Sunday, 13 August 1876 (1 August)

One could not imagine who, for these three days, has occupied my mind — who it is I think of, who seems to me full of interest and for whom I feel a kind of whim of sympathy, of pity, and of curiosity — not to mention a sort of interest sufficiently strange and not entirely calm. I saw his portrait three months ago at Nice: he is astride a chair, arms crossed with indolence and caprice. The features are delicate, the eyes tender and cunning, while the mouth and chin have something of the ferocity, the obstinacy, and the air of omnipotence of Peter the Great.
You know or do not know that, having come upon an engraving of the great Emperor and reread his history, three or four years ago I adored him for three days — in contempt of the Duke; or rather, no... I think it was before the Duke. The engraving represented Peter the Great at the helm of a boat in peril: all the terrified crew seems in despair — some raise their arms to heaven, others hide their faces; he alone stands upright, one foot on the gunwale, one hand at the helm and the other extended as if commanding the sea, brows knitted with that expression of will and power which, at a high degree, becomes terrible — and the square, fierce chin under tight lips and thick moustaches.
I do not much like thick moustaches — they seem inseparable from a cigar which always burns their ends and gives them an irritable and abrupt air. The person I speak of, however, has a fine, elegant moustache, untouched by scissors or pomade.
Who is this man? He? A poor lost soul, a wretch, a madman — or a thief! Grand Duke Nicholas, the Emperor's nephew and the lover of that dirty, degrading, vulgar, and criminal woman — Fanny Lear.

Notes

"Or a thief": Grand Duke Nicholas had been involved in a notorious theft of diamonds from the Imperial collection in 1874 — a scandal that led to his exile.
Grand Duke Nicholas Konstantinovich (1850–1918): son of Grand Duke Constantine Nikolayevich, thus the Emperor's nephew rather than son. His affair with Fanny Lear and the diamond theft scandal resulted in his being declared mentally ill and sent into internal exile in 1874 — a cause célèbre throughout Russia and Europe.
Fanny Lear: stage name of Hattie Blackford (c. 1848–?), an American actress and courtesan who became the Grand Duke's mistress in St Petersburg, widely condemned in Russian society. The Imperial Family blamed her for the diamond theft.
