Lares, as was customary before starting on a journey, Marius set forth one summer morning on his way to the famous temple which lay [30] among the hills beyond the valley of the Arnus. It was his greatest adventure hitherto; and he had much pleasure in all its details, in spite of his feverishness. Starting early, under the guidance of an old serving-man who drove the mules, with his wife who took all that was needful for their refreshment on the way and for the offering at the shrine, they went, under the genial heat, halting now and then to pluck certain flowers seen for the first time on these high places, upwards, through a long day of sunshine, while cliffs and woods sank gradually below their path. The evening came as they passed along a steep white road with many windings among the pines, and it was night when they reached the temple, the lights of which shone out upon them pausing before the gates of the sacred enclosure, while Marius became alive to a singular purity in the air. A rippling of water about the place was the only thing audible, as they waited till two priestly figures, speaking Greek to one another, admitted them into a large, white-walled and clearly lighted guest-chamber, in which, while he partook of a simple but wholesomely prepared supper, Marius still seemed to feel pleasantly the height they had attained to among the hills.

The agreeable sense of all this was spoiled by one thing only, his old fear of serpents; for it was under the form of a serpent that Aesculapius [31] had come to Rome, and the last definite thought of his weary head before he fell asleep had been a dread either that the god might appear, as he was said sometimes to do, under this hideous aspect, or perhaps one of those great sallow-hued snakes themselves, kept in the sacred place, as he had also heard was usual.

And after an hour's feverish dreaming he awoke—with a cry, it would seem, for some one had entered the room bearing a light. The footsteps of the youthful figure which approached and sat by his bedside were certainly real. Ever afterwards, when the thought arose in his mind of some unhoped-for but entire relief from distress, like blue sky in a storm at sea, would come back the memory of that gracious countenance which, amid all the kindness of its gaze, had yet a certain air of predominance over him, so that he seemed now for the first time to have found the master of his spirit. It would have been sweet to be the servant of him who now sat beside him speaking.

He caught a lesson from what was then said, still somewhat beyond his years, a lesson in the skilled cultivation of life, of experience, of opportunity, which seemed to be the aim of the young priest's recommendations. The sum of them, through various forgotten intervals of argument, as might really have happened in a [32] dream, was the precept, repeated many times under slightly varied aspects, of a diligent promotion of the capacity of the eye, inasmuch as in the eye would lie for him the determining influence of life: he was of the number of those who, in the words of a poet who came long after, must be "made perfect by the love of visible beauty." The discourse was conceived from the point of view of a theory Marius found afterwards in Plato's Phaedrus, which supposes men's spirits susceptible to certain influences, diffused, after the manner of streams or currents, by fair things or persons visibly present—green fields, for instance, or children's faces—into the air around them, acting, in the case of some peculiar natures, like potent material essences, and conforming the seer to themselves as with some cunning physical necessity. This theory,* in itself so fantastic, had however determined in a range of methodical suggestions, altogether quaint here and there from their circumstantial minuteness. And throughout, the possibility of some vision, as of a new city coming down "like a bride out of heaven," a vision still indeed, it might seem, a long way off, but to be granted perhaps one day to the eyes thus trained, was presented as the motive of this laboriously practical direction.

"If thou wouldst have all about thee like the colours of some fresh picture, in a clear [33] light," so the discourse recommenced after a pause, "be temperate in thy religious notions, in love, in wine, in all things, and of a peaceful heart with thy fellows." To keep the eye clear by a sort of exquisite personal alacrity and cleanliness, extending even to his dwelling-place; to discriminate, ever more and more fastidiously, select form and colour in things from what was less select; to meditate much on beautiful visible objects, on objects, more especially, connected with the period of youth—on children at play in the morning, the trees in early spring, on young animals, on the fashions and amusements of young men; to keep ever by him if it were but a single choice flower, a graceful animal or sea-shell, as a token and representative of the whole kingdom of such things; to avoid jealously, in his way through the world, everything repugnant to sight; and, should any circumstance tempt him to a general converse in the range of such objects, to disentangle himself from that circumstance at any cost of place, money, or opportunity; such were in brief outline the duties recognised, the rights demanded, in this new formula of life. And it was delivered with conviction; as if the speaker verily saw into the recesses of the mental and physical being of the listener, while his own expression of perfect temperance had in it a fascinating power—the merely negative element of purity, the mere freedom from taint or flaw, in exercise [34] as a positive influence. Long afterwards, when Marius read the Charmides—that other dialogue of Plato, into which he seems to have expressed the very genius of old Greek temperance—the image of this speaker came back vividly before him, to take the chief part in the conversation.

It was as a weighty sanction of such temperance, in almost visible symbolism (an outward imagery identifying itself with unseen moralities) that the memory of that night's double experience, the dream of the great sallow snake and the utterance of the young priest, always returned to him, and the contrast therein involved made him revolt with unfaltering instinct from the bare thought of an excess in sleep, or diet, or even in matters of taste, still more from any excess of a coarser kind.

When he awoke again, still in the exceeding freshness he had felt on his arrival, and now in full sunlight, it was as if his sickness had really departed with the terror of the night: a confusion had passed from the brain, a painful dryness from his hands. Simply to be alive and there was a delight; and as he bathed in the fresh water set ready for his use, the air of the room about him seemed like pure gold, the very shadows rich with colour. Summoned at length by one of the white-robed brethren, he went out to walk in the temple garden. At a distance, on either side, his guide pointed out to him the Houses of Birth and Death, erected for the reception [35] respectively of women about to become mothers, and of persons about to die; neither of those incidents being allowed to defile, as was thought, the actual precincts of the shrine. His visitor of the previous night he saw nowhere again. But among the official ministers of the place there was one, already marked as of great celebrity, whom Marius saw often in later days at Rome, the physician Galen, now about thirty years old. He was standing, the hood partly drawn over his face, beside the holy well, as Marius and his guide approached it.

This famous well or conduit, primary cause of the temple and its surrounding institutions, was supplied by the water of a spring flowing directly out of the rocky foundations of the shrine. From the rim of its basin rose a circle of trim columns to support a cupola of singular lightness and grace, itself full of reflected light from the rippling surface, through which might be traced the wavy figure-work of the marble lining below as the stream of water
