Thus our obscurely-born and half-schooled young medical student, the orphan son of a Finsbury stable-keeper, found himself at twenty-one, before the end of his second winter in London, fairly launched in a world of art, letters, and liberal aspirations and living in familiar intimacy with some, and friendly acquaintance with others, of the most gifted spirits of his time. The power and charm of genius already shone from him, and impressed alike his older and his younger companions. Portraits of him verbal and other exist in abundance. A small, compact, well-turned figure, broad-chested for its height, which was barely an inch over five feet; a shapely head set off by thickly clustering gold-brown hair and carried with an eager upward and forward thrust from the shoulders; the features powerful, finished, and mobile, with an expression at once bold and sensitive; the forehead sloping and not high, but broad and strong: the brows well arched above hazel-brown, liquid flashing eyes, 'like the eyes of a wild gypsy maid in colour, set in the face of a young god,' Severn calls them. To the same effect Haydon,--'an eye that had an inward look, perfectly divine, like a Delphian priestess who saw visions': and again Leigh Hunt,--'the eyes mellow and glowing, large, dark, and sensitive. At the recital of a noble action or a beautiful thought, they would suffuse with tears and his mouth tremble.' In like manner George Keats,--'John's eyes moistened and his lip quivered at the relation of any tale of generosity or benevolence or noble daring, or at sights of loveliness or distress.' And once more Haydon,--'Keats was the only man I ever met who seemed and looked conscious of a high calling, except Wordsworth.... He was in his glory in the fields. The humming of a bee, the sight of a flower, the glitter of the sun, seemed to make his nature tremble, then his eyes flashed, his cheek glowed and his mouth quivered.' 'Nothing seemed to escape him,'--I now quote paragraphs compiled by the late Mr William Sharp from many jotted reminiscences of Severn's,-- Nothing seemed to escape him, the song of a bird and the undernote of response from covert or hedge, the rustle of some animal, the changing of the green and brown lights and furtive shadows, the motions of the wind--just how it took certain tall flowers and plants--and the wayfaring of the clouds: even the features and gestures of passing tramps, the colour of one woman's hair, the smile on one child's face, the furtive animalism below the deceptive humanity in many of the vagrants, even the hats, clothes, shoes, wherever these conveyed the remotest hint as to the real self of the wearer. Withal, even when in a mood of joyous observance, with flow of happy spirits, he would suddenly become taciturn, not because he was tired, not even because his mind was suddenly wrought to some bewitching vision, but from a profound disquiet which he could not or would not explain.
