In 1859, the famous German scientist, author of the works “History of the
City of Rome in the Middle Ages” and “History of the City of Athens in the
Middle Ages” Ferdinand Gregorovius wrote: “Three cities shine in the history of
mankind with a splendor of world significance; Jerusalem, Athens and Rome. All
three cities in the process of world life are contributing and mutually influencing
factors of human culture. Jerusalem, the main city of a small Jewish people, not at
all powerful, was the center of that mysterious monotheistic state from which
Christianity emerged, and thus it is the metropolis of world religion. Long after its
fall, it again receives a world-historical significance, along with Rome and in
connection with it. In ancient times, the Romans destroyed Jerusalem, the Jewish
people were scattered across the face of the earth, the meaning of the holy city
passed to Christian Rome; but in the eleventh century Jerusalem rises again, and in
the period of the crusades is the goal of the aspirations of the Christian pilgrims
and the subject of the great popular struggle between Europe and Asia. And only
then the history of Jerusalem ends with the ideas of which it was a symbol. "
