He breathed a deep sigh of relief. And when his servant, who had lingered to pay the toll at the bridge, came up with him, Orion dismounted and desired him to lead his horse home, for he himself wished to return on foot, alone with his thoughts. He walked meditatively and slowly under the sycamores, but he had not gone far when, on the other side of the deserted road, he heard some one overtaking him with long, quick strides. He recognized the leech Philippus at a glance and was glad, for this proved to him how senseless and unjust his doubts had been, and how little ground he had for regarding the physician as a rival; for indeed this man did not look like a happy lover. He hurried on with his head bent, as though under a heavy burthen, and clasped his hand to his forehead with a gesture of despair. No, this nocturnal wanderer had left no hour of bliss behind him; and if his demeanor was calculated to rouse any feeling it was not envy, but pity. Philippus did not heed Orion; absorbed in himself, he strode on, moaning dully, as if in pain. For a few minutes he disappeared into a house whence came loud cries of suffering, and when he came out again, he walked on, shaking his head now and then, as a man who sees many things happen which his understanding fails to account for. The end of his walk was a large, palatial building. The stucco had fallen off in places, and in the upper story the windows had been broken away till their open ings were a world too wide. In former times this house had accommodated the State officers of Finance for the province, and the ground-floor rooms had been suitably and comfortably fitted up for the Ideologos--the supreme controller of this department, who usually resided at Alexandria, but who often spent some weeks at Memphis when on a tour of inspection. But the Arabians had transferred the management of the finances of the whole country to the new capital of Fostat on the other shore of the river, and that of the monetary affairs of the decaying city had been incorporated with the treasurer’s department of the Mukaukas’ household. The senate of the city had found the expense of this huge building too heavy, and had been well content to let the lower rooms to Philippus and his Egyptian friend, Horapollo. The two men occupied different rooms, but the same slaves attended to their common housekeeping and also waited on the physician’s assistant, a modest and well-informed Alexandrian.
