When Philippus entered his old friend’s lofty and spacious study he found him still up, sitting before a great number of rolls of manuscript, and so absorbed in his work that he did not notice his late-coming comrade till the leech bid him good-evening. His only reply was an unintelligible murmur, for some minutes longer the old man was lost in study; at last, however, he looked up at Philippus, impatiently tossing an ivory ruler-which he had been using to open and smooth the papyrus on to the table; and at the same moment a dark bundle under it began to move--this was the old man’s slave who had long been sleeping there. Three lamps on the writing-table threw a bright light on the old man and his surroundings, while the physician, who had thrown himself on a couch in a corner of the large room, remained in the dark. What startled the midnight student was his housemate’s unwonted silence; it disturbed him as the cessation of the clatter of the wheel disturbs a man who lives in a mill. He looked at his friend with surprised enquiry, but Philippus was dumb, and the old man turned once more to his rolls of manuscript. But he had lost the necessary concentration; his brown hand, in which the blue veins stood out like cords, fidgeted with the scrolls and the ivory rule, and his sunken lips, which had before been firmly closed, were now twitching restlessly. The man’s whole aspect was singular and not altogether pleasing: his lean brown figure was bent with age, his thoroughly Egyptian face, with broad cheekbones and outstanding ears, was seamed and wrinkled like oak-bark; his scalp was bare of its last hair, and his face clean-shaved, but for a few tufts of grey hair by way of beard, sprouting from the deep furrows on his cheeks and chin, like reeds from the narrow bed of a brook; the razor could not reach them there, and they gave him an untidy and uncared-for appearance. His dress answered to his face--if indeed that could be called dress which consisted of a linen apron and a white kerchief thrown over his shoulders after sundown. Still, no one meeting him in the road could have taken him for a beggar; for his linen was fine and as white as snow, and his keen, far-seeing eyes, above which, exactly in the middle, his bristly eyebrows grew strangely long and thick, shone and sparkled with clear intelligence, firm self-reliance, and a repellent severity which would no more have become an intending mendicant than the resolute and often scornful expression which played about his lips. There was nothing amiable, nothing prepossessing, nothing soft in this man’s face; and those who knew what his life had been could not wonder that the years had failed to sweeten his abrupt and contradictory acerbity or to transmute them into that kindly forbearance which old men, remembering how often they have stumbled and how many they have seen fall, sometimes find pleasure in practising.
