One curious instance of Catherine’s sensibility to European opinion is connected with her relations to Diderot. Rulhière, afterwards well known in literature as a historian, began life as secretary to Breteuil, in the French embassy at St. Petersburg. An eyewitness of the tragedy which seated Catherine on the throne, he wrote an account of the events of the revolution of 1762. This piquant narrative, composed by a young man who had read Tacitus and Sallust was circulated in manuscript among the salons of Paris (1768). Diderot had warned Rulhière that it was infinitely dangerous to speak about princes, that not everything that is true is fit to be told, that he could not be too careful of the feelings of a great sovereign who was the admiration and delight of her people. Catherine pretended that a mere secretary of an embassy could know very little about the real springs and motives of the conspiracy. Diderot had described the manuscript as painting her in a commanding and imperious attitude. “There was nothing of that sort,” she said; “it was only a question of perishing with a madman, or saving oneself with the multitude who insisted on coming to the rescue.” What she saw was that the manuscript must be bought, and she did her best first to buy the author and then, when this failed, to have him locked up in the Bastille. She succeeded in neither. The French government were not sorry to have a scourge to their hands. All that Diderot could procure from Rulhière was a promise that the work should not be published during the Empress’s lifetime. It was actually given to the world in 1797. When Diderot was at St. Petersburg, the Empress was importunate to know the contents of the manuscript, which he had seen, but of which she was unable to procure a copy. “As far as you are concerned,” he said, “if you attach great importance, Madame, to the decencies and virtues, the worn-out rags of your sex, this work is a satire against you; but if large views and masculine and patriotic designs concern you more, the author depicts you as a great princess.” The Empress answered that this only increased her desire to read the book. Diderot himself truly enough described it as a historic romance, containing a mixed tissue of lies and truths that posterity would compare to a chapter of Tacitus.[83] Perhaps the only piece of it that posterity will really value is the page in which the writer describes Catherine’s personal appearance; her broad and open brow, her large and slightly double chin, her hair of resplendent chestnut, her eyes of a brilliant brown into which the reflections of the light brought shades of blue. “Pride,” he says, “is the true characteristic of her physiognomy. The amiability and grace which are there too only seem to penetrating eyes to be the effect of an extreme desire to please, and these seductive expressions somehow let the design of seducing be rather too clearly seen.”

The first Frenchman whom Catherine welcomed in person to her court was Falconet, of whose controversy with the philosopher we shall have a few words to say in a later chapter. This introduction to her was due to Diderot. She had entreated him to find for her a sculptor who would undertake a colossal statue of Peter the Great. Falconet was at the height of his reputation in his own country; in leaving it he seems to have been actuated by no other motive than the desire of an opportunity of erecting an immense monument of his art, though Diderot’s eloquence was not wanting. Falconet had the proverbial temperament of artistic genius. Diderot called him the Jean Jacques of sculpture. He had none of the rapacity for money which has distinguished so many artists in their dealings with foreign princes, but he was irritable, turbulent, restless, intractable. He was a chivalrous defender of poorer brethren in art, and he was never a respecter of persons. His feuds with Betzki, the Empress’s faithful factotum, were as acrid as the feuds between Voltaire and Maupertuis. Betzki had his own ideas about the statue that was to do honour to the founder of the Empire, and he insisted that the famous equestrian figure of Marcus Aurelius should be the model. Falconet was a man of genius, and he retorted that what might be good for Marcus Aurelius would not be good for Peter the Great. The courtly battle does not concern us, though some of its episodes offer tempting illustrations of biting French malice. Falconet had his own way, and after the labour of many years, a colossus of bronze bestrode a charger rearing on a monstrous mass of unhewn granite. Catherine took the liveliest interest in her artist’s work, frequently visiting his studio, and keeping up a busy correspondence. With him, as with the others, she insisted that he should stand on no ceremony, and should not spin out his lines with epithets on which she set not the smallest value. She may be said to have encouraged him to pester her with a host of his obscure countrymen in search of a living, and a little colony of Frenchmen whose names tell us nothing, hung about the Russian capital. Diderot’s account of this group of his countrymen at St. Petersburg recalls the picture of a corresponding group at Berlin. “Most of the French who are here rend and hate one another, and bring contempt both on themselves and their nation: ’tis the most unworthy set of rascals that you can imagine.”[84]

Diderot reached St. Petersburg towards the end of 1773, and he remained some five months, until the beginning of March, 1774. His impulsive nature was shocked by a chilly welcome from Falconet, but at the palace his reception was most cordial, as his arrival had been eagerly anticipated. The Empress always professed to detest ceremony and state. In a letter to Madame Geoffrin she insists, as we have already seen her doing with Falconet, on being treated to no oriental prostrations, as if she were at the court of Persia. “There is nothing in the world so ugly and detestable as greatness. When I go into a room, you would say that I am the head of Medusa: everybody turns to stone. I constantly scream like an eagle against such ways; yet the more I scream, the less are they at their ease.... If you came into my room, I should say to you,—Madame, be seated; let us chatter at our ease. You would have a chair in front of me; there would be a table between us. Et puis des bâtons rompus, tant et plus, c’est mon fort.

This is an exact description of her real behaviour to Diderot. On most days he was in her society from three in the afternoon until five or six. Etiquette was banished. Diderot’s simplicity and vehemence were as conspicuous and as unrestrained at Tsarskoe-selo as at Grandval or the Rue Taranne. If for a moment the torrent of his improvisation was checked by the thought that he was talking to a great lady, Catherine encouraged him to go on. “Allons,” she cried, “entre hommes tout est permis.” The philosopher in the heat of exposition brought his hands down upon the imperial knees with such force and iteration, that Catherine complained that he made them black and blue. She was sometimes glad to seek shelter from such zealous enforcement of truth, behind a strong table. Watchful diplomatists could not doubt that such interviews must have reference to politics. Cathcart, the English ambassador, writes to his government that M. Diderot is still with the Empress at Tsarskoe-selo, “pursuing his political intrigues.” And, amazing as it may seem, the French minister and the French ambassador both of them believed that they had found in this dreaming rhapsodical genius a useful diplomatic instrument. “The interviews between Catherine and Diderot follow one another incessantly, and go on from day to day. He told me, and I have reasons for believing that he is speaking the truth, that he has painted the danger of the alliance of Russia with the King of Prussia, and the advantage of an alliance with us. The Empress, far from blaming this freedom, encouraged him by word and gesture. ‘You are not fond of that prince,’ she said to Diderot. ‘No,’ he replied, ‘he is a great man, but a bad king, and a dealer in counterfeit coin.’ ‘Oh,’ said she laughing, ‘I have had my share of his coin.’”

The first Partition of Poland had been finally consummated in the Polish Diet in the autumn of 1773, a few weeks before Diderot’s arrival at St. Petersburg. Lewis XV., now drawing very near to his end, and D’Aiguillon, his minister, had some uneasiness at this opening of the great era of territorial revolution, and looked about in a shiftless way for an ally against Russia and Prussia. England sensibly refused to stir. Then France, as we see, was only anxious to detach Catherine from Frederick. All was shiftless and feeble, and the French government can have known little of the Empress, if they thought that Diderot was the man to affect her strong and positive mind. She told Ségur in later years what success Diderot had with her as a politician.

“I talked much and frequently with him,” said Catherine, “but with more curiosity than profit. If I had believed him, everything would have been turned upside down in my kingdom; legislation, administration, finances—all to be turned topsy-turvy to make room for impracticable theories. Yet as I listened more than I talked, any witness who happened to be present, would have taken him for a severe pedagogue, and me for his humble scholar. Probably he thought so himself, for after some time, seeing that none of these great innovations were made which he had recommended, he showed surprise and a haughty kind of dissatisfaction. Then speaking openly, I said to him: Mr. Diderot, I have listened with the greatest pleasure to all that your brilliant intelligence has inspired; and with all your great principles, which I understand very well, one would make fine books, but very bad business. You forget in all your plans of reform the difference in our positions; you only work on paper, which endures all things; it opposes no obstacle either to your imagination or to your pen. But I, poor Empress as I am, work on the human skin, which is irritable and ticklish to a very different degree. I am persuaded that from this moment he pitied me as a narrow and vulgar spirit. For the future he only talked about literature, and politics vanished from our conversation.”[85]

Catherine was mistaken, as we shall see, in supposing that Diderot ever thought her less than the greatest of men. Cathcart, the English ambassador, writes in a sour strain: “All his letters are filled with panegyrics of the Empress, whom he depicts as above humanity. His flatteries of the Grand Duke have been no less gross, but be it said to the young prince’s honour, he has shown as much contempt for such flatteries as for the mischievous principles of this pretended philosopher.”

Frederick tells D’Alembert that though the Empress overwhelms Diderot with favours, people at St. Petersburg find him tiresome and disputatious, and “talking the same rigmarole over and over again.” In her letters to Voltaire, Catherine lets nothing of this be seen. She finds Diderot’s imagination inexhaustible, and ranks him among the most extraordinary men that have ever lived; she delights in his conversation, and his visits have given her the most uncommon pleasure. All this was perhaps true enough. Catherine probably rated the philosopher at his true worth as a great talker and a singular and original genius, but this did not prevent her, any more than it need prevent us, from seeing the limits and measure. She was not one of the weaker heads who can never be content without either wholesale enthusiasm or wholesale disparagement.

Diderot had a companion who pleased her better than Diderot himself. Grimm came to St. Petersburg at this time to pay his first visit, and had a great success. “The Empress,” wrote Madame Geoffrin to King Stanislas, “lavished all her graces on Grimm. And he has everything that is needed to make him worthy of them. Diderot has neither the fineness of perception, nor the delicate tact that Grimm has, and so he has not had the success of Grimm. Diderot is always in himself, and sees nothing in other people that has not some reference to himself. He is a man of a great deal of understanding, but his nature and turn of mind make him good for nothing, and, more than that, would make him a very dangerous person in any employment. Grimm is quite the contrary.”[86]

In truth, as we have said before, Grimm was one of the shrewdest heads in the Encyclopædic party; he had much knowledge, a judgment both solid and acute, and a certain easy fashion of social commerce, free from raptures and full of good sense. Yet he was as devoted and ecstatic in his feelings about the Empress as his more impetuous friend. “Here,” he says, “was no conversation of leaps and bounds, in which idleness traverses a whole gallery of ideas that have no connection with one another, and weariness draws you away from one object to skim a dozen others. They were talks in which all was bound together, often by imperceptible threads, but all the more naturally, as not a word of what was to be said had been led up to or prepared beforehand.” Grimm cannot find words to describe her verve, her stream of brilliant sallies, her dashing traits, her eagle’s coup d’œil. No wonder that he used to quit her presence so electrified as to pass half the night in marching up and down his room, beset and pursued by all the fine and marvellous things that had been said. How much of all this is true, and how much of it is the voice of the bewildered courtier, it might be hard to decide. But the rays of the imperial sun did not so far blind his prudence, as to make him accept a pressing invitation to remain permanently in Catherine’s service. When Diderot quitted St. Petersburg, Grimm went to Italy. After an interlude there, he returned to Russia and was at once restored to high favour. When the time came for him to leave her, the Empress gave him a yearly pension of two thousand roubles, or about ten thousand livres, and with a minute considerateness that is said not to be common among the great, she presently ordered that it should be paid in such a form that he should not lose on the exchange between France and Russia. Whether she had a special object in keeping Grimm in good humour, we hardly know. What is certain is that from 1776 until the fall of the French monarchy she kept up a voluminous correspondence with him, and that he acted as an unofficial intermediary between her and the ministers at Versailles. Every day she wrote down what she wished to say to Grimm, and at the end of every three months these daily sheets were made into a bulky packet and despatched to Paris by a special courier, who returned with a similar packet from Grimm. This intercourse went on until the very height of the Revolution, when Grimm at last, in February, 1792, fled from Paris. The Empress’s helpful friendship continued to the end of her life (1796).[87]
