While the young men were speaking, he stroked his short grey beard and looked down at the ground in sombre gravity, as it might have seemed to the careless observer; but any one who looked closer might quickly perceive that not seldom a pleased smile, though not less often a somewhat bitter one, played upon the lips of the prudent and judicious man. He was one of those who can play with their children like a young mother, take the sorrows of another as much to heart as if they were their own, and yet who look so gloomy, and allow themselves to make such sharp speeches, that only those who are on terms of perfect confidence with them, cease to misunderstand them and fear them. There was something fretting the soul of this man, who nevertheless possessed all that could contribute to human happiness. His was a thankful nature, and yet he was conscious that he might have been destined to something greater than fate had permitted him to achieve or to be. He had remained a stone-cutter, but his sons had both completed their education in good schools in Alexandria. The elder, Antonius, who already had a house of his own and a wife and children, was an architect and artist-mechanic; the younger, Polykarp, was a gifted young sculptor. The noble church of the oasis-city had been built under the direction of the elder; Polykarp, who had only come home a month since, was preparing to establish and carry on works of great extent in his father's quarries, for he had received a commission to decorate the new court of the Sebasteion or Caesareum, as it was called--a grand pile in Alexandria--with twenty granite lions. More than thirty artists had competed with him for this work, but the prize was unanimously adjudged to his models by qualified judges. The architect whose function it was to construct the colonnades and pavement of the court was his friend, and had agreed to procure the blocks of granite, the flags and the columns which he required from Petrus' quarries, and not, as had formerly been the custom, from those of Syene by the first Cataract.
