Times change, culture changes and art often does not reflect past cultures accurately. No Western culture lasted as long or was as widespread in ancient history than Rome. (If you’d asked a Byzantine who he was, he would have told you that he’s “Roman”. The word, “Byzantine” came later. Then there was the Holy Roman Empire, which it is said, was neither holy, Roman or a true Empire.
There are things that we find acceptable today that the Romans did not. Sometimes there are good reasons for the variance and sometimes it was just a different culture with very different values.
1. Lavishing affection on pets was considered to be demeaning and while it may have happened, it was clearly not public behavior in Rome.
2. Treating social inferiors as equals was not done. And you didn’t treat your betters as equals either. Society was very stratified and everyone had a place. If you allowed social inferiors to treat you as an equal, you’d lose your status.
3. Neither men nor women wore underwear. It was considered to be unmanly/unwomanly to do that.
4. Humility was not a virtue.
5. Revering crucified people, and particularly, worshiping crucified Jews was looked down on.
6. Romans did not kiss on the mouth. It was acceptable to receive a kiss from a non-Roman citizen (a slave or a slave/whore), but it was demoting for citizens to kiss, even to kiss their children.
7. The same was true of oral sex (see 6 above).
8. Romans put fermented fish sauce on everything. I’ve only personally seen that in Asia, but in Rome, it was the rule, not the exception. The lack of fermented fish sauce supplied to legions in the field was believed by legionnaires as a crisis.
I wonder what our ancestors will think of our culture. One thing is certain, they will think the people of 2020 to be insane when they watch old CNN broadcasting.
