Looking about him with eyes grown accustomed to the semidarkness, Clearchus saw a slightly raised platform of white marble toward the rear of the temple. Three shallow steps led to a broad slab, in the middle of which was a cleft. Through this orifice curled a pale, fleeting vapor, which rose like transparent smoke for the height of a man above the platform before it vanished. It came from the stone in puffs and spirals which swayed, now this way, now that, with a peculiarly irregular and capricious impulse like the balancing of a coiled serpent.
Over the cleft was set a low tripod, the legs of which were formed of intertwined snakes wrought in gold so cunningly that every scale seemed reproduced in the bright metal. The jewelled eyes of the reptiles twinkled through the vapor which alternately hid and revealed them.
Slowly and solemnly the priestesses led the Pythia to the foot of the platform, where they gave her hands to two of the most venerable of the priests, whose office it was to conduct her to the tripod. Her lips formed themselves into a smile as she mounted the steps and the women resumed their chanting.
As she took her place upon the tripod and the priests descended, leaving her alone, a sudden thunderstorm burst above the towering crags which overhung the shrine. The wind roared down between the Phædriades with mighty strength, and a crash of thunder, leaping and reverberating from rock to cliff, shook the temple to its foundations.
"Zeus is speaking to the son of Latona!" murmured Agias, and all bowed their heads in reverence.
Filled as he was with awe, Clearchus felt reassured by the calm demeanor of the priests. He fixed his eyes on the Pythia, who remained seated on the tripod with her hands loosely folded in her lap, oblivious alike to the storm and to her surroundings. The chill vapor seemed to grow more dense. At times it hid her entirely, wrapping her in its cold embrace. The color deepened in her cheeks and the smile left her parted lips. With dilated pupils she gazed over the heads of the little group before her. Gradually her face assumed a troubled expression and her tongue began to frame broken words and fragmentary sentences the purport of which Clearchus could not understand. Suddenly she half raised her hands as though she would cover her eyes and her face contracted as with a spasm of pain.
