'And what,' whispered Arbaces to one of the bystanders, who was a merchant engaged in the Alexandrian trade, which trade had probably first introduced in Pompeii the worship of the Egyptian goddess--'what occasion now assembles you before the altars of the venerable Isis? It seems, by the white robes of the group before me, that a sacrifice is to be rendered; and by the assembly of the priests, that ye are prepared for some oracle. To what question is it to vouchsafe a reply?' 'We are merchants,' replied the bystander (who was no other than Diomed) in the same voice, 'who seek to know the fate of our vessels, which sail for Alexandria to-morrow. We are about to offer up a sacrifice and implore an answer from the goddess. I am not one of those who have petitioned the priest to sacrifice, as you may see by my dress, but I have some interest in the success of the fleet--by Jupiter! yes. I have a pretty trade, else how could I live in these hard times? The Egyptian replied gravely--'That though Isis was properly the goddess of agriculture, she was no less the patron of commerce.' Then turning his head towards the east, Arbaces seemed absorbed in silent prayer. And now in the centre of the steps appeared a priest robed in white from head to foot, the veil parting over the crown; two new priests relieved those hitherto stationed at either corner, being naked half-way down to the breast, and covered, for the rest, in white and loose robes. At the same time, seated at the bottom of the steps, a priest commenced a solemn air upon a long wind-instrument of music. Half-way down the steps stood another flamen, holding in one hand the votive wreath, in the other a white wand; while, adding to the picturesque scene of that eastern ceremony, the stately ibis (bird sacred to the Egyptian worship) looked mutely down from the wall upon the rite, or stalked beside the altar at the base of the steps. At that altar now stood the sacrificial flamen. The countenance of Arbaces seemed to lose all its rigid calm while the aruspices inspected the entrails, and to be intent in pious anxiety--to rejoice and brighten as the signs were declared favorable, and the fire began bright and clearly to consume the sacred portion of the victim amidst odorous of myrrh and frankincense. It was then that a dead silence fell over the whispering crowd, and the priests gathering round the cella, another priest, naked save by a cincture round the middle, rushed forward, and dancing with wild gestures, implored an answer from the goddess. He ceased at last in exhaustion, and a low murmuring noise was heard within the body of the statue: thrice the head moved, and the lips parted, and then a hollow voice uttered these mystic words: There are waves like chargers that meet and glow, There are graves ready wrought in the rocks below, On the brow of the future the dangers lour, But blest are your barks in the fearful hour.
