptian god Thoth who planet was mercury in which he was the god of knowledge, writing, science, literature, mathematics, etc. this is a little misinformation but I guess if you are studying what the Greeks did not understand themselves in which the Roman later conquered and did not understand what the Romans didn’t then shit gets messy lol
For the symbol of Jupiter I actually found a lot of different explanations. Some say it's a modified version of the Greek Z, some say it's an eagle seen in profile, still others a hand holding a lightning bolt
