Daunou, in his _Cours d'études historiques_,[45] has proposed a question of the same kind. "What studies," says he, "will the intending historian need to have gone through, what kinds of knowledge ought he to have acquired, in order to begin writing a work with any hope of success?" Before him, Mably, in his _Traité de l'étude de l'histoire_, had also recognised that "there are preparatory studies with which no historian can dispense." But on this subject Mably and Daunou entertained views which nowadays seem singular enough. It is instructive to mark the exact distance which separates their point of view from ours. "First of all," said Mably, "study the law of nature, public law, moral and political science." Daunou, a man of great judgment, permanent secretary to the Academy of Inscriptions and Belles-Lettres, writing about 1820, divides the studies which, in his opinion, constitute "the apprenticeship of the historian," into three classes--literary, philosophical, historical. On the "literary" studies he expatiates at great length: to begin with, the historian must "have read with attention the great models." Which great models? Daunou "does not hesitate" to place in the front rank "the masterpieces of epic poetry;" for "it is the poets who have created the art of narrative, and whoever has not learnt it from them cannot have more than an imperfect knowledge of it." He further recommends the reading of modern novels; "they will teach the method of giving an artistic pose to persons and events, of distributing details, of skilfully carrying on the thread of the narrative, of interrupting it, of resuming it, of sustaining the attention and provoking the curiosity of the reader." Finally, good historical works should be read: "Herodotus, Thucydides, Xenophon, Polybius, and Plutarch among the Greeks; Cæsar, Sallust, Livy, and Tacitus among the Latins; and among the moderns, Macchiavelli, Guicciardini, Giannone, Hume, Robertson, Gibbon, the Cardinal de Retz, Vertot, Voltaire, Raynal, and Rulhière. Not that I would exclude the others, but these will suffice to provide all the styles which are suitable for history; for a great diversity of form is to be met with in the works of these writers." In the second place come philosophical studies; a thorough mastery of "ideology, morals, and politics" is required. "As to the works from which knowledge of this kind is to be obtained, Daguesseau has instanced Aristotle, Cicero, Grotius: I should add the best ancient and modern moralists, treatises on political economy published since the middle of the last century, the writings on political science in general, and on its details and application, of Macchiavelli, Bodin, Locke, Montesquieu, Rousseau, Mably, and the most enlightened of their disciples and commentators." In the third place, before writing history, "it is evidently necessary to know it." "A writer will not give the world new information on a subject like this unless he begins by making himself
