What punctuation was used in Classical Latin? was very insightful, but it doesn't go into specifics. Wikipedia said we don't have any original sources of Ovid's Metamorphoses until the 9th or 10th centuries. How did they first write down Metamorphoses at that time (9th, 10th, 11th centuries, etc.)? And how did Ovid most likely write it down? Or would it have been entirely oral?
Related to this, I am wondering how it was formatted/punctuated. Did it or would it have used all capital letters? Would it use whitespace between words or interpuncts of some kind. Again, most likely as we probably don't have much direct evidence, but who knows. Was it really divided into lines like you find it today? Or was it just one long mass of text? Did sentences have boundaries? Were there actually books, or was that a more modern invention (i.e. was it just one big block of text)?
