Add to this
the personal impression, which most of these Peloponnesian statesmen
produced in Rome; even Flamininus shook his head, when one of them
showed him on the one day how to perform some dance, and on the next
entertained him with affairs of state. Matters went so far, that the
senate at last lost patience and informed the Peloponnesians that it
would no longer listen to them, and that they might do what they chose
(572).
This was natural enough, but it was not right; situated as
the Romans were, they were under a moral and political obligation
earnestly and steadfastly to rectify this melancholy state of things.
Callicrates the Achaean, who went to the senate in 575 to enlighten
it as to the state of matters in the Peloponnesus and to demand a
consistent and calm intervention, may have had somewhat less worth as
a man than his countryman Philopoemen who was the main founder of that
patriotic policy; but he was in the right.
