Before we get to the film, take another look at the passage and sum up what you know.
It is a piece of autobiographical prose, partly about the author’s father. It deals will legal matters and exile, probably in the Roman Republic (you’ll have spotted rei publicae). If you remember veni, vidi, vici, you’ll know that some conquering has been done. Vici means “I conquered,” so we can assume that it is Augustus himself claiming victory in a conflict of some kind.
This is a great start. Let’s power on ahead and learn the vocabulary.
