A quaestor ( , ; ; "investigator") was a public official in ancient Rome. There were various types of quaestors, with the title used to describe greatly different offices at different times.
In the Roman Republic, quaestors were elected officials who supervised the state treasury and conducted audits. When assigned to provincial governors, the duties were mainly administrative and logistical, but also could expand to encompass military leadership and command. It was the lowest ranking position in the (course of offices); by the first century BC, one had to have been quaestor to be eligible for any other posts.
In the Roman Empire, the position initially remained as assistants to the magistrates with financial duties in the provinces, but over time, it faded away in the face of the expanding imperial bureaucracy. A position with a similar name (the ) emerged during the Constantinian period with judicial responsibilities.
Etymology Quaestor derives from the Latin verb , , meaning "to inquire" (probably ultimately from the Proto-Indo-European root of interrogative pronouns *kʷo-). The job title has traditionally been understood as deriving from the original investigative function of the .
Under the kings
The earliest quaestors were , chosen to investigate capital crimes, and may have been appointed as needed rather than holding a permanent position. Under the Republic, these quaestores parricidii persisted, as prosecutors for capital cases in trials before the people. They disappear, however, by the second century BC.
Ancient authors disagree on the exact manner of selection for this office as well as on its chronology, with some dating it to the mythical reign of Romulus. This view, however, is "not at all credible" and there is no clear evidence for a specific date for the quaestorship's beginning.
During the Republic
The classical quaestors with financial responsibilities may be unconnected with the older questores parricidii. However, the debate still continues, but has more recently trended against connecting the two offices, which are connected by nothing other than a name. The two general theses are that the classical quaestorship related with financial matters either was created entirely separately from the older judicial quaestorship or that it evolved from that older quaestorship to meet greater administrative needs.
The traditional cursus honorum (career path) was loosely regulated, but after 197 BC, became more so, with a basic progression that one first had to hold the quaestorship before being considered for higher office as praetor or consul, with quaestor as the lowest office. After Sulla's reforms, the cursus honorum was cemented, with the added requirement that to stand for the quaestorship, one first needed to have been one of the vigintiviri and have held the military tribunate. The reforms also established that the minimum age for candidates had to be 30.
Quaestors were elected last in the electoral comitia, as they were of the lowest rank. During the late Republic, however, their terms of office started before their more senior colleagues, on 5 December rather than 1 January. This was the earliest term start of the major magistracies of the Republic, being earlier than that of the tribunes of the plebs (who came into office on 10 December).
Responsibilities
After election, they were assigned – usually by lot on their first day in office – to their tasks. Very rarely were quaestors directly assigned to a specific task without lot (i.e., extra sortem), likely with the approval of the senate to a magistrate's request. Some quaestors were assigned to specific tasks (the management of the treasury or of the grain supply in Ostia), but most were assigned to assist a higher magistrate.
Those assigned to the treasury were supervised by the Senate (usually with the consuls as intermediaries), while those assigned to a higher magistrate were supervised by their superior. Quaestors could be dismissed by their superiors, but this appears rare; there is only one known case thereof, when then-proconsul Marcus Aurelius Cotta dismissed his quaestor Publius Oppius in 73 BC.
In the early Republic, one quaestor was attached to each consul, both when the consul was in Rome for civic duties and on military campaign. By 227 BC, every magistrate with imperium (consuls and praetors) left the city accompanied by a quaestor. This close cooperation led these provincial quaestors to take a more active role in assisting their superiors with military – even assuming command at times – and administrative tasks. The expanding use of prorogation also affected quaestors, who were regularly prorogued with their superiors pro quaestore; more frustratingly, ancient sources did not always differentiate between quaestors and their proquaestorian counterparts, regularly calling both quaestors.
Quaestors in the provinces generally remained in the same province as their superiors for the duration of the superior's term, but this was not obligatory, as the quaestorian careers of Gaius Gracchus, Julius Caesar, and the rotating names of quaestors serving under Gaius Verres attest. Terms in the provinces usually lasted one or two years. Quaestors acted militarily solely under the auspices and imperium of their commanders, except under exceptional circumstances such as the death of that commander.
The relationship between a governor and his quaestor was similar to that between a patron and a client, but was entirely official. While in office together, a quaestor was expected to show "reverence, courtesy, and loyalty" to his governor; the governor was likewise obliged to respect his subordinates. This relationship often continued past the designated terms of either individual, and the quaestor could be called upon for assistance or other needs by the consul. Also related were the need to maintain a working relationship to avoid tensions that could endanger the province, as well as a "certain degree of complicity [needed...] to conceal anything that could compromise the magistrates' reputations".
Domestic duties
There were usually two quaestors assigned to the city of Rome (termed urban quaestors), with both simultaneously responsible for the treasury. While some older scholars believed that the urban quaestors were forbidden from leaving the city, this is now rejected.
The normal main duty of the urban quaestors was to handle the aerarium (the public treasury). This involved control and management of the gold and coins stored there, safekeeping of the keys to the treasury, supervision of all public expenses and tax receipts, validation of official documents, and archival of the same. The quaestors were aided by assistants called apparitores, who likely served multi-year terms to familiarise themselves with the job; their number multiplied during the later Republic to meet administrative needs. As part of administering the treasury, they also handled the receipt and auditing of war reparations and tribute from polities defeated by Rome. Collections of taxes were also handled by the urban quaestors and their staff, with overpayments reimbursed when funds became available. They also made the appropriate withdrawals from the treasury to cover various expenses – including building, army pay, temple maintenance, state visits, state funerals, road maintenance, minting of coins, etc – as directed by the Senate.
They were also in charge of auctions for public land (ager publicus). Such land was acquired by conquest and became the property of the Roman people. Land sales could be directed by the Senate to meet funding shortfalls, as during the Second Punic War, when the urban quaestors auctioned lands around Capua to raise funds. These quaestors were also responsible for handling public auction of war booty returned to the public treasury by victorious generals. This included objects as well as slaves, with the proceeds to be deposited in the public treasury. They were also responsible for public auction of property seized from citizens who had debts or fines owed to the state if they were unable to pay. These responsibilities over public debts also included the collection of fines in general, where a convict ordered to pay a fine would be required to make a surety to the urban quaestors and deposit the money in the aerarium.
Returning magistrates and governors also had to produce detailed account books for their handling of public money, which would then be deposited in the treasury, where the urban quaestors and their staff would audit them. These records were supposed to total a running ledger of starting balances, a line-by-line itemised accounting of all inflows and outflows, and ending balances for the province. They also included, for generals, detailed lists of all the money, gold, silver, spoils, and other assets acquired during a governorship., citing Cic. Verr., 2.1.57: "You see not only the number of the statues, but the size, form, and the state of each one accurately put down in writing". The scribes checked the account books, looking for transactional documentation and arithmetic errors, the results were then approved or disapproved by the quaestors. A negative audit could provide fodder for corruption charges, which was regular in the last two centuries of the Republic.
After the formation of the permanent courts (), the urban quaestors were also responsible for assembling the jury pools and allocation of portions of those pools to the various courts. These quaestors also handled various tasks assigned ad hoc by the Senate, such as meeting and accompanying foreign dignitaries on state visits or leaving Rome to the provinces on special assignments. (describing an urban quaestor leaving the city to bring money to Gaius Marius during the Jugurthine War).
In the earlier Republic, the quaestors also controlled the distribution of the legionary aquilae (eagle standards), which were kept in the treasury before distribution to generals before they were returned on the conclusion of a campaign. This likely, however, fell into disuse as Rome expanded across the Mediterranean.
Provincial administration
Because consuls, praetors, and their promagisterial counterparts were "practically... plenipotentiary agent[s] upon [which all] aspect[s] of government associated with that provincia depended", the quaestor's responsibilities could vary widely, including not only financial and administrative matters but also sometimes encompassing military command and judicial functions. In general, however, the core administrative duty of the quaestor was to "[extract] whatever material assets the Roman military apparatus might need". When quaestors were sometimes assigned to a province alone (without attachment to a superior) in the late republic, quaestorian responsibilities increased dramatically as the only Roman magistrate present. At times, quaestors were sent without superiors to peaceful acquisitions to inventory property, auction them if necessary, and transport proceeds to Rome.
During normal times under a governor, the quaestor would handle administrative tasks related to supply of the armies. He would oversee the transport of public money assigned by the Senate to the province, record its uses, and use it to pay soldiers' wages or purchase supplies. He also helped manage the taxation of the province in terms of collecting food, supplies, and money from local leaders. In terms of taxation, quaestors also handled the local auction of raw goods to public contractors (publicani) or merchants; at times, they also made requisitions from local provincials on orders of their superior or at times on their own accord. This remit also extended to minting coinage – usually to pay soldiers serving in the provinces – from precious metal stocks on hand.
