“In the first place,” said Brinnaria, “there should be the clearest understanding as to how much water I must carry.” “What do you mean?” the Emperor asked. “Well,” Brinnaria expounded, “a drop of water the size of my thumb-nail would not be enough, I presume. That would not be considered as demonstrating my innocence. You would expect me to carry more water than that. On the other hand, to exact that I carry a sieve full of water to the top of the rim, as if it were a pan, would be unfair to me.” “I see,” said Commodus. “I should lay down the condition that the water must cover the web of the sieve entirely and touch the rim all round, and that it should be a finger-breadth deep. Deeper than that it need not be, that depth would prove the favor of your Goddess as plainly as if you carried all Tiber. Is that all? If not, what next?” “Next,” she said, “it ought to be definitely agreed how far I must carry the sieve with the water in it.” “You do not need to carry it at all,” said Commodus. “If you stand up and hold the sieve of water as high as your chin, you will have proved the favor of your Goddess for you.” Lutorius, tactful and bland, here spoke up. “Your Majesty,” he said, “I doubt whether that will confute Brinnaria’s enemies or even convince the majority of the Pontiffs.” “What does it signify?” the Emperor demanded, “whether anybody else is convinced, if I am satisfied?” “Nothing whatever, your Majesty,” said Lutorius, “if you take that view of the matter.” “Perhaps,” Commodus admitted, “there may be something in your suggestion. Suppose we make the stipulation that she must carry the sieve of water from the brink of the river to the top of the steps.” “The number of steps,” Lutorius reminded him, “varies at different points along the Marble Quay.” “True,” the Emperor admitted. “Let us specify the middle stair, which has seven steps, if I mistake not. Do you agree to that?” he asked Brinnaria. “I agree,” she concluded. After Brinnaria had gone, Commodus resumed: “Now we must decide,” he said, “what kind of a sieve she is to use.” Causidiena spoke up, her all but sightless eyes strained towards the Emperor. “Lutorius and Numisia and I have talked over that question,” she said. “It seems to me that it would be unfair to her for us to decide on a metal sieve. They are always coarse and the apertures between the wires are comparatively large. It seems to us that no one could carry water in a copper sieve, not even by a miracle. “The meshes of linen sieves are the smallest of any made, but the linen does not seem to have much sustaining power. We feel that with a linen sieve not only Brinnaria would be, as Lutorius expressed it, severely handicapped for water-carrying, but that, as he also said, I fear irreverently, that Vesta herself would be too much handicapped in respect to miracle-working.”
