nate might receive an added augmentation from the numbers of that order, he filled up the list of the Fathers, which had been abridged by the late king's butcheries, drawing upon the foremost men of equestrian rank until he had brought the total up to three hundred.
From that time, it is said, was handed down the custom of summoning to the senate the Fathers and the Enrolled, the latter being the designation of the new senators, who were appointed.Later any senator might be called pater conscriptus, and it is possible that Livy and Festus (p. 254 M) were misled in supposing that originally the patres were one class of senators and the conscripti another. See Conway's note. This measure was wonderfully effective in promoting harmony in the state and attaching the plebs to the Fathers.Livy appears to have assumed that the new senators were plebeians, but this is almost certainly wrong. The first definite notice of a plebeian senator occurs at v. xii. 11 (400 B.C.).
