The tribute, which is brought to Constantinople every year from all parts of Greece, consisting of silks, and purple cloths, and gold, fills many towers. These riches and buildings are equalled nowhere in the world. They say that the tribute of the city alone amounts every day to twenty thousand florins, arising from rents of hostelries and bazaars, and from the duties paid by merchants who arrive by sea and by land. The Greeks who inhabit the country are extremely rich, and possess great wealth in gold and precious stones. They dress in garments of silk, ornamented with gold and other valuable materials. They ride upon horses, and in their appearance they are like princes. The country is rich, producing all sorts of delicacies, as well as abundance of bread, meat, and wine. They are well skilled in the Greek sciences, and live comfortably, "every man under his vine and his fig tree."[152] The Greeks hire soldiers of all nations, whom they call barbarians, for the purpose of carrying on their wars with the sultan of the Thogarmim, who are called Turks. They have no martial spirit themselves, and, like women, are unfit for warlike enterprises. No Jews dwell in the city with them; they are obliged to reside beyond the one arm of the sea, where they are shut in by the channel of Sophia on one side, and they can reach the city by water only, when they want to visit it for purposes of trade. The number of Jews at Constantinople amounts to two thousand Rabbanites and five hundred Caraites[153], who live on one spot, but divided by a wall. The principal of the Rabbanites, who are learned in the law, are the rabbi R. Abtalion, R. Obadiah, R. Aaron Khuspo, R. Joseph Sargeno, and R. Eliakim the elder. Many of them are manufacturers of silk cloth, many others are merchants, some being extremely rich; but no Jew is allowed to ride upon a horse, except R. Solomon Hamitsri, who is the king's physician, and by whose influence the Jews enjoy many advantages even in their state of oppression, which is very severely felt by them; and the hatred against them is increased by the practice of the tanners, who pour out their filthy water in the streets and even before the very doors of the Jews, who, being thus defiled, become objects of contempt to the Greeks. Their yoke is severely felt by the Jews, both good and bad; for they are exposed to be beaten in the streets, and must submit to all sorts of bad treatment. Still the Jews are rich, good, benevolent, and religious men, who bear the misfortunes of their exile with humility. The quarter inhabited by the Jews is called Pera.
