We must now present the reader to characters very diferent from those which have hitherto passed before his eye. Without the immortal city, along the Appia Via, there dwelt a singular and romantic visionary, of the name of Volktman. He was by birth a Dane; and nature had bestowed on him that frame of mind which might have won him a distinguished career, had she placed the period of his birth in the eleventh century. Volktman was essentially a man belonging to the past time: the character of his enthusiasm was weird and Gothic; with beings of the present day he had no sympathy; their loves, their hatreds, their politics, their literature, awoke no echo in his breast. He did not affect to herd with them; his life was solitude, and its occupation study--and study of that nature which every day unfitted him more and more for the purposes of existence. In a word, he was a reader of the stars; a believer in the occult and dreamy science of astrology. Bred up to the art of sculpture, he had early in life sought Rome, as the nurse of inspiration; but even then he had brought with him the dark and brooding temper of his northern tribe. The images of the classic world; the bright, and cold, and beautiful divinities, whose natures as well as shapes the marble simulation of life is so especially adapted to represent; spoke but little to Volktman's pre-occupied and gloomy imagination. Faithful to the superstitions and the warriors of the North, the loveliness and majesty of the southern creations but called forth in him the desire to apply the principles by which they were formed to the embodying those stern visions which his haggard and dim fancies only could invoke. This train of inspiration preserved him, at least, from the deadliest vice in a worshipper of the arts--commonplace. He was no servile and trite imitator; his very faults were solemn and commanding. But before he had gained that long experience which can alone perfect genius, his natural energies were directed to new channels. In an illness which prevented his applying to his art, he had accidentally sought entertainment in a certain work upon astrology. The wild and imposing theories of the science--if science it may be called--especially charmed and invited him. The clear bright nights of his fatherland were brought back to his remembrance; he recalled the mystic and unanalysed impressions with which he had gazed upon the lights of heaven; and he imagined that the very vagueness of his feelings was a proof of the certainty of the science.
