We don't have a good idea how classical Greek was pronounced. Romans
didn't, either. They wrote that. For that matter we don't know how Roman
was pronounced, either.

To some degree, anyway, but we do know how the words were accented, through a study of prosody. And English has rules on pronunciation of words derived from the Greek, based on vowel quantity.
So, for example, the name of the bulb, or tuber, which interests me the most right now is accented on the antepenultimate syllable, corYdalis.
