He who gathers the iris should be in a state of chastity. Three months beforehand let him soak the ground around the plant with hydromel—as a sort of atonement to appease the earth. When he comes to pluck it, he should first trace three circles about it with the point of a sword, and, the moment he plucks it, raise it aloft towards the heavens.[89] In another passage, in connection with the application of a mixture to an inflammatory tumor, Pliny says that persons of experience regard it as very important that the poultice be applied by a naked virgin and that both she and the patient be fasting. Touching the sufferer with the back of her hand, she is to say, “Apollo forbids a disease to increase which a naked virgin restrains.” Then, withdrawing her hand, she is to repeat the same words thrice and to join with the patient in spitting on the ground each time.[90] Pliny occasionally prefaces his marvelous remedies by some such expression as “it is said.” This circumstance is scarcely to be taken as a sign of mental reservation, however, as the following absurd statement, which he makes upon his own authority and declares is easily tested by experiment, will indicate. “If a person repents of a blow given to another, either by hand or with a missile, let him spit at once into the palm of the hand which inflicted the blow, and all resentment in the person struck will instantly vanish.” This is often proved, according to Pliny, in the case of beasts of burden, which can be induced to increase their speed by this method after the use of the whip has failed.[91] One can, perhaps, make some distinction between the strange influences which Pliny credited and the statements of the magi which he rejected. I believe that he did not go to the length of affirming that plants or parts of animals could cause panics, procure provisions, win you royal favor, gain for you vengeance on your enemies, or make you invisible. But he was inconsistent enough. After asserting that a single fish but a few inches long could immediately arrest the progress of the largest vessel by attaching itself to the keel of the ship,[92] was it for him to declare false the notion that a stone can calm winds or ward off hail and swarms of locusts? He characterized as “idle talk” the assertion of the magi that the stone “gorgonia” counteracted fascination,[93] but he had already written: “Id quoque convenit, quo nihil equidem libentius crediderim, tactis omnino menstruo postibus inritas fieri magorum artes, generis vanissimi, ut aestimare licet.”[94] Apparently, then, the only charge which he could bring against magicians without reflecting upon himself was that of malicious and criminal practices. His beliefs were much like theirs.
