I read online (I'm sorry, I can't remember where) that if two adjectives refer to the same noun, you have to use a conjunction like "et" or "-que".
Socrates sapiens senex vir est. (incorrect)
Socrates sapiens senexque vir est. (correct)
Is this true? If so, is it only classical or in all Latin styles?
I remember reading "integrum inlaesum" in a letter by Pline.
