I hadn’t read post 35, so why would I have responded to it?
Having read it, at this point, I think it’s a stupid question.
I think it is quite likely that no Pope has ever actually met an Islamic Queen before. Most Islamic Monarchs would not let their Queen meet the Pope - many would not let them meet any man.
But Popes have met other Queens and bowed to them - Pope John Paul II bowed to Queen Elizabeth II on their official meeting in 1980.
Popes have bowed to Queens before. And in diplomacy, religion is not treated as a relevant factor.
For a professional historian and diplomatic officer as you claim to be, you sure don’t evidence it in your posts.
That explains why you can’t respond usefully to post 35.
