Caligula

by Aloys Winterling

  No accounts of the later period of Caligula’s rule mention a particular interest in learning. It is thus probably no mistake to assume that in this respect, too, he skillfully adapted his behavior on Capri to the prevailing circumstances and showed an interest in the subjects Tiberius preferred, especially since he was clearly endowed with the requisite intellectual gifts. And he did improve his relationship with the emperor, which was no doubt quite strained to begin with because of the general political atmosphere and the particular family constellation. At least their relationship appears to have grown better during Caligula’s first two years on Capri. Although Tiberius did not display any particular friendship to his great-nephew and potential successor, neither was he openly hostile.

  In the year 33, that is, in the same period when his mother and remaining brother met their deaths, Caligula was appointed quaestor, the lowest honorary political office, which carried with it automatic membership in the Senate. He was only twenty, under the usual minimum age for the quaestorship. At the same time he was given permission to be a candidate for other offices, five years before reaching the required age. This was a privilege traditionally granted to princes of the imperial family and could thus be interpreted as a positive signal for his position. And finally Tiberius had arranged for Caligula to marry Junia Claudilla (or Claudia) during a visit to Antium. She was the daughter of Marcus Junius Silanus, a former consul who had gained attention by introducing servile and flattering resolutions in the Senate. He was considered one of Tiberius’s closest associates and received the right to cast his vote first. This was an extraordinary honor that gave him the highest standing in the Roman aristocracy. In political terms such an honor was not without its dangers, as shown by the emperor’s behavior in the Senate described above. Nevertheless Silanus was clearly able to use his standing skillfully.

  Caligula’s marriage would last only a short time, and it is impossible to determine how much it meant to him. Nor can anything positive be deduced from it about Tiberius’s plans for the succession. Each of Caligula’s brothers had been married to a cousin (Nero to Julia, a granddaughter of Tiberius, and Drusus to Aemilia Lepida, a great-granddaughter of Augustus) and thereby gained the prestige conferred by an additional connection with the ruling family. No further young ladies of appropriate background were available, but the idea that one of these might take Caligula as a second husband seems not to have been considered. Julia was perhaps excluded because her testimony had contributed to Nero’s downfall. Aemilia Lepida might have been a candidate, for her participation in the fall of Drusus (III) was not discussed until years later, but both women remarried aristocrats unconnected to the imperial family. Caligula’s wife, Junia Claudilla, could boast of no comparable ancestry. Nor did the marriages of his sisters, which were certainly based on the emperor’s plans, reveal any particular favor. Only Agrippina the Younger married Gnaeus Domitius Ahenobarbus, a grandson of Marcus Antonius and Octavia, Augustus’s sister. The later emperor Nero was the offspring of this marriage. Drusilla was married to Lucius Cassius Longinus, descended from an old aristocratic family, while Livilla’s husband, Marcus Vincius, came from a less illustrious background. Tiberius’s marriage policy with regard to the children of Germanicus and Agrippina can thus be summed up as follows: None of the marriages he arranged had the slightest effect on the possibility that his own grandson, Tiberius Gemellus, might become emperor.

  Caligula’s future remained uncertain, since no doubt he stood in the way of Tiberius’s biological grandson, because of both his own descent and his popularity in Rome. During his stay on Capri he was further awarded two religious offices that were a customary part of a Roman senator’s career, but they also permit no conclusions about the emperor’s plans for him. Finally, in the year 35, Tiberius drew up a will, whose contents can be described as most definitely leaving both options open. Caligula and Gemellus received equal shares of his inheritance, in a decision that was no decision at all. Even at that point, however, the conclusion that emerged two years later upon Tiberius’s death must have been evident. The imperial office was not divisible, yet according to the will the vast imperial assets would have had to be divided, even though by this time they constituted a central part of the emperor’s authority and had taken on a character that in the modern sense of the word was public and no longer private. If it is not to be read as documentary evidence that Tiberius was incapable of making up his mind — in which case the emperor could have dispensed with it entirely — then the message it conveyed was clear: The question of the succession was to remain open.

  In addition to Caligula’s indifference to the fate of his family and his successful opportunism in dealings with the emperor and his circle, Suetonius reports that during his time on Capri the later emperor was already unable to conceal his brutal and depraved character. Caligula “was a most eager witness of the tortures and executions of those who suffered punishment, reveling at night in gluttony and adultery, disguised in a wig and a long robe, passionately devoted besides to the theatrical arts of dancing and singing, in which Tiberius very willingly indulged him, in the hope that through these his savage nature might be softened. This last was so clearly evident to the shrewd old man that he used to say now and then that to allow Gaius to live would prove the ruin of himself and of all men” (Suet. Cal. 11).

  It is easy enough to assess this account if one takes into consideration the general situation as it is reported in other, unjaundiced passages that do not touch on Caligula. From Tacitus’s account, cited above, we know that after the death of Sejanus the demeanor of those present was carefully observed when guilty sentences were announced or executions were carried out, in an attempt to discern any indication of hostility toward the emperor. Any such sign perceived in a person’s reaction was reported. Thus if Caligula was present at executions on Capri — an occurrence reported nowhere else — he was probably under close observation also. Not too much significance for interpreting his character should be attached to his failure to display much emotion. Furthermore, no evidence survives, written or archeological, to suggest the existence of taverns, brothels, or theaters on the island at that time. Or to put it more precisely: The milieu on Capri was not that of a large city like Rome, where it was easy to move about incognito. Furthermore, there are no indications that on occasional visits to the mainland Caligula would have been able — or would have wanted — to absent himself from the emperor’s entourage. Suetonius has thus ascribed to him attributes reported from the youth of a later emperor in Rome who was similarly hated, namely Nero. Finally, the suggestion that the old emperor saw through Caligula’s deception explicitly contradicts reports by Suetonius himself and others of Caligula’s ability to dissimulate, which he had perfected and which probably saved his life on Capri. It also contradicts everything that can be inferred about Tiberius’s own personality from accounts of his behavior over many years. Tiberius’s most notable trait was placing too much trust in one person (Sejanus) and responding with exaggerated distrust to everyone else; if he had one failing, it was precisely the lack of what is claimed for him in this passage: a sound knowledge of human nature. Suetonius’s account is thus utterly false. He has projected alleged qualities of the later “evil” emperor Caligula back into the time of his residence on Capri.

  For Caligula’s ultimately successful path to the imperial throne, the support of Macro, prefect of the Praetorian Guard, was decisive. All the sources are unanimous on that point. They also agree that intrigue was involved, as was only to be expected in view of the emperor’s failure to settle on a successor. Exactly how this intrigue played out cannot be determined, but that very fact suggests its secrecy was well planned — whether by Caligula himself, by Macro, or by Ennia, the prefect’s wife.

  After Junia Claudilla died in childbirth, Caligula and Ennia are supposed to have begun an affair. Philo reports the “widespread view” that because she had a sexual relationship with Caligula she was able to persuade her husband to de
fend her lover when others denounced him to Tiberius, and also to support Caligula as an aspirant to the throne. If this version is correct, then the intrigue probably originated in Ennia’s ambition to become empress. According to Suetonius, however, Caligula seduced Ennia and promised to marry her, so that she would intervene with Macro and gain his backing. Tacitus, and similarly Cassius Dio, reports a third version, that it was Macro who attempted to win Caligula’s favor by inducing Ennia to have an affair with him, hoping that a bond with the wife would also extend to the husband. This last version is certainly the most implausible. It presumes that Caligula’s succession was a foregone conclusion, regardless of whether Macro supported him or not, so that Caligula would have had no reason to seek Macro’s favor. Macro, however, is generally depicted as the most powerful man of that day after the emperor.

  It is difficult to assess the situation because we do not know how often Macro visited Capri, where Ennia must have spent considerable time. Her relationship with the future emperor probably was not sexual at all, and the married couple was simply paving the way for Caligula’s succession through a division of labor — with Macro machinating in Rome and Ennia on Capri in the role of Caligula’s confidante. Such an interpretation would fit well with the harmonious relationship among the three in the first few months after Caligula’s accession to the throne. Yet whatever the details of the intrigue were, it involved bypassing the emperor and his grandson to contrive the succession. It was an extremely risky enterprise, but again Caligula prevailed.

  He seems to have remained in danger until the very end, however. Several sources report that Tiberius was concerned for the safety of his grandson, then seventeen years old, if Caligula should become emperor. Philo writes that Macro saved Caligula’s life several times on Capri; he also mentions reports that Caligula would have been eliminated if Tiberius had lived only a little while longer, for very serious allegations had been raised against him. These charges may refer to the intrigue concerning the succession. According to Philo, toward the end of his life Tiberius was planning to name his biological grandson as his successor. Dio tells a different story: Tiberius considered Gemellus illegitimate, the child of Livilla’s liaison with Sejanus, and therefore he preferred Caligula. Josephus provides yet another version, that Tiberius decided to regard a chance occurrence as an omen and indicator of God’s will. The conflicting accounts suggest that the succession was an open question until the last moment. Tacitus probably came closest to the truth when he concluded that Tiberius could not summon the strength to make a decision.

  Tiberius died on 16 March in the year 37. In the preceding weeks the old man had approached the city of his birth for the last time, but he died at Misenum, the base of the Roman fleet. Various rumors about his death found their way into circulation. According to one, after death seemed to have occurred and preparations were already under way to proclaim Caligula emperor, Tiberius is supposed to have regained consciousness suddenly and asked for food. While everyone else present stood rooted to the spot in terror, Macro ran into the bed chamber, threw covers over the emperor, and smothered him. Another version declared that Caligula had hastened his adoptive grandfather’s demise, first with poison and then by strangling him with his own hands. According to a third account, Caligula had first starved the emperor and then suffocated him with Macro’s help. Regardless of how the emperor actually died, even in their diversity the reports of the death of the emperor — who over the years had become ever more odious — confirm the contemporaries’ image of the center of power, where Caligula had lived for six years: All who took part were in mortal peril.

  The same day, members of the Praetorian Guard in Misenum proclaimed Caligula imperator. Following arrangements with the consuls and leading senators, the Roman Senate accepted the new disposition of power. On 18 March Tiberius’s last will and testament was set aside on the grounds that he had been of unsound mind when he made it. The Senate — an ancient and honorable institution that in the preceding two decades had both lost a large number of members to violence and suffered a decline in morale — recognized the son of Germanicus as emperor in absentia. After his arrival in Rome on 28 March, “the right and the power to decide on all affairs” was conferred on him (Suet. Cal. 14.1). With this step Caligula, at the age of twenty-four, became Gaius Caesar Augustus Germanicus and ruler of the Roman Empire.

  TWO

  Two Years as Princeps

  A YOUNG AUGUSTUS

  The journey from Misenum to Rome took ten days. As the young emperor, dressed in mourning, accompanied the body of Tiberius, he received striking demonstrations of sympathy from the population. “His progress was marked by altars, victims, and blazing torches, and he was met by a dense and joyful throng, who called him, besides other propitious names, their ‘star,’ their ‘chick,’ their ‘babe,’ and their ‘nursling’ ” (Suet. Cal. 13). Germanicus’s prestige and popularity had survived the reign of Tiberius and were now transferred to his remaining son — in more intense form because the other family members had met such tragic fates. Suetonius reports that Caligula was “the emperor most earnestly desired” (exoptatissimus princeps) by the inhabitants of the provinces and by the soldiers who had known him as a child, just as he was also by the whole population of the city of Rome (Suet. Cal. 13). When he entered the capital, the center of the ancient world in which he had not set foot for the past six years, the celebrations are said to have gone on for almost three months, and more than 160,000 animals were sacrificed — and eaten.

  But how did the aristocracy react to the twenty-four-year-old new ruler? Would the flattery, denunciations, and intrigue continue as they had under Tiberius? And how would the young Augustus behave toward the senators? It was from their circle, after all, that the criminal charges against his mother and brothers had originated, and the Senate as a whole had pronounced the verdicts against them. After nearly seventy years of sole rule under Augustus and Tiberius, it had become evident that an emperor’s success or failure rested above all on the delicate business of communicating with his fellow aristocrats.

  Caligula’s first step was to deliver a speech at a session of the Senate to which representatives of the equestrian order and the people had been invited. According to Cassius Dio’s account, he flattered the senators, promising to share his power with them and to do all he could to please them. He even referred to himself as their son and ward. Specifically, he announced that he was putting an end to trials for maiestas, which had had such dreadful effects on the aristocracy and its relationship with the emperor. All those who had been exiled or imprisoned under Tiberius would regain their freedom, Caligula declared. He ordered all the documents connected with those trials, which his predecessor had preserved and which also concerned the charges against his mother and his brothers, to be publicly burned in the Forum (not without securing copies of them first, as it would later transpire). This was an effort to assuage the fears of senators and knights who had played a prominent role in the trials, and to close this terrible chapter of the past. Caligula emphasized his intention truly to begin anew by his reaction to the first denunciation for conspiracy he received: He ignored it, and declared that he could have done nothing to arouse anyone’s hatred. He would pay no heed to informers.

  How to commemorate the deceased emperor was another question. As Tiberius’s adopted grandson and successor Caligula had to preserve the proper degree of respect for his memory, but the dominant attitude in the Senate was still detestation. In his first written communication to the Senate Caligula had requested that Tiberius be granted the same honors that Augustus had received after death, elevation to the status of a god and inclusion in the Roman pantheon. The senators had not overcome their reluctance to comply with this request before the new emperor’s arrival, but neither had they taken the opposite step (which would no doubt have reflected their feelings more accurately) of officially c
ondemning his memory (damnatio memoriae) and thereby expunging him from the public records. Caligula let the matter rest, in an undecided state that certainly matched the personality of the deceased; the body lay in state and was then buried in Augustus’s mausoleum in an elaborate public ceremony. Delivering the funeral oration, the new emperor mainly recalled Augustus and Germanicus and placed himself in their tradition.

  Caligula then proceeded to honor Tiberius’s bequests — even though his will had been declared invalid. The members of the Praetorian Guard received 1,000 sesterces each, roughly the annual pay of an ordinary soldier. Forty-five million sesterces were paid out to the people of Rome; the urban cohorts, a kind of police force, and the firemen, who also exercised paramilitary functions, each received 500; and every citizen soldier in the Empire was given 300 sesterces. In addition the new emperor ordered distribution of the bequests in Livia’s will, which Tiberius had ignored after her death eight years earlier. Finally Caligula added his own contribution: He doubled the amount for the Praetorian Guard, and granted 300 sesterces to the head of every family in Rome. The money that rained down on the citizens of Rome at Caligula’s accession left a lasting impression of his generosity, a virtue loved above all by soldiers and the urban plebs, and one that made emperors popular.

  The payments to the Praetorian Guard allowed Caligula to provide a striking reminder of his own power. Before the assembled Senate, he inspected his bodyguards, who had sworn an oath of loyalty to him. It was not lost on the spectators at the drill that the officers and men under Macro’s command were largely the same men who had not so long ago, on the orders of the previous emperor or Sejanus, arrested, tortured, or beheaded no small number of their Senate colleagues.

  A further symbolic act honored the members of Caligula’s immediate family who had predeceased him. Despite stormy seas Caligula sailed at once to the islands where his mother and brother had died, exhumed their remains himself, and brought them back to Ostia, Rome’s port. From there he had them transported up the Tiber to the city by ship. At midday, when the streets were most crowded, prominent knights carried the two urns through Rome on litters normally used for transporting statues of gods. The procession ended at the Mausoleum of Augustus, where the remains were interred. The whole ceremony was arranged to resemble a delayed triumph for the family of Germanicus: A field marshal’s standard flew from the stern of the ship, and Caligula wore a purple-bordered toga and was accompanied by lictors, as if he himself were a victorious commander. It was decreed that an image of his mother, Agrippina, mounted on a carriage, would henceforth accompany all festival processions. The month of September was renamed after Germanicus, who joined Julius Caesar and Augustus as the only men so honored.
