His room, taken by surprise, is all in darkness except the luminous ring thrown off by the candles on the piano, and the flashes flickering from the fire-place. The guests gather around informally as the piano sighs, moans, murmurs, or dreams under the fingers of the player. Heinrich Heine, the most poetic of humorists, leans on the instrument, and asks, as he listens to the music and watches the firelight, "if the roses always glowed with a flame so triumphant? if the trees at moonlight sang always so harmoniously?" Meyerbeer, one of the musical giants, sits near at hand lost in reverie; for he forgets his own great harmonies, forged with hammer of Cyclops, listening to the dreamy passion and poetry woven into such quaint fabrics of sound. Adolphe Nourrit, passionate and ascetic, with the spirit of some mediæval monastic painter, an enthusiastic servant of art in its purest, severest form, a combination of poet and anchorite, is also there; for he loves the gentle musician, who seems to be a visitor from the world of spirits. Eugène Delacroix, one of the greatest of modern painters, his keen eyes half closed in meditation, absorbs the vague mystery of colour which imagination translates from the harmony, and attains new insight and inspiration through the bright links of suggestion by which one art lends itself to another. The two great Polish poets, Niemcewicz and Mickiewicz (the latter the Dante of the Slavic race), exiles from their unhappy land, feed their sombre sorrow, and find in the wild, Oriental rhythms of the player only melancholy memories of the past. Perhaps Victor Hugo, Balzac, Lamartine, or the aged Chateaubriand, also drop in by-and-by, to recognise, in the music, echoes of the daring romanticism which they opposed to the classic and formal pedantry of the time.
