But more attractive to the girl than all this display were a number of altars which had been erected at the extreme edge of the great square, and on each of which a fire was burning. Heavy clouds of smoke went up from them in the still, pure atmosphere, like aerial columns, while the flames, paling in the beams of the morning sun, flew up through the reek as though striving to rise above it, with wan and changeful gleams of red and yellow, now curling down, and now writhing upward like snakes. Of all these fires there was not one from which the smoke did not mount straight to heaven, though each burned to a different god; and Melissa regarded it as a happy sign that none spread or failed to rise. The embers were stirred from time to time by the priests and augurs of every god of the East and West, who also superintended the sacrifices, while warriors of every province of the empire stood round in prayer. Melissa passed by all these unwonted and soul-stirring sights without a regret; her hope for the cure soon to be wrought on her lover cast all else into the shade. Still, while she looked around at the thousands who were encamped here, and gazed up at the temple where so many men were busied, like ants, it struck her that in fact all this belonged to one and was done for one alone. Those legions followed him as the dust follows the wind, the whole world trembled at his nod, and in his hand lay the life and happiness of the millions he governed. And it was at this omnipotent being, this god in human form, that her brother had mocked; and the pursuers were at his heels. This recollection troubled her joy, and when she looked in the freedman's grave and anxious face her heart began to beat heavily again. CHAPTER XII. Melissa had supposed that, according to custom, the litter would be carried up the incline or the steps, and into the Serapeum by the great door; but in consequence of the emperor's visit this could not be. The sick man was borne round the eastern side of the huge building, which covered a space on which a whole village might have stood. The door at the back, to the south, through which he was finally admitted, opened into a gallery passing by the great quadrangle where sacrifice was made, and leading to the inner rooms of the temple, to the cubicles among others. In these it was revealed to the sick in dreams by what means or remedies they might hope to be healed: and there was no lack of priests to interpret the visions, nor of physicians who came hither to watch peculiar cases, to explain to the sufferers the purport of the counsel of the gods--often very dark--or to give them the benefit of their own. One of these, a friend of Ptolemaeus, who, though he had been secretly baptized, still was one of the pastophori of the temple, was awaiting the little party, and led the way as guide.
