Were they spoken at all or were they just used for writing?
Homeric Greek was sung before written. Classical Latin was certainly spoken, but just not the language of the common people.
Personally, I try to use 'me' as an objective pronoun only, but I understand what you are saying. I guess there will always be a discontinuity between the spoken vernaculars and their written counterparts. What becomes of modern languages with standard bodies dedicated to preserving their structure? Do they possess this same disconnect?
I believe so, if recent observations are to be trusted. It's a slow process, however.
