They determined that a dictator should be created for the purpose of reviewing the senate, and that he should be one who had been a censor, and was the oldest living of those who had held that office.

They likewise gave orders that Caius Terentius, the consul, should be called home to nominate a dictator; who, leaving his troops in Apulia, returned to Rome with great expedition; and, according to custom, on the following night nominated Marcus Fabius Buteo dictator, for six months, without a master of the horse, in pursuance of the decree of the senate.
23.

He having mounted the rostrum attended by the lictors, declared, that he neither approved of there being two dictators at one time, which had never been done before, nor of his being appointed dictator without a master of the horse; nor of the censorian authority being committed to one person, and to the same person a second time; nor that command should be given to a dictator for six months, unless he was created for active operations.

That he would himself restrain within proper bounds those irregularities which chance, the exigencies of the times, and necessity had occasioned.

For he would not remove any of those whom the censors Flaminius and Aemilius had elected into the senate; but would merely order that their names should be transcribed and read over, that one man might not exercise the power of deciding and determining on the character and morals of a senator; and would so elect in place of deceased members, that one rank should appear to be preferred to another, and not man to man.
