Yet Suetonius names Brutus as Decimus Brutus. Is this a different Brutus, a cousin? Is that what you mean?
“More than sixty conspirators banded together against him, led by Gaius Cassius and Marcus and DECIMUS BRUTUS.”
He means Marcus Brutus and Decimus Brutus, two different people. Sorry, I should have included that link, I must have forgotten it, I had it open and planned to paste it. :’)
IOW, what VR said. :’)
