twelve deniers and a Jewess six.  It has been said that there were various ancient rates levied upon Jews, in which they were treated like cattle, but this requires authentication.  During the Carnival in Rome they were forced to run in the lists, amidst the jeers of the populace.  This public outrage was stopped at a subsequent period by a tax of 300 ecus, which a deputation from the Ghetto presented on their knees to the magistrates of the city, at the same time thanking them for their protection.

When Pope Martin IV. arrived at the Council of Constance, in 1417, the Jewish community, which was as numerous as it was powerful in that old city, came in great state to present him with the book of the law (Fig. 364).  The holy father received the Jews kindly, and prayed God to open their eyes and bring them back into the bosom of his church.  We know, too, how charitable the popes were to the Jews.

In the face of the distressing position they occupied, it may be asked what powerful motive induced the Jews to live amongst nations who almost invariably treated them as enemies, and to remain at the mercy of sovereigns whose sole object was to oppress, plunder, and subject them to all kinds of vexations?  To understand this it is sufficient to remember that, in their peculiar aptness for earning and hoarding money, they found, or at least hoped to find, a means of compensation whereby they might be led to forget the servitude to which they were subjected.

They pretended, in order not to arouse the suspicion of their patients, to be practitioners from Lombardy or Spain, or even from Arabia; whether they were really clever, or only made a pretence of being so, in an art which was then very much a compound of quackery and imposture, it is difficult to say, but they acquired wealth as well as renown in its practice.  But there was another science, to the study of which they applied themselves with the utmost ardour and perseverance, and for which they possessed in a marvellous degree the necessary qualities to insure success, and that science was the science of finance.  In matters having reference to the recovering of arrears of taxes, to contracts for the sale of goods and produce of industry, to turning a royalty to account, to making hazardous commercial enterprises lucrative, or to the accumulating of large sums of money for the use of sovereigns or poor nobles, the Jews were always
