Endless bits of wisdom from canonical writers have come down to us as Latin dicta: a sort of Ancient proverbs, if you will, with the notable exception that these were, unlike modern, post-Antiquity proverbs, written by an identifiable writer, not said by an anonymous and heterogeneous source.
So my question is simple: were there in Latin proverbs like the modern ones, the creations, over centuries, of anonymous people, always in autonomous contexts, and not part of larger writings, from which they were taken out as dicta standing, somewhat anachronistically, on their own?
