In an earlier volume of these Papers (xxxii, 1964), I tried to challenge a theory put forward by the late Professor Degrassi, that P. Popillius Laenas, cos. 132 B.C., began the building of two roads in his consulship—from Capua to Rhegium and from Ariminum to Aquileia—and that this programme was taken over and completed the following year by the praetor T. Annius T.f. My arguments have met with some opposition, and it is perhaps time to see to what extent they still stand up. Section I of what follows deals with the roads to Aquileia, section II with that to Rhegium.
