Had this been all, she would have cared no more than Eleanor or any other queen had cared, for in French drama, real or imaginary, such charges were not very serious and hardly uncomplimentary; but Iseult had never been accused, over and above her arbitrary views on the marriage-contract, of acting as an accomplice with Tristan in poisoning King Marc. French convention required that Thibaut should have poisoned Louis VIII for love of the Queen, and that this secret reciprocal love should control their lives. Fortunately for Blanche she was a devout ally of the Church, and the Church believed evil only of enemies. The legate and the prelates rallied to her support and after eight years of desperate struggle they crushed Pierre Mauclerc and saved Thibaut and Blanche. For us the poetry is history, and the facts are false. French art starts not from facts, but from certain assumptions as conventional as a legendary window, and the commonest convention is the Woman. The fact, then as now, was Power, or its equivalent in exchange, but Frenchmen, while struggling for the Power, expressed it in terms of Art. They looked on life as a drama,--and on drama as a phase of life--in which the bystanders were bound to assume and accept the regular stage-plot. That the plot might be altogether untrue to real life affected in no way its interest. To them Thibaut and Blanche were bound to act Tristan and Isolde. Whatever they were when off the stage, they were lovers on it. Their loves were as real and as reasonable as the worship of the Virgin. Courteous love was avowedly a form of drama, but not the less a force of society. Illusion for illusion, courteous love, in Thibaut's hands, or in the hands of Dante and Petrarch, was as substantial as any other convention;--the balance of trade, the rights of man, or the Athanasian Creed. In that sense the illusions alone were real; if the Middle Ages had reflected only what was practical, nothing would have survived for us.
