“The vistas he saw were vistas of green foliage and forest glades, all softly luminous or shot through with flashing lights. In the distance, detail was veiled and blurred by a purple haze, but behind this purple haze, he knew, was the glamour of the unknown, the lure of romance. It was like wine to him. Here was adventure, something to do with head and hand, a world to conquer-and straightaway from the back of consciousness rushed the thought: conquering, to win to her, that lily-pale spirit sitting beside him”

Jack London, Martin Eden [1909: 52].
