Near by lay Pumbeditha, situated on one of the numerous canals of the Euphrates, and adorned with many palaces. Pumbeditha was none the less a thoroughly Jewish town, with a Jewish congregation, and was regarded as the capital of Jewish Babylonia. Within its territory lay several smaller towns and fortified castles, which nestled in the shadow of the capital. The inhabitants of Pumbeditha were considered acute and cunning, and were even notorious for their deceit and dishonesty. "If a man of Pumbeditha accompany thee," said a proverb, "change thy lodging."

Sixteen geographical miles (twenty-two parasangs) south of Pumbeditha was situated the town of Mata-Mechassia. It lay on the shore of a broad lake, Sora, which was in reality the Euphrates, widening out over the low-lying country; from its position on this lake the town also derived the name of Sora. It was inhabited by a mixed population of Jews and heathens. The region round Sora was one of the most fruitful parts of the whole country; by reason of its low situation it was inundated every year by the Euphrates and its tributaries and canals, and the overflow produced an Egyptian fertility. Pumbeditha was distinguished for its magnificent buildings and the cunning of its population, while Mata-Mechassia was noted for the poverty and honesty of its inhabitants. A proverb expresses this contrast in the following words: "It is better to live on the dunghills in Mechassia than in the palaces of Pumbeditha."

With these three towns of the Euphrates, Nahardea, Pumbeditha, and Mata-Mechassia, a fourth contested the supremacy: this was Machuza, situated on the Tigris, at a distance of hardly twelve miles from Ctesiphon, the capital of the Parthians. Machuza, also called Machuza-Malka, from the King's Canal (Nahar Malka) which flows in proximity to the Tigris, was situated on an eminence, and was fortified with two strong walls and a moat. Close by stood a castle, called Akra di Coche, which served as a bulwark to the capital, Ctesiphon. In spite of the importance which Machuza and its castle must have possessed for the Parthian and Persian rulers, it was, nevertheless, entirely inhabited by Jews, and an Amora expressed his surprise that the gates of its fortress were not provided with the prescribed Mezuzas.

The most noted families of Machuza were descended from proselytes, for which reason their features differed from those of the remainder of the Jewish population of Babylonia. They are described as having been very frivolous, addicted to pleasure and good cheer, and more devoted to the affairs of this world than to those of the next; they were called on this account "candidates for hell." It is related of the women of Machuza that they indulged in pleasure and idleness. Once, when a Palestinean teacher of the Law brought from Judæa to Nahardea a Halacha allowing women to wear golden head-bands set with precious stones on the Sabbath, it was remarked that only four-and-twenty women in that town availed themselves of this permission, while in one quarter alone of Machuza there were eighteen who appeared with most costly head-bands. The proximity of Ctesiphon, and its wealth, had probably some influence on the luxurious propensities and the manners of the inhabitants of Machuza. This city also, which was the residence of the king, and the newly-built town of Ardashir, which lay close by, were thickly populated with Jews. The entire district of Babylonia, with its numerous canals, resembled an island, and its wonderful fertility made of the whole country one extensive garden. There was so great a multitude of date plantations that it used to be said proverbially of the Babylonians: "A basketful of dates for a denar, and yet they do not apply themselves to the study of the Law!"

The occupations followed by the Babylonian Jews were agriculture, trades of all descriptions, and, what is of course natural in a country dependent on its canals for irrigation, the digging and cleaning of these artificial waterways; they also bred cattle, carried on commerce, undertook voyages, and cultivated certain of the fine arts.

The greatness of their numbers invested the Babylonian Jews with a certain amount of independence, and they seemed in this country almost as if in a land of their own. Their situation with regard to the rulers of the land was very favorable, as they were only called upon to pay a poll-tax (Charag) and a land-tax (Taska); there was at this period much vacant ground in the region of the Euphrates, and any one could take possession of a plot on becoming answerable for the land-tax in respect thereof. The Jews possessed their own political chief, who was called the Prince of the Captivity (Exilarch, Resh-Galutha); he was a dignitary of the Persian empire, and the fourth in rank from the king. His position with regard to the Persian kings was that of a feudatory. The Resh-Galuthas were, in fact, vassals of the Persian crown, but were simply confirmed, not chosen, by the monarch. Their badges of office were a silken cloak and a golden girdle; in later times they were surrounded by a princely luxuriousness, rode in a state carriage, possessed their own train of attendants, and an outrider to announce their approach. When they were received in solemn audience by the king, the royal attendants showed them the greatest respect, and they treated with the ruler on a footing of equality. According to the usage of Eastern princes, they were entertained with music at the moment of rising from or going to bed, a custom which was severely censured by the strict teachers of the Law, on account of the mourning for Jerusalem.

The Princes of the Captivity were descendants of the house of David, for which reason the people gladly acknowledged their sway, since it honored itself and felt honored in its princes. An old chronicle gives the full details of their names and numbers. They traced back their descent as far as Zerubbabel, the grandson of the Jewish King Jojachin, who is supposed to have returned to Babel, and to have become the ancestor of a long line of descendants. It is not until the second century that a Resh-Galutha, by name Achiya, is visible through the deep obscurity of antiquity. Another, Mar-Huna, in the time of Judah I, commanded that his body should be brought to Palestine, in order to be buried in holy ground. From that time forward, however, the succession of the Princes of the Captivity can be traced in an unbroken chain till the eleventh century. They exercised considerable influence upon the development of Jewish history in Babylonia. Their relations with the people are indicated in a few occasional passages only.

The Resh-Galutha was the supreme judge of the Jewish communities, both in civil and in criminal cases; he either administered justice in person, or delegated his office to judges of his own nomination. The ordinary coercive measure employed in cases of disobedience was the bastinado, according to Eastern custom. The princes were also entrusted with the police of the cities, the control of weights and measures, the inspection of canals, and the guardianship of public safety, to all of which various charges they appointed their own officers. It is nowhere indicated what revenues the Princes of the Captivity derived from the people; it is most probable that the primitive Asiatic custom of making presents to the sovereign obtained. It is not until later times that mention is made of regular yearly revenues drawn by them from certain regions and cities. They enjoyed an honorable public distinction which was only conferred upon such rulers as were descended from David; this consisted of having the scrolls of the Law brought to them when they had to read a portion of the Torah aloud, whereas every one else was obliged to go to the scrolls. Wealthy by reason of the income accruing from their extensive lands, they also possessed many slaves and a numerous suite of attendants; even free men placed themselves under their patronage, wearing, as sign of their fealty, the arms of their masters on their garments. The Princes of the Captivity were most sensitive with regard to these distinctive marks, refusing to pardon even the scholars whom they themselves supported, if they laid aside or even only covered over these badges. There was too much power in the hands of the Prince, and this power was too little restrained or regulated by law or tradition, for cases of arbitrariness and abuse of authority not to be forthcoming. Numerous complaints were made of the arrogance, arbitrary encroachments, or violent deeds of many of the Princes of the Captivity or their servants; they deposed the principals of the schools, appointing others in their places who were often without merit. But what power has ever restrained itself within the bounds of justice and equity? In prehistoric times, that is to say, before the knowledge of the Law had been carried to Babylonia and there domesticated, the ignorance of the Princes of the Captivity in matters of religious practice appears to have been so profound, that it was possible to transgress the laws relating to food in their house with the greatest impunity. But history tells also of meritorious persons among their numbers, who in later times combined a knowledge of the Jewish law with the possession of Jewish virtues, and whose names became a source of glory to the nation. The Princes of the Captivity often united with their political power the authority of teachers of the Law, equaling in this respect the Palestinean Patriarchs. As certain of these latter attempted to acquire political influence, in order not to be inferior to the Resh-Galutha—in which attempt, however, they were not always successful—many of the Princes of the Captivity endeavored in turn to obtain the dignity of teacher. All these various circumstances, the great number of the Jewish population of Babylonia, their independence, and the concentrated power of the Princes, stamp the history of the Jews of this region with a peculiar character; new needs arose in this country which were unknown in Judæa; new needs produced new regulations and Halachas, and thus the Law entered upon a new development in which, as already intimated, Babylon played the most important part.

During the patriarchate of Judah I, the young students of Babylon had crowded in greater numbers than in former times to the academies of Galilee, as if desirous of catching the last rays of the setting sun of religion in the mother-country, in order to enlighten therewith the land of their birth. Chiya of Cafri and his two wonderful sons, his relatives Abba-Areka and Chanina-bar-Chama, Abba and his son Samuel, were all celebrated disciples of Judah's school; they were either directly or indirectly the instructors of Babylonia. It is true that Chiya and his sons, Judah and Chiskia, did not return to their native country, but died in Galilee, where they were honored as saints; but Chiya exercised the greatest influence on the education of his disciple and nephew, Abba-Areka. Before the return to Babylonia of Abba-Areka and Samuel from the academy of Judah I in Judæa, an otherwise unknown person, Shila by name, occupied the post of principal of the school (Resh-Sidra) in Nahardea. But with the appearance of these two men, who were endowed with all the qualities requisite in order to become the founders of new schools, extensive alterations were introduced; they initiated a new departure, and raised Babylonia to the level of Judæa.

Abba (born about 175, died 247), who is known in history by the name of Rab, had completed his education, after the death of his father Aibu, at the academy of Judah I in Tiberias. Great astonishment was expressed at the early development of the wonderful talents of this youth. Through Chiya's intercession, Rab obtained a somewhat restricted advancement, which the Patriarch Gamaliel III afterwards refused to extend. Great things were expected of him in his home, and when the news of his return from Palestine was known, Samuel, who had already returned, and his friend Karna, went to meet him on the bank of the Euphrates canal. The latter overwhelmed him with questions, and even Shila, the principal of the school, bowed to his superior knowledge. After Shila's death Rab ought to have succeeded him in his office, but he refused the post in favor of his younger friend, Samuel, whose home was in Nahardea.
