Romans were clean shaven. Greeks sported beards.
In most cultures, a beard is a symbol of being a man and all that goes with it.
Such as Islam?
And the bearded Greeks became the clean-shaven Romans’ bitches.
“Mr. Whiskers”? No thanks! Not for me.
Shaving cream, feel nice and clean.
Shave every morning and always be keen.
Not really true as a definitive statement. Beards came and went in both societies over the roughly 1000 year period we think of as "classical."
Both societies originally were bearded, of course.
Alexander the Great made shaving popular among Greeks, Scipio Africanus among Romans. Hadrian brought beards back in Rome, but they went out again with Constantine till well after Justinian.
The moral of the story being that it's really difficult to make broad statements about societies over a period of 1000 years plus.
I can't count how many gay men I've seen who have facial hair starting under their noses and closing on the chin. It strikes me as vaginal hair. Symbol of being a man?
