Lucius Junius Brutus
Geoffrey Bullough argues that Lucius' character arc (estrangement from his father, followed by banishment, followed by a glorious return to avenge his family honour) was probably based on Plutarch's "Life of Coriolanus". As for Lucius' name, Frances Yates speculates that he may be named after Saint Lucius, who introduced Christianity into Britain. On the other hand, Jonathan Bate hypothesises that Lucius could be named after Lucius Junius Brutus, founder of the Roman Republic, arguing that "the man who led the people in their uprising was Lucius Junius Brutus. This is the role that Lucius fulfills in the play."
