Marius the Epicurean by Walter Pater — Read

Mirum est ut animus agitatione motuque corporis excitetur. / Pliny's Letters

Many points in that train of thought, its harder and more energetic practical details especially, at first surmised but vaguely in the intervals of his visits to the tomb of Flavian, attained the coherence of formal principle amid the stirring incidents of the journey, which took him, still in all the buoyancy of his nineteen years and greatly expectant, to Rome. That summons had come from one of the former friends of his father in the capital, who had kept himself acquainted with the lad's progress, and, assured of his parts, his courtly ways, above all of his beautiful penmanship, now offered him a place, virtually that of an amanuensis, near the person of the philosophic emperor. The old town-house of his family on the Caelian hill, so long neglected, might well require his personal care; and Marius, relieved a little by his preparations for travelling from a certain over-tension of spirit in which he had lived of late, was presently on his way, to await introduction to Aurelius, on his expected return home, after a first success, illusive enough as it was soon to appear, against the invaders from beyond the Danube.
