Frederic had a keen eye for the foibles of others, and loved to communicate his discoveries. He had some talent for sarcasm, and considerable skill in detecting; the sore places where sarcasm would be most acutely felt. His vanity, as well as his malignity, found gratification in the vexation and confusion of those who smarted under his caustic jests. Yet in truth his success on these occasions belonged quite as much to the king as to the wit. We read that Commodus descended, sword in hand, into the arena against a wretched gladiator, armed only with a foil of lead, and, after shedding the blood of the helpless victim, struck medals to commemorate the inglorious victory. The triumphs of Frederic in the war of repartee were of much the same kind. How to deal with him was the most puzzling of questions. To appear constrained in his presence was to disobey his commands, and to spoil his amusement. Yet if his associates were enticed by his graciousness to indulge in the familiarity of a cordial intimacy, he was certain to make them repent of their presumption by some cruel humiliation. To resent his affronts was perilous; yet not to resent them was to deserve and to invite them. In his view, those who mutinied were insolent and ungrateful; those who submitted were curs made to receive bones and kickings with the same fawning patience. It is, indeed, difficult to conceive how any thing short of the rage of hunger should have induced men to bear the misery of being the associates of the Great King. It was no lucrative post. His Majesty was as severe and economical in his friendships as in the other charges of his establishment, {193}and as unlikely to give a rixdollar too much for his guests as for his dinners. The sum which he allowed to a poet or a philosopher was the very smallest sum for which such poet or philosopher could be induced to sell himself into slavery; and the bondsman might think himself fortunate, if what had been so grudgingly given was not, after years of suffering, rudely and arbitrarily withdrawn.
