But it is noticeable that while the Hebrew race possesses in the very highest degree the financial energy to handle and accumulate money, and the tenacity to keep it for a long time, it has never shown that sort of strength which can hold land or political power in adverse circumstances. In the twelfth century the Pierleoni were the masters of Rome; in the thirteenth, they had disappeared from history, though they still held the Theatre of Marcellus; in the fourteenth they seem to have perished altogether and are never heard of again. And it should not be argued that this was due to any overwhelming persecution and destruction of the Jews, since the Pierleoni's first step was an outward, if not a sincere, conversion to Christianity. In strong contrast with these facts stands the history of the Colonna. The researches of the learned Coppi make it almost certain that the Colonna descend from Theodora, the Senatress of Rome, who flourished in the year 914; Pietro della Colonna held Palestrina, and is known to have imprisoned there, 'in an empty cistern,' the governor of Campagna, in the year 1100; like the Orsini, the Colonna boast that during more than five hundred years no treaty was drawn up with the princes of Europe in which their two families were not specifically designated; and at the time of the present writing, in the last days of the nineteenth century, Colonna is still not only one of the greatest names in Europe, but the family is numerous and flourishing, unscathed by the terrible financial disasters which began to ruin Italy in 1888, not notably wealthy, but still in possession of its ancestral palace in Rome, and of immense tracts of land in the hills, in the Campagna, and in the south of Italy--actively engaged, moreover, in the representative government of Italy, strong, solid and full of life, as though but lately risen to eminence from a sturdy country stock--and all this after a career that has certainly lasted eight hundred years, and very probably nearer a thousand. Nor can any one pretend that it owes much to the power or protection of any sovereign, since the Colonna have been in almost constant opposition to the Popes in history, have been exiled and driven from Italy more than once, and have again and again suffered confiscation of all they possessed in the world. There have certainly not been in the same time so many confiscations proclaimed against the Jews.
