In 45BC, the consul Quintus Fabius Maximus died late in the year, leading to the appointment of a successor by Julius Caesar, by now at the height of his power and influence within the Roman state following his victories over the Pompeian and senatorial forces in the civil war predicated on his crossing of the Rubicon in January 49BC.
This appointment drew particular scorn and withering derision from the great orator Cicero, but why? A plebeian like Rebilus replacing a patrician in Fabius Maximus might have raised a few eyebrows given that Fabius’ colleague, Caius Trebonius, was of an equestrian family. Conservative optimates, of which Cicero was a supporter, looked less than kindly on novi homines – ‘new men’ – the first of their family to hold the consulship at the best of times, but for two to be holding that esteemed position at the same time must have really rankled.
But then Cicero himself had been a novus homo upon his election as consul in 63BC, although the virtual appointment of these ‘new men’ may have irked him somewhat as he had had to win a politically charged election to attain his position, not rely on a masquerading king doling out rewards to his lowly allies when he grew tired of being consul sine college or on the off chance that a consul died in office.
Gaius Caninius Rebilus had served in Gaul as a military tribune of Julius Caesar in 52BC, making enough of a mark that he was given command of the two legions on the exposed southern slope at the epic double siege of Alesia. With support from Titus Labienus, another of Caesar’s most trusted and talented subordinates, Rebilus and his men resisted the last concerted attack on the Roman lines on 2 October 52BC.
Continued successful service saw Rebilus entrusted with the task of chasing down the Cadurci leader, Lucterius, who had refused to surrender after Alesia. Rebilus caught up to the rebel at Uxellodunum, which Lucterius had hoped could be another focal point of Gallic resistance. Rebilus saw the opportunity to repeat the siege of Alesia for Uxellodunum was also a fortified hilltop oppidum. He initiated a blockade and then defeated a large Gallic foraging force, killing Lucterius’ lieutenant.
While on the surface, the arrival of Julius Caesar to take up overall command of the siege might reflect poorly on Rebilus, his strategy at Uxellodunum was not overturned by Caesar, who quickly agreed that taking the oppidum by force would be too costly. Uxellodunum would only fall after a prolonged disruption of its water supply (Caesar, BG VIII.40).
Upon the outbreak of civil war, Rebilus joined Caesar in Italy and was entrusted with initiating negotiations with Pompey at Brundisium, before being sent to Africa as a legatus of Gaius Scribonius Curio. He intervened decisively at the Battle of Utica, pushing Curio to take advantage of a break in the enemy lines, although it is unknown what role, if any, he played at the subsequent defeat and death of Curio at Battle of the Bagradas River. Whatever the circumstances of his escape from Africa in the aftermath, it did not sour Caesar’s view of Rebilius as he seems to have appointed him praetor for 48BC.
Rebilus is next seen serving alongside Caesar in 46BC as a propraetor during the Thapsus campaign in Africa, where he took part in the siege of Thapsus itself and accepted the surrender of the African governor, Gaius Vergilius. The following year he accompanied Caesar to Spain as a legatus, taking part in the campaign culminating in the Battle of Munda and occupying the town of Hispalis.
Clearly, Gaius Caninius Rebilus was well thought of by Julius Caesar and, while these were unusual appointments in unusual times where the rule of law and tradition was increasingly under the control of one man, having had a successful military career and served as a praetor, Rebilus was not exactly a completely left field appointment as suffect consul following the demise of Fabius Maximus. Indeed, Rebilus’ promotion to the consulship, even if just for a few hours could also show Caesar in a meritocratic light (cf. Tacitus, Hist. III.37).
However, the real reason Cicero really felt the need to get his claws out about the appointment of Rebilus to the consulship was due to how late in the year it came. Fabius Maximus had not died suddenly in October or November or even early in December. No, Fabius Maximus had dropped dead on 31 December 45BC and by just after midday, Caesar had convened a meeting of the comitia centuriata which fulfilled his wishes by duly electing Gaius Caninius Rebilus as suffect consul.
So as the consuls-elect for 44BC, Julius Caesar himself and Marcus Antonius, were due to take up their office at midnight, the consulship of Gaius Caninius Rebilus, the first of his family to achieve the feat, was to be measured not in months, weeks or even days, but in hours; a little more than eleven to be exact.
This was rendered even more laughable by the fact that Fabius Maximus and his consular colleague, Gaius Trebonius, were themselves suffect consuls, having only assumed their positions after October 45BC, when Caesar had resigned his unconstitutional (although not unprecedented) position of consul sine collega.
Cicero recorded his sarcastic summations of this appointment in a letter to his friend Manius Curius at Patrae, where in typically melodramatic style, he urged Curius to stay away from Rome and claimed that he too was thinking of leaving.
So short was Rebilus’ consulship that Cicero pointed out that “no one breakfasted” during it and heaped false praise on Rebilus for being “so astonishingly vigilant that throughout his consulship he never closed his eyes” – i.e. presuming that Rebilius was awake for the accession of his consular successors at midnight, he would have never slept whilst being consul (Cicero, Ad Fam. VII.30).
Cicero’s scathing references to the hours of Rebilus’ consulship are not just recorded in Cicero’s own works. The second book of the fifth century Saturnalia of Macrobius Ambrosius Theodosius contains a collection of witty retorts, many of which come from Cicero. As well as repeating his sarcastic jibe on the vigilance of Rebilus for having never closed his eyes while consul, Macrobius also has Cicero referring to Rebilus as “a notional consul… [who] …mounted the rostrum to assume office and at the same time to relinquish it.” He even goes as far to say that Rebilus had to ask “in whose consulship he was consul” (Macrobius, Sat. II.3.6).
Macrobius also mentions Cicero’s reaction to another case of Caesar appointing consuls for an exceedingly short period of time. Due to the prolonged nature of Caesar’s dictatorship of 48/47BC and his campaigning throughout the east, there had been no magistrates elected for 47BC. Despite the year drawing to a close, Caesar decided to rectify this by having Quintus Fufius Calenus and Publius Vatinius elected as consuls for 47BC as a reward for their service to him (cf. Caesar, BC I.87, III.26,100), seemingly as late in the year as September or even December.
In the same vein as his castigating of Rebilus, Cicero proclaimed that “Vatinius’ term of office has presented a remarkable portent, for in his consulship there has not been winter, spring, summer, or autumn.” (Macrobius, Sat. II.3.5) Vatinius later complained that Cicero, who had been a friend who had defended him in court, had not come to visit him while he was ill, to which the great orator retorted that “it was my intention to come while you were consul, but night overtook me” (Macrobius, Sat. II.3.5).
Why would Caesar open himself to such ridicule by appointing consuls for mere weeks, days and even just hours? He may have hoped that his appointing of consuls, even for such short periods of time, would be portrayed as an attempt by Caesar to retain/re-establish some kind of political normalcy – on the death of a consul, a suffect was supposed to be appointed to see out his term.
However, Caesar cannot have failed to recognise that his holding of repeated consulships and extraordinary dictatorships, his choosing of allies as consuls and the short terms of office, even if he had the interests of what was left of the res publica at heart, was going to attract ridicule.
The sensible thing probably would have been to do without a replacement and leave Trebonius to carry out any duties required for the remaining half day of 45BC or for Caesar himself to fill that short gap, perhaps by having Trebonius step down and appoint an interrex. But then Caesar himself had already been consul sine collega for much of the year before the appointment of Fabius Maximus and Trebonius in October.
Serving as consul twice in the same year was perhaps something that he was unwilling to do for unlike the rest of his irregular positions, there would appear to have been no precedent for that. It would not have helped the situation that Caesar was already slated to be consul prior for 44BC.
But then with 45BC having already seen a consul sine collega, leaving Trebonius without a colleague would also have set another unwanted precedent, as well as allowing someone else to join the very short list of consuls sine collega. On top of that, the whole rigmarole of having Trebonius step down and appoint an interrex for the remaining eleven hours of 45BC would also have attracted ridicule as constitutional overkill.
In a way then, Caesar was caught in a no-win situation constitutionally when Fabius Maximus died in the dying embers of 45BC – if he did not appoint someone, leaving Trebonius as sole consul, stepping up himself or appointing an interrex, he would be accused of forsaking the constitution once again or being overly fastidious in its application for the sake of appearances; and when he did have Rebilus appointed, Caesar was made to look a little ridiculous and cynical in using the consulship to blatantly reward a loyal supporter who may not otherwise have attained a consulship (Suetonius, Divus Iulius 76.2 claims that Caesar “gave the vacant office for a few hours to a man who asked for it”).
Perhaps because of such a political no-win situation, Caesar was happy enough to just promote one of his supporters. In the midst of the ongoing military and political crises, giving one of his military supporters a high office for eleven hours, which could be dressed up as meritocratic, rewarding loyalty and following the constitution, was worth the political barbs of the likes of Cicero.
