Factual error: Cicero's secretary, Tiro, is seen throughout the series wearing a plaque around his neck marking him as a slave, and here Cicero tells him, "You've been freed in my will". However, Tiro was freed in 53 BC, several years before the events depicted in the series.

1 factual error in Philippi
Starring: Polly Walker, Ray Stevenson, Kevin McKidd, Kerry Condon
Factual error: The verse Octavia recites is from Virgilius' poem "the Aeneid". That poem was written at least a quarter of a decade after the death of Caesar.
Cassius: Look now. Look at that.
Marcus Junius Brutus: It is a chair. What of it?
Cassius: A chair? It's a throne.
Marcus Junius Brutus: I believe thrones are generally more decorative. That is decidedly plain, and chair-like.
Trivia: Pompey Magnus had two sons that fought against Caesar: Cnaeus and Sextus. He never had a son named Quintus as is stated in the series.
Question: Who is the mother of Pompey's children? His new wife can't be their mother, since they are too old compared to Niobe's son who's an infant when the show starts. And they can't be Julia's children, since Pompey is worried Caesar might kill them, and Caesar wouldn't murder his own grandchildren.
Answer: According to wikipedia, Pompey's children are all from his third wife, Mucia Tertia. Julia is his fourth wife. See: http://en.wikipedia.org/wiki/Pompey#Marriages_and_offspring.
