Early days

Timesitheus' career before his appointment as Praetorian Prefect is recorded on an inscription on a statue from Lugdunum in the province of Gallia Lugdunensis (Lyons, France).^[8]

Late in the reign of Septimius Severus, or during the reign of Caracalla, Timesitheus was Prefect of Cohors I Gallicae in the province of Hispania Tarraconensis (Mediterranean Spain). This appointment was a typical first step for an equestrian seeking a career in the imperial service under the so-called Tres militiae system. Under that system Timesitheus might have been expected to go on to two additional junior military prefectures, firstly of a legionary cohort and then of an ala (Roman cavalry unit). Only then would most aspiring equestrian functionaries have been considered eligible for appointment as a procurator (financial administrator), the usual first step to high office in the Equestrian Service. However, Timesitheus seems to have missed out these two stages in the equestrian cursus and is next recorded as the Procurator Rationis Privatae (superintendent of the private properties of the Imperial Family) in the provinces of Belgica (north-east Gaul),Germania Inferior (the northern section of the Roman-controlled Rhineland) and Germania Superior (the southern section of the Roman Rhineland).^{[lower-alpha 6]} He probably held this office under Caracalla.^{[lower-alpha 7]} This position carried the equestrian rank of sexagenarius, indicating that he had thus became a member of that class of equestrian functionaries who were paid a nominal salary of 60,000ss/annum.^{[lower-alpha 8]}

His next recorded appointment was as Procurator provinciae Arabiae (financial administrator of the province of Arabia Petraea). With this posting Timesitheus became a centenarius (nominal salary 100,000ss/annum). In addition to his procuratorship he also served on two occasions (218 and 222 AD)^[10]) as vice praeses of the province - i.e., he acted as its governor (in place of a senatorial legatus). In this capacity he would have commanded Legio III Cyrenaica.^{[lower-alpha 9]} Timesitheus was en poste as acting-governor in 222 AD and may have played a part in the overthrow of the equestrian usurper Marcus Opellius Macrinus in favour of Elagabalus.^[11] This service to the Severan dynasty might explain his continued rise under the regime of the "Syrian Princesses" who would certainly have been responsible for his appointment as Procurator in urbe Magister XX heredatium (collector of the one-twentieth - 5% - tax on inheritances in Rome), a post conferring ducenarius rank (salary 200.000ss/annum), and, at the same time, Logista Thymelae (Superintendent of the Imperial Theatre Properties).^[12] The office of Magister XX heredatium was an important financial post requiring expert administration. However, as holder of that office and that of logista Timesitheus also became a member of the court-circle. That may well have been the main object of the Syrian Princesses in securing him these appointments - to move a man who had proved his loyalty to them into a position where he would be able to exert influence on their behalf in areas well beyond the limits of the job-descriptions pertaining to his specific offices. As far as Timesitheus's career was concerned, his access to Imperial patronage as a palatinus, or courtier, would have effectively set him above less-favoured ducenarii officials in the competition for procuratorial postings; there followed two important appointments which were associated with the two major wars fought by Alexander Severus, first against the renascent Persian Empire (232 AD)^{[lower-alpha 10]} and then against the league of German Peoples who were to become known to the Romans as the Alemanni (234-5 AD)^{[lower-alpha 11]} in which Timesitheus's assorted military and procuratorial competencies would, perhaps, have been particularly useful to the regime.

The first of these appointments was as Procurator provinciae Syriae Palaestinae ibi Exactor Reliquorum Annonae Sacrae Expeditionis (Procurator of Syria Palaestina with particular responsibility for collecting the balance of the taxes-in-kind (annonae) levied in support of the "Sacred War;^{[lower-alpha 12]} and then Procurator patrimoni provinciarum Belgica et duarum Germaniarum ibi vice praesidis provinciae Germaniae Inferioris (Administrator of the Imperial Patrimonial Domains, viz., the estates that belonged to the Imperial Office as opposed to the private estates of the Severan Dynasty) in Belgica and the two Germanies (Germania Inferior and Germania Superior). While holding that office he was also made vice praesidis (Acting Governor) of Germania Inferior - the lower Roman Rhineland - in which capacity he commanded the two legions stationed in that province during Alexander Severus's German war. (To make it possible for Timesitheus to be put in command of these legions while retaining his equestrian status was probably the main object of Julia Mammaea in securing him the procuratorial appointment: it provides yet further evidence of the trust she had in him. Whether or not he actually saw action in that abortive conflict with the Alemanni is unknown.) That Timesitheus remained an equestrian when he might well have been adlected to the senate and, thus, been eligible to be appointed as the praetorian legatus of Lower Germany instead of just a vicar - i.e., one who acted on behalf of (vice) such an officer - was probably his choice. It is likely that he had already set his sights on the Praetorian Prefecture which was the most powerful position available to a subject under the Roman polity in the Third Century AD. That object of his ambitions would have been denied him under the prevailing Roman Administrative Law had he become a senator.^[13]

Death of Alexander Severus

The mutiny of the army in Germany that resulted in the murder Alexander Severus and his dominating mother, Julia Avita Mamaea, and their replacement by Maximinus Thrax might have been expected to set back the career of a man who had been so closely associated with the Severan Dynasty and with Mamaea herself. However, not only did Timesitheus survive, but his career continued to prosper. Under the new regime he became Procurator provinciae Bithyniae Ponti Paphlagoniae tam patrimoni quam rationis privatae ibi vice procuratoris XXXX, item vice proco(n)sulis - i.e. fiscal administrator of the Asiatic Black Sea provinces of Bithynia, Pontus, and Paphlagonia with particular responsibility for managing the Imperial domains, both patrimonial and private. In addition, he was made acting procurator responsible for the collection of the custom duties levied at one-fortieth ad valorem. As in his previous posting in Germania he was also appointed acting proconsul - i.e., governor of these provinces - thus replacing a senatorial appointee (this time of consular status) for whom that office would normally have been reserved. Whatever reservations Maximinus Thrax may have entertained regarding Timesitheus's loyalties, his need for money to finance his German wars obviously did not allow him the luxury of foregoing the financial and administrative expertise the man could bring to his government of the Empire. (At the time - viz., before the assaults on this region mounted by barbarians from the lands to the north of the Black Sea and the Sea of Azov that were to characterise the middle years of the Third Century^{[lower-alpha 13]} - the provinces given over to Timesitheus's care were among the richest in the Roman world). However, it may be indicative of the emperor's reservations that, whereas in Germany Timesitheus had commanded two legions, he now had none, Asia consisting of provinciae inermes - i.e., provinces where there were no Imperial troops permanently in garrison.^{[14][lower-alpha 14][lower-alpha 15]}

Fall of Maximinus Thrax

The mutiny of his army at Aquileia that brought an end to the regime of Maximinus Thrax also ended Timesitheus's term as the governor of Asia. However, he was soon employed again, this time as procurator provinciarum Lugdunensis et Aquitainicae - i.e. procurator of the two largest Gallic provinces: it would seem that he retained powerful friends in Rome despite his willingness to enter into accommodation with the military tyrant that the Senate had successfully faced down and that his administrative talents were too useful to be gainsaid. Admittedly, on this occasion he was not made an acting-governor; indeed, while procurator of Lugdunensis and Aquitainica he was, nominally at least, demoted to the rank of ducenarius. It could be that influential senators — who mistrusted equestrians who got above their social station and particularly resented brilliant high-fliers such as Timesitheus — may have intended this downgrade of his official ranking as a snub. As already intimated, however, Timesitheus is unlikely to have been either disturbed or impressed.^{[lower-alpha 16]}

Return to Rome

Timesitheus seems to have used his position in the government of the Gauls to cultivate the leaders of Gallic society.^[17] The Lyons Inscription (already mentioned) refers to him as optimus patronus (i.e. Best of Patrons) which implies that when his term of office came to an end he returned to Rome as an ambassador representing the interests the Gallic provinces. This would have facilitated his renewed access to the Imperial Court. As already indicated, Timesitheus was much admired for his culture and learning - for which much could be forgiven in Roman Society - and his rhetorical prowess no doubt did much to restore his reputation and influence with senior courtiers and senators who were dominant in Imperial politics in the early years of the reign of Gordian III.^[17]

So complete was his return to favour that, not long after his return to the City, he succeeded in marrying his daughter, Furia Sabinia Tranquillina, to Gordian, and was afterwards appointed his Praetorian Prefect, probably the consummation of his life's ambition. It has been suggested that the appointment of her father as his first minister and senior general was the Emperor's wedding-present to his young bride: there is no reason to suppose that Timesitheus had to serve terms in any of the other great Equestrian Offices of the Imperial Service (i.e. the Watch, the Corn Supply and the Government of Egypt) often regarded as necessary precursors to the Praetorian Prefecture before this appointment was bestowed upon him.^[18]

Reputation as Praetorian Prefect

Timesitheus served as Praetorian Prefect for some three years from 241 until his death in 243. The only narrative source on his term of office is the Scriptores Historiae Augustae (SHA) and, as already noted, the author of the Vita Tres Gordiani could hardly have been more fulsome in singing his praises, both as the father-in-law of the young emperor and as the protector of the Empire. This generous assessment is supported by two citations of supposed correspondence between Timesitheus and Gordian (probably invented) and a number of topoi familiarly used in Latin historiography to define a worthy servant of the state - i.e. a crackdown on sale of offices by members of the palatini,^{[lower-alpha 17]} care for the defence of the frontiers and exemplary behaviour in his capacity as commander of the Praetorian Guard. The favourable view of Timesitheus's term of office entertained by the SHA is not challenged by modern scholars - although the inadequacy of the data is acknowledged.^[19]

Achievements in office

Much of the first two years of Timesitheus's prefecture seems to have been spent producing a stable environment in which government of any sort could be carried on. His main means to this end seems to have been strengthening the authority of the Praetorian Prefecture—his own office—and to move equestrians with a fiscal background, such as himself, into positions of power.^{[lower-alpha 18]} The main effect of his manoeuvering seems to have been to ensure that the kind of men who had carried on the government under Alexander Severus were restored to effective office.^[20]

The principal challenges to his conduct of affairs seem to have been posed by senators such as Sabinianus, the governor of Africa Proconsularis, whose revolt had to be put down by the equestrian governor of Mauretania, and Tullus Menophilus, the hero of the Siege of Aquileia. The latter was executed in 241 for reasons not properly understood and to have suffered the further penalty of damnatio memoriae - i.e., formal obliteration of his name from the historical record.

Details of Timesitheus' policies and achievements as the (probable) de facto ruler of the Empire during the reign of his son-in-law are sparse. There is evidence of substantial road repairs undertaken in many parts of the Roman World which would have been of economic and strategic significance. Monuments were restored in major cities which might have lifted civilian morale as well as providing employment for sculptors, stonemasons etc. It also seems that there was a thoroughgoing adjustment of the African frontier.^[21] It is not possible to tell how far such measures reflected policy guidelines issued by Timesitheus' office to provincial authorities, still less what detailed planning was carried out there. The most that can be said with any confidence is that he does not seem to have stood in the way of functionaries, such as the procurator of Mauretania, who conceived and drove forward such works.

Persia

His main concern as the Emperor's principal minister and adviser was in dealing with the threat to the oriental provinces posed by the renascent power of Persia under one of its most effective "Kings of Kings", Shapur I.

Shapur's ambitions when he succeeded his father Ardashir in 240 were no doubt inflated by his initial successes, but there also seems no doubt that he was determined to: (i) secure strategic control of the minor states of eastern Mesopotamia that controlled access to Roman Syria across the eastern desert frontier west of the River Euphrates; and (ii) replace Rome as the hegemonic power in the Kingdom of Armenia. During the reign of Maximinus, Rome had suffered the loss of considerable territories in Mesopotamia to Ardashir which the Roman Emperor had been unable to prevent or avenge because of his internal distractions: on his accession, Shapur renewed the onslaught, capturing more of the Mesopotamian fortresses and penetrating Syria itself, where Antioch, the capital of the Roman east, may have come under threat. More seriously, perhaps, the confidence of Rome's governing elite that the Empire was capable of seeing off the Persian threat to the Oriens was seriously undermined.^[22]

In the first two years of his prefecture, Timesitheus was not able to give his attention to the threat to Rome's territories in the east posed by Shapur, but in 242 he began to organise a response appropriate to the magnitude of the crisis. Under his supervision, a powerful army was put together consisting of vexillationes from the garrisons of the Rhine and Danube provinces. This expeditionary force seems to have been very well-equipped and financed. Neither did Timesitheus neglect the issue of morale. For the last time in recorded history, war was declared with traditional Roman formalities from the temple of Janus. More significantly, before he left Rome with the Emperor, Timesitheus addressed the concerns of the Greek east by holding games in honour of Pallas Athena in her capacity as Athena Promachos - Aθηνᾶ Πρόμαχος (Athena Who-Fights-In-The-Frontline) - the patron goddess of Athens credited with saving Greece from Persia at the time of the Battle of Marathon. The object of this latter exercise was probably to reaffirm the role of Rome under the Emperor Gordian as the heir of Athens in securing the Greek world from Persian domination.^[23]

The removal of so many seasoned troops from their Rhine and Danube stations encouraged an assault across the lower Danube by the Carpi and other northern barbarians. However, Timesitheus, en route to the east through the Balkans, inflicted a serious defeat on the invaders in Thracia. He seems then to have followed the usual practice of Roman commanders after victories over barbarian peoples of obliging the defeated to provide contingents of troops. Such measures were intended not only to reinforce his army, but also to remove those restless young men who might have been disposed to make more trouble in its absence.^{[lower-alpha 19]}

On arriving in the theatre of operations he seems to have mounted a highly successful campaign against the Persians in Mesopotamia, inflicting a crushing defeat on them at the Battle of Resaena (Ras-al Ayn, Syria). This enabled the Romans to recover all their main positions in Mesopotamia, including Carrhae, Nisbis and Singara and restore their colony at Edessa in Adiabene.^{[lower-alpha 20]} The SHA suggests that it was Timesitheus' intention to follow up this success by advancing on the Persian western capital at Ctesiphon.^[24] His death meant that Shapur never had to face a powerful, well-equipped Roman army, led by a first-class general and not distracted by other enemies (as in the case of Valerian in 260) until he encountered Odenathus of Palmyra.
