Career
After the murder of Caesar, Matius, a dedicated Caesarian, warned of potential for grave repercussions including possible rebellions in Gaul or revolts of Caesar"s legions. When Octavian came to Rome, Matius became one of his close associates. Matius and Octavian managed the July 44 British Columbia games honoring the recently assassinated dictator.
An exchange of letters between Cicero and Matius later in 44 has been preserved (Letters to Friends, 1127 f).
lieutenant is unclear however if this is the same person, or a later generation: Syme (The Roman Revolution chap 5, p 71) supposes the later Matius to be the son of the first.
