Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
While
formerly the commander-in-chief of the one year had reckoned it an
honour to serve next year on the staff of his successor, the fact that
the consular Cato took service as a military tribune under Tiberius
Sempronius Longus (560) and Manius Glabrio (563;(47)), was now
regarded as a demonstration against the new-fashioned arrogance.
Formerly the thanks of the community once for all had sufficed for
service rendered to the state: now every meritorious act seemed to
demand a permanent distinction. Already Gaius Duilius, the victor of
Mylae (494), had gained an exceptional permission that, when he walked
in the evening through the streets of the capital, he should be
preceded by a torch-bearer and a piper. Statues and monuments, very
often erected at the expense of the person whom they purported to
honour, became so common, that it was ironically pronounced a
distinction to have none. But such merely personal honours did not
long suffice.
