It does not seem that this tax, except for its destination, was believed by the Jews to be an act of notable oppression, nor was its enforcement more inquisitorial than that of other taxes; but it became an especial weapon of blackmail in Rome and in all Italy, and this blackmail grew into dimensions so formidable that action had to be taken to suppress it.

In Rome, we may remember, there was no officer at all resembling our public prosecutor or district-attorney. The prosecution of criminals was an individual task, whether of the person aggrieved or of a citizen acting from patriotic motives. Indeed it had at one time been considered a duty of the highest insistence, and innumerable Romans had won their first distinction in this way. The delators of the early empire were in theory no different, though the reward of their activity was not the glory or popularity achieved, but the substantial one of a lump sum, or a share in the fine imposed, a practice still in vogue in our own jurisdictions. Plainly, under such circumstances, there were temptations to a form of blackmail which the Greeks knew as συκοφαντία, and the Romans as calumnia; i.e. the bringing of suits known to be unjustified, or with reckless disregard of their justification, for the purpose of sharing in some reward for doing this quasi-public service. Private prosecutors at Roman law were required to swear that they were not proceeding calumniae causa, “with blackmailing intent.”[[361]]

The opportunities presented to delators by the fiscus Iudaicus consisted in the fact that anyone of Jewish origin, with the possible exception noted above, was liable to the tax, and that there must have been many who attempted to conceal their Jewish origin in order to evade it. In view of the wide extent of the spread of the Jewish propaganda, the delation was plausible from the beginning. Suetonius tells us at first-hand recollection of a case in which the charge of evading the tax was made and successfully established.[[362]] In a very large number of cases, however, the charge was not established, but in these cases it was often apparently the policy of prudence to buy off the accuser rather than risk the uncertainties of a judicial decision. It is upon people who act in just such a way that blackmailers, συκοφαντία, calumniatores, grew fat. And the charge of evading the Jewish tax was easily made, and disproved with difficulty, since all who followed Jewish customs were amenable to it, and many Jewish customs so closely resembled the practices of certain philosophic sects that confusion on the subject was perfectly natural. We have seen this in the case of Seneca some years before this (comp. above, p. 310).

The emperor Nerva, in 96-98 C.E., removed the occasion of this abuse. Coins are extant with the legend Fisci Iudaici calumnia sublata, “To commemorate the suppression of blackmail arising from the Jewish tax.” The fiscus Iudaicus itself continued into much later times, but blackmail by means of it was ended. How this was done we are not told. But an obvious and natural method would be to abolish the money reward which the delator or prosecuting witness received for every conviction. Plainly there would be no blackmail if there was no incentive thereto.

But this reform of Nerva affected rather those who were not Jews than those who were, since in the case of actual Jews, whether by birth or conversion, the tax was enforceable and the accusation of evading it was not calumnia, but patriotic zeal. It is likely enough that the measure of Nerva discouraged prosecution, even where it was justified, but the losses which the imperial fiscus sustained by reason of the successful evasion of the tax on the part of some individuals cannot have been great, since the Jews not only publicly professed their faith, but openly and actively spread it.

In the epitome of the sixty-eighth book of Cassius Dio (i. 2), we read that this measure of Nerva was one of general amnesty for the specific crime of “impiety,” or ἀσέβεια: “Nerva ordered the acquittal of those on trial for impiety, and recalled those exiled for that crime.... He permitted no one to bring charges of impiety or of Jewish method of living.”

Unfortunately this passage is extant only in the epitome made of this book by Xiphilinus, a Byzantine monk of the eleventh century. We have no means of knowing to what extent the epitomator is stating the impression he received from his reading, largely colored by his time and personality, and to what extent he is stating the actual substance of the book. If there really was in Rome an indictable offense which consisted in adopting Jewish customs as distinguished from the general charge of impiety, such an offense does not appear elsewhere in our records. We must remember that there is no indication that the men freed by Nerva had been suffering under the despotic caprice of Domitian, but on the contrary there is the specific statement that they were being duly prosecuted under recognized forms.

It is highly likely that the two accusations which Xiphilinus gives are really one: that Nerva discouraged prosecutions for impiety, and that among the instances of men acquitted, which Dio gave, were some who were converts to Judaism, or believed to be so. In one instance, a constantly cited one, that is precisely what is the case, and that is the condemnation, in the last year of Domitian’s reign, of Flavius Clemens and Flavia Domitilla, both of them kinsmen of the emperor.[[363]]

In the case of these, we hear that Clemens was executed for “atheism,” and that under this charge many others who had lapsed into the customs of the Jews were condemned, some of them to death, others to loss of their property, Domitilla to exile.

In Suetonius we have a wholly different version (Dom. 15). Flavius Clemens, we read, was a man contemptissimae inertiae, “of thoroughly contemptible weakness of character,” but enjoying till the very last year of Domitian’s life the latter’s especial favor. Clemens’ two children were even designated for the succession. The emperor was, during this year, a prey to insane suspicions, which amounted to a real mania persecutoria, and on a sudden fit had Clemens executed. The context and general tone of the passage suggest that the charge, real or trumped up, against Clemens was one of treason, not impiety.
