Klea heard the high-priest accede to this request and cry in a chanting voice: "Thus he commands the night and it becomes day, and the extinguished taper and lo! it flames with brightness. If indeed thou art nigh, Oh Serapis! manifest thyself to us." At these words a bright stream of light flashed from the holy of holies, and again was suddenly extinguished when the high-priest sang: "Thus showest thou thyself as light to the children of truth, but dost punish with darkness the children of lies." "Again?" asked Krates in a voice which conveyed a desire that the answer might be 'No.' "I must trouble you," replied the high-priest. "Good! the performance went much better this time. I was always well assured of your skill; but consider the particular importance of this affair. The two kings and the queen will probably be present at the solemnity, certainly Philometor and Cleopatra will, and their eyes are wide open; then the Roman who has already assisted four times at the procession will accompany them, and if I judge him rightly he, like many of the nobles of his nation, is one of those who can trust themselves when it is necessary to be content with the old gods of their fathers; and as regards the marvels we are able to display to them, they do not take them to heart like the poor in spirit, but measure and weigh them with a cool and unbiassed mind. People of that stamp, who are not ashamed to worship, who do not philosophize but only think just so much as is necessary for acting rightly, those are the worst contemners of every supersensual manifestation." "And the students of nature in the Museum?" asked Krates. "They believe nothing to be real that they cannot see and observe." "And for that very reason," replied the high-priest, "they are often singularly easy to deceive by your skill, since, seeing an effect without a cause, they are inclined to regard the invisible cause as something supersensual. Now, open the door again and let us get out by the side door; do you, this time, undertake the task of cooperating with Serapis yourself. Consider that Philometor will not confirm the donation of the land unless he quits the temple deeply penetrated by the greatness of our god. Would it be possible, do you think, to have the new censer ready in time for the birthday of King Euergetes, which is to be solemnly kept at Memphis?" "We will see," replied Krates, "I must first put together the lock of the great door of the tomb of Apis, for so long as I have it in my workshop any one can open it who sticks a nail into the hole above the bar, and any one can shut it inside who pushes the iron bolt. Send to call me before the performance with the lights begins; I will come in spite of my wretched feet. As I have undertaken the thing I will carry it out, but for no other reason, for it is my opinion that even without such means of deception--"
