She early succeeded by various arts in obtaining the adhesion of Russia. An ample share of spoil was promised to the King of Poland: and that prince, governed by his favourite, Count Bruhl, readily promised the assistance of the Saxon forces. The great difficulty was with France. That the Houses of Bourbon and of Hapsburg should ever cordially co-operate in any great scheme of European policy, had long been thought, to use the strong expression of Frederic, just as impossible as that fire and water should amalgamate. The whole history of the Continent, during two centuries {207}and a half, had been the history of the mutual jealousies and enmities of France and Austria. Since the administration of Richelieu, above all, it had been considered as the plain policy of the Most Christian King to thwart on all occasions the Court of Vienna, and to protect every member of the Germanic body who stood up against the dictation of the Cæsars. Common sentiments of religion had been unable to mitigate this strong antipathy. The rulers of France, even while clothed in the Roman purple, even while persecuting the heretics of Rochelle and Auvergne, had still looked with favour on the Lutheran and Calvinistic princes who were struggling against the chief of the empire. If the French ministers paid any respect to the traditional rules handed down to them through many generations, they would have acted towards Frederic as the greatest of their predecessors acted towards Gustavus Adolphus. That there was deadly enmity between Prussia and Austria was of itself a sufficient reason for close friendship between Prussia and France. With France Frederic could never have any serious controversy. His territories were so situated that his ambition, greedy and unscrupulous as it was, could never impel him to attack her of his own accord. He was more than half a Frenchman: he wrote, spoke, read nothing but French: he delighted in French society: the admiration of the French he proposed to himself as the best reward of all his exploits. It seemed incredible that any French government, however notorious for levity or stupidity, could spurn away such an ally.
