Louis XIII, at this period, was in so delicate a state of health as to require constant care and attention, while his sullen and self-centred disposition demanded no less watchfulness. His first preceptor was M. Vauquelin des Ivetaux, a man of great talent, and quite equal to the task of forming the mind and intellect of a Prince, but of dissolute principles and sensual habits.[188] He, however, did not long remain about the person of the boy-King, having been replaced a year after the death of Henri IV by Nicolas Le Fevre,[189] who was distinguished alike for his learning and his piety. Unfortunately for the young Louis, this excellent man only lived a year after his appointment, and was, in his turn, replaced by M. de Rivault,[190] a celebrated mathematician, who had been educated with Guy, Comte de Laval.[191] Thus, however competent these several individuals might have been to conduct his education, it will be at once evident that the perpetual changes of method and purpose to which he was subjected greatly tended to impede the progress of the illustrious pupil; and it consequently ceases to be matter of surprise that at his majority he had by no means attained to the degree of knowledge common to his age. Louis XIII knew little Latin; cared nothing for literature; but although either irritable or inert when compelled to study, could develop great energy when he was engaged in gunnery, horsemanship, or falconry. The latter pursuit was his principal amusement, His purity of heart and propriety of language were extreme, and deserve the greater mention from the contrast which they afforded to the morals and manners by which he was surrounded. He would neither permit an oath nor an obscene expression to be uttered in his presence, and never failed to rebuke any violation of his pleasure in this respect. He was passionately attached to dogs, and conversed with them, according to a contemporaneous historian, in a peculiar language;[192] but as regarded his kingly duties he was utterly incompetent. With good intentions, a love of justice, and a deep sense of religion, he was vacillating and indolent; and cared little either to assert his privileges, or to take upon himself the cares and fatigues of government while he could transfer them to others, and thus secure time to abandon himself to more congenial pursuits.
In this circumstance were comprised all the errors of his reign; as even while deeply imbued with a sense of his dignity as the sovereign of a great nation, he exhibited the feeling only in acts of petty and obstinate opposition which tended to no result, and were productive only of a want of attachment to his person, and of respect for his opinions, which increased the arrogance of the great nobles, and fostered the ambition of his ministers.
