The Princess Christian’s translation of the _Memoirs of Wilhelmine_, _Margravine of Baireuth_, is a most fascinating and delightful book. The Margravine and her brother, Frederick the Great, were, as the Princess herself points out in an admirably written introduction, ‘among the first of those questioning minds that strove after spiritual freedom’ in the last century. ‘They had studied,’ says the Princess, ‘the English philosophers, Newton, Locke, and Shaftesbury, and were roused to enthusiasm by the writings of Voltaire and Rousseau. Their whole lives bore the impress of the influence of French thought on the burning questions of the day. In the eighteenth century began that great struggle of philosophy against tyranny and worn-out abuses which culminated in the French Revolution. The noblest minds were engaged in the struggle, and, like most reformers, they pushed their conclusions to extremes, and too often lost sight of the need of a due proportion in things. The Margravine’s influence on the intellectual development of her country is untold. She formed at Baireuth a centre of culture and learning which had before been undreamt of in Germany.’ The historical value of these _Memoirs_ is, of course, well known. Carlyle speaks of them as being ‘by far the best authority’ on the early life of Frederick the Great. But considered merely as the autobiography of a clever and charming woman, they are no less interesting, and even those who care nothing for eighteenth-century politics, and look upon history itself as an unattractive form of fiction, cannot fail to be fascinated by the Margravine’s wit, vivacity and humour, by her keen powers of observation, and by her brilliant and assertive egotism. Not that her life was by any means a happy one. Her father, to quote the Princess Christian, ‘ruled his family with the same harsh despotism with which he ruled his country, taking pleasure in making his power felt by all in the most galling manner,’ and the Margravine and her brother ‘had much to suffer, not only from his ungovernable temper, but also from the real privations to which they were subjected.’ Indeed, the picture the Margravine gives of the King is quite extraordinary. ‘He despised all learning,’ she writes, ‘and wished me to occupy myself with nothing but needlework and household duties or details. Had he found me writing or reading, he would probably have whipped me.’ He ‘considered music a capital offence, and maintained that every one should devote himself to one object: men to the military service, and women to their household duties. Science and the arts he counted among the “seven deadly sins.”’ Sometimes he took to religion, ‘and then,’ says the Margravine, ‘we lived like trappists, to the great grief of my brother and myself. Every afternoon the King preached a sermon, to which we had to listen as attentively as if it proceeded from an Apostle. My brother and I were
