The terminology for upper and lower case didn't even exist before the printing press was reinvented in Europe
Clearly that terminology didn't exist, since that derives from the boxes printers kept their type in. However the concept did, as can clearly be seen here: http://downloads.bbc.co.uk/rmh... Perhaps you're thinking of the Romans?
I never saw much sense in mixing majuscule and minuscule scripts to denote proper nouns or the start of a sentence.
I never saw much sense in referring to things that don't pee, either standing or sitting, as "he" or "she". But I doubt the French and Italians will invent a neuter gender for my convenience.
