[2] : Bouvier's Law Dictionary, Revised 6th Ed (1856)

questor or quaestor, civil law. a name which was given to two distinct 
classes of roman officers. one of which was called quaestores classici, and 
the other quaestores parricidii, 
     2. the quaestores classici were officers entrusted with the care of the 
public money. their duties consisted in making the necessary payments from 
the aerarium, and receiving the public revenues. of both, they had to keep 
correct accounts in their tabulae publicae. demands which any one might have 
on the aerarium, and outstanding debts were likewise registered by them. 
fines to be paid to the public treasury were registered and exacted by them. 
they were likewise to provide proper accommodations for foreign ambassadors 
and such persons as were connected with the republic by ties of public 
hospitality. lastly, they were charged with the care of the burials and 
monuments of distinguished men, the expenses for which had been decreed by 
the senate to be paid, by the treasury. their number at first was confined 
to two, but this was afterwards increased as the empire became, extended. 
there were questors of cities, provinces, and questors of the army, the 
latter were in fact pay-masters. 
     3. the questores parricidii were public accusers, two in number, who 
conducted the accusation of persons guilty of murder or any other capital 
offence, and carried the sentence into execution. they ceased to be 
appointed at an early period, smith's dic. gr. and rom. antiq. h.v.
