Question: When did the person who recognized Jewish synagogues as being legitimate in Rome die?

full_context: Document 1: Religion in ancient Rome: The priesthoods of public religion were held by members of the elite classes. There was no principle analogous to separation of church and state in ancient Rome. During the Roman Republic (509–27 BC), the same men who were elected public officials might also serve as augurs and pontiffs. Priests married, raised families, and led politically active lives. Julius Caesar became pontifex maximus before he was elected consul. The augurs read the will of the gods and supervised the marking of boundaries as a reflection of universal order, thus sanctioning Roman expansionism as a matter of divine destiny. The Roman triumph was at its core a religious procession in which the victorious general displayed his piety and his willingness to serve the public good by dedicating a portion of his spoils to the gods, especially Jupiter, who embodied just rule. As a result of the Punic Wars (264–146 BC), when Rome struggled to establish itself as a dominant power, many new temples were built by magistrates in fulfillment of a vow to a deity for assuring their military success.
Document 2: Roman Republic: Clodius formed armed gangs that terrorised the city and eventually began to attack Pompey's followers, who in response funded counter-gangs formed by Titus Annius Milo. The political alliance of the triumvirate was crumbling. Domitius Ahenobarbus ran for the consulship in 55 BC promising to take Caesar's command from him. Eventually, the triumvirate was renewed at Lucca. Pompey and Crassus were promised the consulship in 55 BC, and Caesar's term as governor was extended for five years. Crassus led an ill-fated expedition with legions led by his son, Caesar's lieutenant, against the Kingdom of Parthia. This resulted in his defeat and death at the Battle of Carrhae. Finally, Pompey's wife, Julia, who was Caesar's daughter, died in childbirth. This event severed the last remaining bond between Pompey and Caesar.
Document 3: Religion in ancient Rome: Roman calendars show roughly forty annual religious festivals. Some lasted several days, others a single day or less: sacred days (dies fasti) outnumbered "non-sacred" days (dies nefasti). A comparison of surviving Roman religious calendars suggests that official festivals were organized according to broad seasonal groups that allowed for different local traditions. Some of the most ancient and popular festivals incorporated ludi ("games," such as chariot races and theatrical performances), with examples including those held at Palestrina in honour of Fortuna Primigenia during Compitalia, and the Ludi Romani in honour of Liber. Other festivals may have required only the presence and rites of their priests and acolytes, or particular groups, such as women at the Bona Dea rites.
Document 4: Roman Republic: Beginning in the summer of 54 BC, a wave of political corruption and violence swept Rome. This chaos reached a climax in January of 52 BC, when Clodius was murdered in a gang war by Milo. On 1 January 49 BC, an agent of Caesar presented an ultimatum to the senate. The ultimatum was rejected, and the senate then passed a resolution which declared that if Caesar did not lay down his arms by July of that year, he would be considered an enemy of the Republic. Meanwhile, the senators adopted Pompey as their new champion against Caesar. On 7 January of 49 BC, the senate passed a senatus consultum ultimum, which vested Pompey with dictatorial powers. Pompey's army, however, was composed largely of untested conscripts. On 10 January, Caesar crossed the Rubicon with his veteran army (in violation of Roman laws) and marched towards Rome. Caesar's rapid advance forced Pompey, the consuls and the senate to abandon Rome for Greece. Caesar entered the city unopposed.
Document 5: Ashkenazi Jews: Sporadic epigraphic evidence in grave site excavations, particularly in Brigetio (Szőny), Aquincum (Óbuda), Intercisa (Dunaújváros), Triccinae (Sárvár), Savaria (Szombathely), Sopianae (Pécs), and Osijek in Croatia, attest to the presence of Jews after the 2nd and 3rd centuries where Roman garrisons were established, There was a sufficient number of Jews in Pannonia to form communities and build a synagogue. Jewish troops were among the Syrian soldiers transferred there, and replenished from the Middle East, after 175 C.E. Jews and especially Syrians came from Antioch, Tarsus and Cappadocia. Others came from Italy and the Hellenized parts of the Roman empire. The excavations suggest they first lived in isolated enclaves attached to Roman legion camps, and intermarried among other similar oriental families within the military orders of the region.Raphael Patai states that later Roman writers remarked that they differed little in either customs, manner of writing, or names from the people among whom they dwelt; and it was especially difficult to differentiate Jews from the Syrians. After Pannonia was ceded to the Huns in 433, the garrison populations were withdrawn to Italy, and only a few, enigmatic traces remain of a possible Jewish presence in the area some centuries later.
Document 6: Roman Republic: Caesar was now the primary figure of the Roman state, enforcing and entrenching his powers. His enemies feared that he had ambitions to become an autocratic ruler. Arguing that the Roman Republic was in danger, a group of senators hatched a conspiracy and assassinated Caesar at a meeting of the Senate in March 44 BC.  Mark Antony, Caesar's lieutenant, condemned Caesar's assassination, and war broke out between the two factions. Antony was denounced as a public enemy, and Caesar's adopted son and chosen heir, Gaius Octavianus, was entrusted with the command of the war against him. At the Battle of Mutina Mark Antony was defeated by the consuls Hirtius and Pansa, who were both killed.
Document 7: Roman Republic: By 59 BC an unofficial political alliance known as the First Triumvirate was formed between Gaius Julius Caesar, Marcus Licinius Crassus, and Gnaeus Pompeius Magnus ("Pompey the Great") to share power and influence. In 53 BC, Crassus launched a Roman invasion of the Parthian Empire (modern Iraq and Iran). After initial successes, he marched his army deep into the desert; but here his army was cut off deep in enemy territory, surrounded and slaughtered at the Battle of Carrhae in which Crassus himself perished. The death of Crassus removed some of the balance in the Triumvirate and, consequently, Caesar and Pompey began to move apart. While Caesar was fighting in Gaul, Pompey proceeded with a legislative agenda for Rome that revealed that he was at best ambivalent towards Caesar and perhaps now covertly allied with Caesar's political enemies. In 51 BC, some Roman senators demanded that Caesar not be permitted to stand for consul unless he turned over control of his armies to the state, which would have left Caesar defenceless before his enemies. Caesar chose civil war over laying down his command and facing trial.
Document 8: Roman Republic: After the assassination, Mark Antony formed an alliance with Caesar's adopted son and great-nephew, Gaius Octavian. Along with Marcus Lepidus, they formed an alliance known as the Second Triumvirate. They held powers that were nearly identical to the powers that Caesar had held under his constitution. As such, the Senate and assemblies remained powerless, even after Caesar had been assassinated. The conspirators were then defeated at the Battle of Philippi in 42 BC. Eventually, however, Antony and Octavian fought against each other in one last battle. Antony was defeated in the naval Battle of Actium in 31 BC, and he committed suicide with his lover, Cleopatra. In 29 BC, Octavian returned to Rome as the unchallenged master of the Empire and later accepted the title of Augustus ("Exalted One"). He was convinced that only a single strong ruler could restore order in Rome.
Document 9: Middle Ages: Roman city life and culture changed greatly in the early Middle Ages. Although Italian cities remained inhabited, they contracted significantly in size. Rome, for instance, shrank from a population of hundreds of thousands to around 30,000 by the end of the 6th century. Roman temples were converted into Christian churches and city walls remained in use. In Northern Europe, cities also shrank, while civic monuments and other public buildings were raided for building materials. The establishment of new kingdoms often meant some growth for the towns chosen as capitals. Although there had been Jewish communities in many Roman cities, the Jews suffered periods of persecution after the conversion of the empire to Christianity. Officially they were tolerated, if subject to conversion efforts, and at times were even encouraged to settle in new areas.
Document 10: Ashkenazi Jews: The origins of the Ashkenazim are obscure, and many theories have arisen speculating about their ultimate provenance. The most well supported theory is the one that details a Jewish migration through what is now Italy and other parts of southern Europe. The historical record attests to Jewish communities in southern Europe since pre-Christian times. Many Jews were denied full Roman citizenship until 212 CE, when Emperor Caracalla granted all free peoples this privilege. Jews were required to pay a poll tax until the reign of Emperor Julian in 363. In the late Roman Empire, Jews were free to form networks of cultural and religious ties and enter into various local occupations. But, after Christianity became the official religion of Rome and Constantinople in 380, Jews were increasingly marginalized.
Document 11: Assassination of Julius Caesar: Two days after the assassination, Mark Antony summoned the senate and managed to work out a compromise in which the assassins would not be punished for their acts, but all of Caesar's appointments would remain valid. By doing this, Antony most likely hoped to avoid large cracks in government forming as a result of Caesar's death. Simultaneously, Antony diminished the goals of the conspirators. The result unforeseen by the assassins was that Caesar's death precipitated the end of the Roman Republic. The Roman lower classes, with whom Caesar was popular, became enraged that a small group of aristocrats had sacrificed Caesar. Antony, who had been drifting apart from Caesar, capitalised on the grief of the Roman mob and threatened to unleash them on the Optimates, perhaps with the intent of taking control of Rome himself. But, to his surprise and chagrin, Caesar had named his grandnephew Gaius Octavius his sole heir, bequeathing him the immensely potent Caesar name as well as making him one of the wealthiest citizens in the Republic. Upon hearing of his adopted father's death, Octavius abandoned his studies in Apollonia and sailed across the Adriatic Sea to Brundisium. Octavius became Gaius Julius Caesar Octavianus or Octavian, the son of the great Caesar, and consequently also inherited the loyalty of much of the Roman populace. Octavian, aged only 18 at the time of Caesar's death, proved to have considerable political skills, and while Antony dealt with Decimus Brutus in the first round of the new civil wars, Octavian consolidated his tenuous position. Antony did not initially consider Octavius a true political threat due to his young age and inexperience, but Octavius quickly gained the support and admiration of Caesar's friends and supporters.
Document 12: Religion in ancient Rome: Several versions of a semi-official, structured pantheon were developed during the political, social and religious instability of the Late Republican era. Jupiter, the most powerful of all gods and "the fount of the auspices upon which the relationship of the city with the gods rested", consistently personified the divine authority of Rome's highest offices, internal organization and external relations. During the archaic and early Republican eras, he shared his temple, some aspects of cult and several divine characteristics with Mars and Quirinus, who were later replaced by Juno and Minerva. A conceptual tendency toward triads may be indicated by the later agricultural or plebeian triad of Ceres, Liber and Libera, and by some of the complementary threefold deity-groupings of Imperial cult. Other major and minor deities could be single, coupled, or linked retrospectively through myths of divine marriage and sexual adventure. These later Roman pantheistic hierarchies are part literary and mythographic, part philosophical creations, and often Greek in origin. The Hellenization of Latin literature and culture supplied literary and artistic models for reinterpreting Roman deities in light of the Greek Olympians, and promoted a sense that the two cultures had a shared heritage.
Document 13: Religion in ancient Rome: For at least a century before the establishment of the Augustan principate, Jews and Judaism were tolerated in Rome by diplomatic treaty with Judaea's Hellenised elite. Diaspora Jews had much in common with the overwhelmingly Hellenic or Hellenised communities that surrounded them. Early Italian synagogues have left few traces; but one was dedicated in Ostia around the mid-1st century BC and several more are attested during the Imperial period. Judaea's enrollment as a client kingdom in 63 BC increased the Jewish diaspora; in Rome, this led to closer official scrutiny of their religion. Their synagogues were recognised as legitimate collegia by Julius Caesar. By the Augustan era, the city of Rome was home to several thousand Jews. In some periods under Roman rule, Jews were legally exempt from official sacrifice, under certain conditions. Judaism was a superstitio to Cicero, but the Church Father Tertullian described it as religio licita (an officially permitted religion) in contrast to Christianity.
Document 14: Roman Republic: Caesar held both the dictatorship and the tribunate, and alternated between the consulship and the proconsulship. In 48 BC, Caesar was given permanent tribunician powers. This made his person sacrosanct, gave him the power to veto the senate, and allowed him to dominate the Plebeian Council. In 46 BC, Caesar was given censorial powers, which he used to fill the senate with his own partisans. Caesar then raised the membership of the Senate to 900. This robbed the senatorial aristocracy of its prestige, and made it increasingly subservient to him. While the assemblies continued to meet, he submitted all candidates to the assemblies for election, and all bills to the assemblies for enactment. Thus, the assemblies became powerless and were unable to oppose him.
Document 15: Religion in ancient Rome: In 380, under Theodosius I, Nicene Christianity became the official state religion of the Roman Empire. Christian heretics as well as non-Christians were subject to exclusion from public life or persecution, though Rome's original religious hierarchy and many aspects of its ritual influenced Christian forms, and many pre-Christian beliefs and practices survived in Christian festivals and local traditions.
