Defeated by Spartacus (Liv. Per. 96). Both he and Arrius (7) are termed praetor in Liv. Per. 96. Arrius as the intended successor to Verres probably held the praetorship in 73 and was a promagistrate in 72. For Manlius we have no such evidence, but his career may be parallel, since the praetors had charge of the courts in Rome. He is listed in MRR (2.116) at the latest possible date, but 73 may be more probable. (Broughton MRR III)
