“A mighty sensible remark,” Commodus cut in, “and one with which I concur. You are more of a sport than I thought you, Lutorius.” “Considering only the construction of sieves,” Causidiena continued, “we were of the opinion that a horsehair sieve would be the fairest. The hairs are coarser than linen threads and finer than copper wires and the apertures between are similarly of medium size, as sieves go. “Besides, we have ascertained that horse-hair sieves are by far the most usual kind. We are told that in most sieve-shops in Rome all the linen sieves and copper sieves sold do not amount to one-third the horsehair sieves.” “That ought to settle that point,” said Commodus. “No one can cavil if we use the commonest kind of sieve, of medium fineness and of normal make. “As to the question of procuring one we must arrange that Brinnaria may feel wholly secure that it has not been tampered with by some enemy of hers, and, on the other hand, that all persons whatever, to whomsoever hostile or friendly, or wholly indifferent, may be at once and forever certain that neither Brinnaria nor any partisan of hers has had any access to it before the test. Have you any suggestions to make?” “Yes,” Causidiena replied. “Lutorius and Numisia and I have debated that point and have come to a conclusion which we think you might approve. The best sieve-maker in Rome is Caius Truttidius Falcifer, a tenant of one of our shops on the Holy Street. Not only are his wares reputed the best-made sieves produced in Rome, but he sells more than anyone else and carries a larger stock than can be found in the possession of any other dealer. He is sieve-maker to the Atrium, like his father before him. His horse-hair sieves are the closest and finest of their kind. We use them to sift the flour for our ceremonial cakes. I had some brought to show you. Where are they, Numisia?” Numisia rose and took from an onyx console a flattish dish-like basket of gilt wicker, containing a number of square cakes. In size and on account of the ridges on them, each looked much like the joined four fingers of a man’s hand. Commodus took one, broke it and munched a piece. “Very good,” he said. “If the excellence of the pastry demonstrates the virtue of the sieve let us consider it proved. I do not see, however, what the cakes have to do with it. But I am entirely willing to agree that Brinnaria is to use a horse-hair sieve made by Truttidius. “Now, how are we to select the particular sieve so as to convince all concerned that it is a normal sieve chosen at random and not one doctored for the occasion?” “Our idea,” said Lutorius, “was to arrange that Truttidius be present with a number of horse-hair sieves, practically with his whole stock of his best, and that one of those be chosen before the whole College of Pontiffs, perhaps by your Majesty, perhaps by some one of the altar-boys, blindfolded, if you like that idea, or in any other manner which seems good to you.”
