Of all her works the one with which we are here specially concerned presents perhaps most difficulty with regard to date. In the best copies, as in Harley MS. 4,431,[31] it is headed “Ci commence lepistre Othea la deesse, que elle envoya a Hector de Troie _quant il estoit en laage de quinze ans_,” for which reason, coupled with its dedication to Louis, Duke of Orleans, it has been too hastily assigned to 1386,[32] when Louis himself was of that age. Against this date it is almost enough to urge that Christine was then only twenty-two years old, and from all that we know of her she was not in the least likely to have begun authorship so early with a long didactic treatise mostly in prose; but, apart from this, Louis was not made Duke of Orleans until 4th June, 1391, so that the work could not have been addressed to him, as it is, under that title five years before. Another theory, that, although dedicated to Louis, it was designed for the edification of his son and heir Charles[33] is not open to the same objections; for, as the future poet-duke was born in 1391, the date would then be 1406, at which time Christine was in full career as a moralist and prose-writer, with strong views, as may be seen in her “Fais et bonnes meurs du sage roy Charles V.”, on the subject of chivalrous qualities. On the other hand, if the facts were as supposed, in addressing the work to the father she would hardly have failed to make some explanatory reference to the son. Her omission to do so therefore makes this theory hardly less untenable than the other. It is more likely that the date lies between these two extremes. The significance of the dedication may easily be overrated. It was Christine’s habit to send her works with a separate dedicatory preface to her several patrons as new-year’s gifts for no other reason probably than the hope of a tangible acknowledgment, and we know in fact that other copies of the “Épître d’Othéa” were sent both to Charles VI. and the Duke of Berry.[34] If it is necessary to look for some particular youth of fifteen to whom she wished to play the part of a moral instructress, he may perhaps be found in her own son, for whom on another occasion she wrote the “Enseignemens Moraux.”[35] Jean du Castel was probably of the required age about 1400, so that in this case the work represents, as it well may, the first-fruits of the studies in which she immersed herself shortly before, and its date moreover exactly accords with its position in her own collections of her works, where it comes after the “Dit de Poissy” (1400) and before the “Chemin de long estude” (1402).[36]
