the Crusades and those who led them, there are moments in the quixotic career of St. Louis which haunt the fancy and compel our admiration: his bearing when, a captive of the Egyptian Sultan, he refused, even under threats of torture, to barter a single Christian fortress for his freedom; his lonely watch in Palestine, when for three years he patiently awaited the reinforcements that were never sent; his death-bed, when he prayed for strength to despise good fortune and not to fear adversity. Ideals may fade, but the memories of those who realise them are the world's abiding possession. If we ask what results of a more tangible sort remained from the Crusades, when the service of the Holy Sepulchre had become a legend, and the name of Crusade a byeword for whatever enterprises are most impractical and visionary, the answer must be, that they affected Europe chiefly in a negative sense and through indirect channels. They helped to discredit the conception of the Church militant; they relieved Europe of a surplus population of feudal adventurers; and they accelerated the impoverishment of those other feudal families which took an occasional part in the Holy War. It has never been proved that they led to wholesale emancipation of serfs, or wholesale enfranchisement of towns; though it is true that all such expeditions meant an increased demand for ready money. To Western civilisation they contributed very little, the truth being that there was little to be learned from the Mohammedans in Syria. It is through Palermo and Toledo, where Christianity and Islam met and mixed in peaceful intercourse, that the knowledge of Arab science and philosophy filtered into Europe. The Fourth Crusade was an exception to the general rule; it is no accident that Venetian art and architecture developed rapidly when the republic was brought into close and friendly relations with Constantinople. Through these relations, and through studying the masterpieces brought home by the Crusaders, Venetian artists recovered the antique feeling for pure form, and founded a school which was classical in spirit, Christian only in external and unessential features. The learning and literature which the Eastern Empire inherited from Rome and Athens had no attraction for Venetian merchant princes. But north of the Alps, and especially at Paris, the thirteenth century saw an increasing interest in the Greek language, and in Greek books, so far as they were useful to theologians or scholastic disputants. Politically the Fourth Crusade is memorable for its effect upon the Italian balance of power. It gave Venice an advantage over her commercial rivals, Pisa and Genoa, which she never lost; it gave her also a unique position as an intermediary between East and West; and it placed her at the head of an empire comparable to those of Athens and of Carthage, the great sea-powers of antiquity. But the nation-states of Northern Europe, who had borne the burden and heat of
