some plebeians were chosen--the first non-patrician magistrates that
the Roman community had.

Taking a connected view of these measures, we can scarcely attribute
to them any other design than that of substituting for tribunician
intercession a limitation of the consular powers by written law.
On both sides there must have been a conviction that things could not
remain as they were, and the perpetuation of anarchy, while it ruined
the commonwealth, was in reality of no benefit to any one. People in
earnest could not but discern that the interference of the tribunes
in administration and their action as prosecutors had an absolutely
pernicious effect; and the only real gain which the tribunate brought
to the plebeians was the protection which it afforded against a
partial administration of justice, by operating as a sort of court
of cassation to check the caprice of the magistrate. Beyond doubt,
when the plebeians desired a written code, the patricians replied that
in that event the legal protection of tribunes would be superfluous;
and upon this there appears to have been concession by both sides.
Perhaps there was never anything definitely expressed as to what
was to be done after the drawing up of the code; but that the plebs
definitely renounced the tribunate is not to be doubted, since it was
brought by the decemvirate into such a position that it could not get
back the tribunate otherwise than by illegal means. The promise given
to the plebs that its sworn liberties should not be touched, may be
referred to the rights of the plebeians independent of the tribunate,
such as the -provocatio- and the possession of the Aventine. The
intention seems to have been that the decemvirs should, on their
retiring, propose to the people to re-elect the consuls who should
now judge no longer according to their arbitrary pleasure but
according to written law.
