"Is he so old then?"
"I cannot say how long he has been a family acquaintance. Of my knowledge he is very learned in everything. He speaks all the languages I ever heard of; he passes the nights alone on the roof of his house"—
"Alone on the roof of his house!"
"Only of clear nights, you understand. A servant carries a chair and table up for him, and a roll of papers, with pen and ink, and a clock of brass and gold. The paper is a map of the heavens; and he sits there watching the stars, marking them in position on the map, the clock telling him the exact time."
"An astronomer," said Sergius.
"And an astrologer," she added; "and besides these things he is a doctor, but goes only amongst the poor, taking nothing from them. He is also a chemist; and he has tables of the plants curative and deadly, and can extract their qualities, and reduce them from fluids to solids, and proportionate them. He is also a master of figures, a science, he always terms it, the first of creative principles without which God could not be God. So, too, he is a traveller—indeed I think he has been over the known world. You cannot speak of a capital or of an island, or a tribe which he has not visited. He has servants from the farthest East. One of his attendants is an African King; and what is the strangest to me, Sergius, his domestics are all deaf and dumb."
"Impossible!"
"Nothing appears impossible to him."
"How does he communicate with them?"
"They catch his meaning from the motion of his lips. He says signs are too slow and uncertain for close explanations."
