Hadrian, who during the war had lived in a terror-stricken condition, did not content himself with merely crushing all revolt, but he desired to root out the possibility of a future uprising. For this purpose he caused a number of laws to be brought into operation, every one of which was intended to destroy Judaism, the spiritual life of the nation, in the hearts of the survivors. Hadrian named Rufus as the executor of his edicts—a man incapable of attacking an armed foe, but more competent to carry on a war of petty persecution and spying. Severus having been sent back to Britain at the end of his campaign, Rufus had the plow drawn over the town of Jerusalem and the Temple Mount, as a sign that another city should be built there. This occurred on the eventful 9th Ab, perhaps a year after the fall of Bethar.

Hadrian had the city rebuilt more towards the north, where formerly the suburbs had been. He populated the newly erected city with a colony of soldiers who had served their time, Phœnicians and Syrians. The city, Ælia Capitolina, was built in the Grecian style, with two market-places, a theater, and other public buildings, and was divided into seven quarters. Thus Hadrian succeeded in his preconceived plan of turning Jerusalem into a heathen city. On the Temple Mount a column was erected in honor of Hadrian, and a heathen temple in honor of Jupiter Capitolinus. Other statues of Roman, Greek, and Phœnician gods adorned, or rather defiled, Jerusalem. In all public edicts Jerusalem figured under its new name Ælia, and so completely was its identity forgotten, that a hundred years later a governor of Palestine asked a bishop, who said he came from Jerusalem, where that town was situated. At the south gate leading to Bethlehem a swine's head was erected in half relief, as a special annoyance to the Jews, and it was forbidden them on pain of death to pass within the outer wall of this city. Hadrian erected a shrine to Jupiter on Mount Gerizim, where the Samaritans formerly had had their temple, a place they considered as holy. On Mount Golgotha, opposite Jerusalem, a temple was erected to Venus, and in a cave at Bethlehem a statue of Adonis was worshiped. Hadrian followed the old policy of the Syrian Antiochus Epiphanes, who desecrated the Jewish holy places from prejudice and revenge, and endeavored to graft Paganism on Judaism by force of arms. He thought most effectually to break down the stubborn independence of the Jews if he could succeed in weaning them from their peculiar religious life. A decree was issued in Judæa which inflicted the severest punishments on all those who permitted themselves to be circumcised, to keep the Sabbath, or to follow the Jewish law. Only in one point did Hadrian differ from Epiphanes—he did not compel the worship of the Roman gods. All customs and habits which bore ever so slight a tinge of a religious character were, however, interdicted, such as the letter of separation for divorced wives, marriages on Wednesday, and other customs. This extension of the edict may have been a commentary of the Roman authorities in Judæa, who were better acquainted with the spirit of the Jews, and determined to enforce the imperial command in order to attain the desired end. The weary years through which Judaism passed, from the fall of Bethar till after the death of Hadrian, were called the epoch of Religious Compulsion, Danger and Persecution. The stern decrees, and a sterner enforcement of them, were a heavy blow for those who remained. The more conscientious were undecided how to behave in their critical position, whether they should keep to the hard and fast line of custom, or whether, in consideration of their thinned ranks, they should save their own lives by yielding to the exigencies of the moment.

There was probably no actual Synhedrion at that time to take up the question and give them the guidance they desired. The surviving teachers of the Law assembled in a garret in Lydda, and deliberated on this question of life and death. Amongst the members present at this assemblage were Akiba, Tarphon, and Joseph the Galilean. Doubtless Ishmael, who resembled R. Joshua in character, was also present on that occasion. There was a difference of opinion with regard to this important question. The strict elements appear to have considered that every Jew, rather than become guilty of the slightest infringement of a law, however heavy (important) or light (less important), should be ready to die the death of a martyr. Ishmael supported the opposite view. He considered that, outwardly and under compulsion, one might transgress the Law in order to preserve one's life, for the Torah enacted that its followers should live by it and not die through it. The assembly at Lydda, as usual, adopted the middle course, that a difference should be made between important precepts and those which were less weighty. The matter was put to the vote, and the decision was reached, that in order to avoid death by torture, all laws might be broken, with the exception of those prohibiting idolatry, adultery, and murder. This decision, which gives evidence of the desperate condition in which the Jews at that time found themselves, appears also to have contained a secret clause, that in case of need the Law might be evaded or neglected, but that it should be observed as far as it was possible to do so. There were many who obeyed, but who dissimulated in presence of the Roman spies and overseers. It was touching to note the petty tricks and pious frauds by which they endeavored to avoid death and yet to satisfy their conscience. The mental tortures which they suffered daily and hourly made them skilful in discovering loopholes of escape. Even Akiba on one occasion when he saw himself surrounded by Roman spies, gave a sign to his disciples to say the Shema softly and almost inaudibly, for the Roman authorities ruthlessly fulfilled the letter of their edict. A Roman inspector (quæsitor), who surprised a certain Artaban, as he was fastening Mezzuzoth to the door-posts, compelled him to pay 1000 denars for this act. Another man, Elisha, probably a survivor of the Essenes, was condemned to have his skull broken, because he was putting on Tephillin. It was dangerous even to wear the Jewish garb. Two pupils of Joshua therefore adopted the dress of the country, and when questioned on the subject they replied, "that to oppose the Imperial behest would be to commit suicide."

Ishmael describes this dreary time, when martyrdom and death dogged their every step, in the following words: "Since sinful Rome has inflicted severe laws on us, disturbed us in the performance of our religious duties, and especially prohibited the act of circumcision, we really ought not to marry, in order that we may not have children. But then the race of Abraham would die out. Therefore it is better that, for a time, the religious laws should be transgressed, rather than that a state of things should be brought about which the people would not submit to."

There were, however, many whose conscience did not permit them to make use of the freedom permitted by the Lyddan Assembly, or to employ the subterfuges which were adopted by others. They observed rigorously the religious precepts, even at the risk of suffering martyrdom. One of the younger witnesses of this sad time describes, almost in a dramatic way, the ruthlessness of the Roman authorities, who inflicted some cruel punishment for each religious ceremony. "Why shouldst thou be flogged? Because I used a lulab. Why shouldst thou be crucified? Because I ate unleavened bread at Passover. Why should ye be condemned to death by fire or by the sword? Because we read the Torah, and permitted our children to be circumcised." Yet more terrible were the deaths inflicted on the accused by the Roman tribunals, which can only be paralleled by those inflicted by the Inquisition. Red-hot balls were placed in the arm-pits, or spiked tubes passed under the nails, or damp wool was laid on the heart of one who was being burnt to death, or the skin was taken off—horrors which cause an involuntary shudder at their mere enumeration.

Notwithstanding the watchfulness of the Roman officials, it would have been possible to deceive them, had there not been Jewish renegades who betrayed to the Roman overseers the various stratagems and devices employed. These spies probably belonged to an unscrupulous class of men, who would do anything for gain, or they were Jewish Christians, who by this means thought to find favor with the Roman authorities, and to show that they were distinct from the Jews. Lastly, there were those who considered it a good work to assist in the destruction of the Jewish Law. Amongst these was Acher, who was imbued with contempt for the Law. It is said that he gave information to the Roman authorities to enable them to distinguish between religious ceremonies and those which were of no moment. For example, if the Jews were compelled to work on the Sabbath, and one had to carry a load, in order to ease his conscience, would get an assistant, and thus lessen the desecration of the Sabbath, Acher would draw attention to this ruse. Thus the Roman spies, who initiated the overseers in the various rites, were keen to notice every attempt at a religious observance.

Hadrian or his representatives directed their strictest attention to, and inflicted the severest punishments in, two especial cases—the assembling of schools and the ordination of disciples. It may have been suggested to him that the continuance of the Law depended on these two functions. If the instruction of pupils by the teachers could be stopped, and the ordination of pupils as independent teachers could be prevented, then naturally a stoppage must occur in the life-current of Judaism. It must be confessed that the Roman policy was well carried out by its supporters, and that they knew how to strike at the most vital point of Judaism. Severe sentences of death were inflicted upon those teachers who maintained schools, and on those who ordained disciples; even the communities were made answerable for them. The town and its environs, where an ordination took place, were condemned to destruction. It is possible that Acher instigated this persecution; at any rate, it is related of him that he handed over the teachers of the Law to death, and that he frightened away disciples from the study of the Law.

Amongst the friends of peace who even advised subservience to these decrees was José ben Kisma, who honored patience as the highest virtue, and hoped to effect more by submission than by bold opposition and useless self-destruction. He once met Chanina ben Teradion, who belonged to the party who were determined to give up their life for the Law. He was teaching his pupils from a scroll of the Law, which he held in his lap. José said warningly, "Seest thou, my brother, that even Heaven is favorable to the Roman empire. The Temple is destroyed; the pious are cut down, the best men are exterminated, and yet this empire exists! How canst thou dare to teach against the Imperial law? It would not surprise me if thou wert condemned to the stake together with the holy books." José was in high favor at the court of the Governor of Judæa, and when he died several persons of high rank followed his body.

Most of the Tanaites were of a different opinion, and decided rather to suffer death than to give up their meetings at the schools; they considered it of greater importance to study the Law than to observe religious precepts. A special ordinance was passed in the garret at Lydda that to teach was far more important than to merely practise the Law. As far as compulsory abstention from religious observances was concerned, the teachers of the Law had set an example of submission for the time being; but in order to preserve the knowledge of the Law itself they pressed forward to a martyr's death, as though that must be the holiest part of Judaism, to be defended even at the expense of life.

An old account speaks of ten martyrs who bled for the Law. But the names of only seven have been preserved; of the others the accounts are untrustworthy. The first to be executed was Ishmael, son of the high priest Elisha, who formulated the Thirteen Rules; with him was a certain Simon (of which name there were several). Elisha was unwilling to advise others to undergo martyrdom, but he joyfully underwent it himself. Akiba gave addresses, in which he described how Ishmael and Simon, both free from sin, had served as examples, and fallen by the hands of the executioner; and in conclusion he exhorted his scholars with these words, "Prepare for death, for terrible days are awaiting us." Akiba's turn soon came, for he held discourses in secret. On the third day of Tishri he was thrown into prison. In vain had Pappos ben Judah, one of those who advised submission at any price, warned him to give up his meetings with his pupils, because the eyes of spies were directed to the most secret places. Chance brought him and this very Pappos together in prison. Pappos lamented that he was only condemned for a worldly matter, and that he could not comfort himself with the idea that he was suffering for a great cause. Rufus, the governor and executioner, acted towards Akiba, whom he considered as the head and leader, with even greater severity than towards the others. He kept him for a long time in the prison, which was so securely guarded that no one could gain admission. The remaining teachers of the Law, who felt utterly deserted and helpless without Akiba, took all possible pains to obtain his advice in doubtful cases. Once they gave 300 denars to a messenger, who could only with great difficulty obtain access to Akiba.
