which last he had to reckon with as does every master of policy, were always carefully circumscribed by the iron firmness o the principles to which even the most conciliatory Papacy is committed by the Church. Leo also knew, as his condemnation of Americanism in 1899 proved, how to defend energetically the rigidly centralistic Roman system, which the centrifugal, individualistic tendencies of the century made doubly necessary. The shepherd and teacher in whom "the most conservative power on earth had successfully come to terms with democracy," bequeathed to his heirs the fruits of a wise reign. When at the age of ninety-four he closed his eyes, which had pierced so far into the depths of men and things, the Catholic world realized that the prophecy Lumen de ccelo had been fulfilled.
The succeeding pontificates take us to the threshold of the present time and manifest the rich, masculine vitality of the Papal faith.
