Closely akin to the power of numbers is that of words. Pliny once says of an incantation employed to avert hail-storms that he would not dare in seriousness to insert its words, although Cato in his work on agriculture prescribed a similar formula of meaningless words for the cure of fractured limbs.[430] But Pliny does not object to the repetition of incantations or prayers if the words spoken have some meaning. He informs us that _ocimum_ is sown with curses and maledictions and that when cummin seed is rammed down into the soil, the sowers pray it not to come up.[431] In another case the sower is to be naked and to pray for himself and his neighbors.[432] In a third case in which a poultice is to be applied to an inflammatory tumor, Pliny says that persons of experience regard it as very important that the poultice be put on 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.[433] Indeed, in another passage Pliny states that it is the universal custom in medicine to spit three times with incantations.[434] Perhaps the power of the words is thought to be increased or renewed by clearing the throat. Words were also occasionally spoken in plucking herbs. Ring-worm or tetter is treated by spitting upon and rubbing together two stones covered with a dry white moss, and by repeating a Greek incantation which may be translated, “Flee, Cantharides, a wild wolf seeks your blood.”[435] Abscesses and inflammations are treated with the herb _reseda_ and a Latin translation which seems irrelevant, if not quite senseless, and which may be translated, “Reseda, make disease recede. Don’t you know, don’t you know what chick has dug up these roots? May they have neither head nor feet.”[436] In the book following this passage Pliny raises the general question of the power of words to heal diseases.[437] He gives many instances of belief in incantations from contemporary popular superstition, from Roman religion, and from the annals of history. He does not doubt that Romans in the past have believed in the power of words, and thinks that if we accept set forms of prayer and religious formulae, we must also admit the force of incantations. But he adds that the wisest individuals believe in neither. [Sidenote: Attitude to love-charms and birth-control.]
