We can understand Voltaire’s character without wading through the slough of mean scandals which sprung up like gross fungi during his stay at Berlin. Who need remember that Frederick spoke of his illustrious guest as an orange of which, when one has squeezed the juice, one throws away the skin? Or how Voltaire retorted by speaking of his illustrious host, whose royal verses he had to correct, as a man sending his dirty linen to him to wash? or, still worse, as a compound of Julius Caesar and the abbé Cotin? Nor need we examine into stories, suspicious products of Berlin malice, how Frederick stopped his guest’s supply of sugar and chocolate, and how Voltaire put his host’s candle-ends into his pocket. It is enough to know that the king and the poet gradually lost their illusions, and forgot that life was both too short and too valuable to waste in vain efforts of making believe that an illusion is other than it is. Voltaire took a childish delight in his gold key and his star, and in supping as an intimate with a king who had won five battles. His life was at once free and occupied, the two conditions of happy existence. He worked diligently at his Siècle de Louis XIV., and diverted himself with operas, comedies, and great entertainments among affable queens, charming princesses, and handsome maids of honour. Yet he could not forget the saying, which had been so faithfully carried to him, of the orange-skin. He declared that he was like the man who fell from the top of a high tower, and finding himself softly supported in the air, cried out, _Good, if it only lasts._[149] Or he was like a husband striving hard to persuade himself of the fidelity of a suspected wife. He had fits of violent nostalgia. ‘I am writing to you by the side of a stove, with drooping head and heavy heart, looking on to the River Spree, because the Spree falls into the Elbe, the Elbe into the sea, and the sea receives the Seine, and our Paris house is near the River Seine, and I say, Why am I in this palace, in this cabinet looking into this Spree, and not in our own chimney-corner?... How my happiness is poisoned, how short is life! What wretchedness to seek happiness far from you; and what remorse, if one finds it away from you.’[150] This was to Madame Denis, his niece; but a Christmas in the Berlin barrack made even a plain coquette in Paris attractive and homely. We may imagine with what tender regrets he would look back upon the old days at Cirey.
