Tribūni Aerarii
The name given among the Romans in earlier times to the wealthy members of the several
tribes who were intrusted with the levying of the war-tax (see
Tributum) and the distribution of pay to the soldiers from the proceeds
of it. What position they held after the payment of the troops was handed over to the
quaestors is not clear, from want of information on the subject. In the first century B.C.
they appear as a distinct class, from which, during the years B.C. 70-46, the third
decuria of judges was appointed to represent the plebeians, the other two
consisting of senators and knights.
