late king’s life, and although the duke himself died on 27th April following, she completed this task within the year, sending a copy to his elder brother John, Duke of Berry, on 1st January, 1404–5. The “Livre des fais et bonnes meurs du sage roy Charles V.” is the best known and in many respects the most valuable of all her writings,[20] and it also marks the beginning of the period when she practically abandoned verse in favour of prose. Though full of interesting details, the work is not so much a regular biography as an appreciation of the king’s character from the point of view of an enthusiastic partisan. To some extent Charles V. realized Christine’s ideal of chivalry, and in her discursive way she seized her chance to enforce by his example the paramount necessity to a ruler of a sound education and virtuous principles, with covert reflections no doubt upon the political rivalries and dissolute morals which under the unhappy circumstances of his successor’s mental disease were bringing ruin upon France. Of her remaining works “La Vision,”[21] which appeared later in 1405, is of peculiar interest for its self-revelation. It was apparently meant as a reply to those who, on the ground of her sex and foreign origin, questioned her right to pose as an authority on French history and morals; but with a frank recital of her chequered fortunes and a defence of her position she mixes up a curious allegory on the mighty power of “Dame Opinion” and a discussion on the comfort to be derived from philosophy. To quote a simile which she more than once applies to herself,[22] “petite clochete grant voix sonne”; and this may certainly be said of two ambitious treatises written seemingly about 1407. One of them is the well-known “Livre des faits d’armes et de chevalerie,”[23] which is nothing less than an attempt to teach the whole art of war, grounded largely upon Vegetius and other authorities, but not without shrewd and pertinent observations of her own; while in the other, entitled “Le Corps de Policie,” she takes up the subject of civil government, more particularly with regard to the education of princes and the duties and mutual relations of the several orders in the state. The “Cité des Dames”[24] and its complement the “Livre des Trois Vertus”[25] deal on the contrary with subjects which fell less disputably within her natural sphere. As we have seen, she had already championed her sex in verse. In coming forward again in its defence, but this time in prose, she went further, taking upon herself to lay down rules of guidance for women of all ranks, which she effectively did by allegory as well as by precepts and by historical examples.
