or Questor, in Roman antiquity, an officer who had the management of the public treasure.

The questorship was the first office any person could bear in the commonwealth, and have a right to sit in the senate.

At first there were only two; but afterwards two others were created, to take care of the payment of the armies abroad, of selling the plunder, booty, &c. for which purpose they generally accompanied the consuls in their expeditions; on which account they were called peregrini; as the first and principal two were called urbani.

The number of questors was afterwards greatly increased. They had the keeping of the decrees of the senate: and hence came the two offices of questor principis, or augusti, sometimes called candidatus principis; whose office resembled in most respects that of our secretaries of state, and the questor palatii, answering in a great measure to our lord-chancellor.
