Who was Decidius Saxa?

The world of learning owes debts many and varied to Sir Henry Stuart Jones: it is the Camden Professor and historian of Rome that Oxford knows best. In Roman history, wherever knowledge may be deepened and however horizons may be widened, the transformation of the Roman State and the transition from Republic to Principate must ever claim the centre of interest. For this reason a paper concerning one of Caesar's partisans, a military man from Spain, may be offered as a tribute from the School of Literae Humaniores—and from one of the three Colleges with which Sir Henry's life in Oxford has been identified.
