Notwithstanding, we may on the other side consider that so precise and implicit an obedience as this is only due to positive and limited commands.  The employment of ambassadors is never so confined, many things in their management of affairs being wholly referred to the absolute sovereignty of their own conduct; they do not simply execute, but also, to their own discretion and wisdom, form and model their master’s pleasure.  I have, in my time, known men of command checked for having rather obeyed the express words of the king’s letters, than the necessity of the affairs they had in hand.  Men of understanding do yet, to this day, condemn the custom of the kings of Persia to give their lieutenants and agents so little rein, that, upon the least arising difficulties, they must fain have recourse to their further commands; this delay, in so vast an extent of dominion, having often very much prejudiced their affairs; and Crassus, writing to a man whose profession it was best to understand those things, and pre-acquainting him to what use this mast was designed, did he not seem to consult his advice, and in a manner invite him to interpose his better judgment?

CHAPTER XVII

OF FEAR

          “Obstupui, steteruntque comae et vox faucibus haesit.”

     ["I was amazed, my hair stood on end, and my voice stuck in my
     throat.”  Virgil, AEneid, ii. 774.]

I am not so good a naturalist (as they call it) as to discern by what secret springs fear has its motion in us; but, be this as it may, ’tis a strange passion, and such a one that the physicians say there is no other whatever that sooner dethrones our judgment from its proper seat; which is so true, that I myself have seen very many become frantic through fear; and, even in those of the best settled temper it is most certain that it begets a terrible astonishment and confusion during the fit.  I omit the vulgar sort, to whom it one while represents their great-grandsires risen out of their graves in their shrouds, another while werewolves, nightmares, and chimaeras; but even amongst soldiers, a sort of men over whom, of all others, it ought to have the least power, how often has it converted flocks of sheep into armed squadrons, reeds and bullrushes into pikes and lances, friends into enemies, and the French white cross into the red cross of Spain!  When Monsieur de Bourbon took Rome,—­[In 1527]—­an ensign who was upon guard at Borgo San Pietro was seized with such a fright upon the first alarm, that he threw himself out at a breach with his colours upon his shoulder, and ran directly upon the enemy, thinking he had retreated toward the inward defences of the city, and with much ado, seeing Monsieur de Bourbon’s people, who thought it had been a sally upon them, draw up to receive him, at last came to himself, and saw his error; and then facing about, he retreated full speed through the same breach by which he had
