Unfortunately, we possess too few documents to write in detail the history of this dreadful episode; but everything becomes clear enough if one sees in the ruin of Julia a kind of terrible political and judicial blackmailing, tried by the friends of Tiberius to remove the chief obstacle to his return, and if one takes it that the friends of Tiberius succeeded in procuring proofs of the guilt of Julia and carried them to Augustus, not as to the head of the State, but to the father.
Dion Cassius says that "Augustus finally, although tardily, came to recognise the misdeeds of his daughter," which signifies that at a given moment, Augustus could no longer feign ignorance of her sins, because the proofs were in the power of irreconcilable enemies, who would have refused to smother the scandal. These mortal enemies of Julia could have been no other than the friends of Tiberius. Julia had violated the law on adultery made by himself; Augustus could doubt it no more.
To understand well the tragic situation in which Augustus was placed by these revelations, one must remember various things: first that the lex de adulteriis, proposed by Augustus himself, obliged the father—when the husband could not, or would not—to punish the guilty daughter, or to denounce her to the prætor, if he had not the courage to punish her himself; second, that this law arranged that if the father and the husband failed to fulfil their proper duty, any one whoever, the first comer, might in the name of public morals make the denunciation to the prætor and stand to accuse the woman and her accomplice. Tiberius, the husband, being absent at Rodi, he, Augustus, the father, must become the Nemesis of his daughter—must punish her or denounce her; if not, the friends of Tiberius could accuse her to the prætor, hale her before the quæstor, unveil to the public the shame of her private life.
What should he do? Many a father had disdainfully refused to be the executioner of his own daughter, leaving to others the grim office of applying the lex Julia. Could he imitate such an example? He was the head of the Republic, the most powerful man of the Empire, the founder of a new political order; he could decide peace and war, govern the Senate at his pleasure, exalt or abase the powerful of the earth with a nod; and exactly for this reason he dared not evade the bitter task. He feared the envy, the moral and levelling prejudices of the middle classes, which needed every now and then to slaughter in the courts some one belonging to the upper classes, in order to delude themselves that justice is equal for all. To him had been granted the greatest privileges; but precisely on this account was it dangerous to try to cover his daughter with a privileged protection as prey too delicate for public attack. And then, if he himself gave the example of disobeying his law, who would observe it? The tremendous scandal would unnerve all the moral force of his legislation, which was the base of his prestige. The moment was terrible. Imagine this old man of sixty-two wearied by forty-four years of public life, embittered by the difficulties that sprang up about him, disquieted by the dissolution of State of which he was the impotent witness, finding himself all at once facing these alternatives—either destroy his daughter, or undo all the political work over which he had laboured for thirty years; and no temporising possible!
Augustus was not a naturally cruel man, but before these alternatives his mind seems to have been for a moment convulsed by an access of grief and rage, the distant echo of which has come down to us. One moment, as Suetonius says, he had the idea of killing Julia. Then reason, pity, affection, gentler habits, prevailed. He did not give the sentence of death, but he was too practised a politician not to understand that she could not be saved; and as he had immolated Cicero, Lepidus, Antony, so he immolated her also to the necessity of preserving before Italy his prestige of severe legislator and impartial magistrate. To avoid the trial, he resolved to punish her himself with his power of pater familias according to the lex Julia, exiling her to Pandataria and announcing the divorce to her in the name of Tiberius. He then despatched to the Senate a record of what he had done, and went away to the country, where he remained a long time, says Suetonius, seeing no one, the prey to profound grief.
It seems that Julia's fall was a surprise to the public. In a day it learned that the highly popular daughter of Augustus had been condemned to exile by her father. This unexpected revelation let a storm loose in the metropolis. Even though there were not then published in Rome those vile newspapers, the pests of modern civilisation, that hunt their soldi in the mud and slime of the basest human passions, the taste for scandalous revelations, the envy of genius and fortune, the pleasure of wreaking cruelty upon the unarmed, the low delight in pouring the basest feelings upon the honour of a woman abandoned by all—these passions animated minds then, as they do to-day; nor were there then wanting, more than now, wretches that profited by them, to gather money or satisfy bad instincts, without being able to dispose of a single, miserable sheet of paper. On every side delators sprang up, and an epidemic of slanders embittered Rome; every man who had name or wealth or some relation with the family of Augustus, ran the risk of being accused as a lover of Julia. Several youths of high society, frightened by these charges, committed suicide; others were condemned. About Julia were invented and spread the most atrocious calumnies, which formed thereafter the basis for the infamous legends that have remained in history attached to her name. The traditionalist party naturally abetted this furor of accusations and inventions, made to persuade the public that a fearful corruption was hidden among the upper classes and that to cure it fire and sword must be used without pity.
The friends of Julia, the party of the young nobility, disconcerted at first by the explosion, did not delay to collect themselves and react; the populace of Rome made some great demonstrations in favour of Julia and demanded her pardon of Augustus. Many indeed, recognising that her punishment was legal, protested against the ferocity of her enemies, who had not hesitated to embitter with so terrible a scandal the old age of Augustus; protested against the mad folly of incrimination with which every part of Rome was possessed. Most people turned, the more envenomed, against Tiberius, attacking him with renewed fury as the cause of all the evil. He it was, they insisted, who had conceived the abominable scandal, willed it, imposed it upon Rome and the Empire!
If Livia and the friends of Tiberius had thought to bring him in by the gate where Julia went out, they were not slow in recognising themselves deceived. The fall of Julia struck Tiberius on the rebound in his distant island. His unpopularity, already great, grew by all the disgust that the scandal about Julia had provoked, and became so formidable that one day about this time the inhabitants of Nimes overturned his statues. It was the beginning of the Christian era, but a dark silence brooded over the Palatine; the defamed Julia was making her hard way to Pandataria; Tiberius, discredited and detested, was wasting himself in inaction at Rodi; Augustus in his empty house, disgusted, distrustful, half paralysed by deep grief, would hear to no counsels of peace, of indulgence, of reconciliation. Tiberius and Julia were equally hateful to him, and as he did not allow himself to be moved by the friends of Julia, who did not cease to implore her pardon, so he resisted the friends of Tiberius, who tried to persuade him to reconciliation. What mattered it to him if the administration of the State fell to pieces on all sides; if Germans threatened revolt; if Rome had need of the courage, of the valour, of the experience of Tiberius?
Tiberius from his retreat in Rodi kept every one in Rome afraid, beginning with Augustus. Too rich, too eager now for pleasures and comforts, Rome was almost disgusted with the virtues and the defects that had in fact created it, and which survived in Tiberius—aristocratic pride, the spirit of rigour in authority, military valour, simplicity. Peace had come, extending everywhere, with wealth, the desire for enjoyment, happiness, pleasure, freedom, loosening everywhere the firmest bonds of social discipline, persuading Rome to lay down the heavy armour it had worn for so many centuries.
In this family quarrel, which comprises a struggle of everlasting tendencies, Julia represented the new spirit that will prevail, Tiberius, the old, destined to perish; but for the time being, both spirits, however opposed, were necessary; for peace did not expand its gifts in the Empire without the protection of the great armies that fought on the Rhine and on the Danube. If the spirit of peace refreshed Rome, Italy, the Provinces, only the old aristocratic and military spirit could keep the Germans on the Rhine. As in all great social conflicts, the two opposing parties were both, in a certain measure and each from its own point of view, right. Just for that reason, the equilibrium could be found only by a continual struggle in which men on one side and on the other were destined in turn to triumph or fall according to the moment; a struggle in which Augustus, fated to act the part of judge—that is, to recognise, with a final formal sanction, a sentence already pronounced by facts—had against his will in turn to condemn some and reward others.
