Quadruplātor
A professional accuser in those cases under the Roman law which involved a pecuniary
penalty (
Verr. ii. 8.22). The name probably owes its origin to the fact that
the quadruplator professed to expose offences in which the fine was fixed at four times the
damage, as, for example, a violation of the usury laws (
Livy, vii.
28), and in which, therefore, his own reward would be large. See Geib,
Criminalprocess, 106; and the article Delator.
