But he himself agrees with this theory of mine; for he says shortly after, that not only philosophers, but even the ancient Romans, had separated superstition from religion; and that the word was first applied to those who prayed all day ut liberi sui sibi superstites essent, might survive them. On the etymology no one will depend who knows the remarkable absence of any etymological instinct in the ancients, in consequence of their weak grasp of that sound inductive method which has created modern criticism. But if it be correct, it is a natural and pathetic form for superstition to take in the minds of men who saw their children fade and die; probably the greater number of them beneath diseases which mankind could neither comprehend nor cure. The best exemplification of what the ancients meant by superstition is to be found in the lively and dramatic words of Aristotle's great pupil Theophrastus. The superstitious man, according to him, after having washed his hands with lustral water--that is, water in which a torch from the altar had been quenched--goes about with a laurel-leaf in his mouth, to keep off evil influences, as the pigs in Devonshire used, in my youth, to go about with a withe of mountain ash round their necks to keep off the evil eye. If a weasel crosses his path, he stops, and either throws three pebbles into the road, or, with the innate selfishness of fear, lets someone else go before him, and attract to himself the harm which may ensue. He has a similar dread of a screech-owl, whom he compliments in the name of its mistress, Pallas Athene. If he finds a serpent in his house, he sets up an altar to it. If he pass at a four-cross-way an anointed stone, he pours oil on it, kneels down, and adores it. If a rat has nibbled one of his sacks he takes it for a fearful portent--a superstition which Cicero also mentions. He dare not sit on a tomb, because it would be assisting at his own funeral. He purifies endlessly his house, saying that Hecate--that is, the moon--has exercised some malign influence on it; and many other purifications he observes, of which I shall only say that they are by their nature plainly, like the last, meant as preservatives against unseen malarias or contagions, possible or impossible. He assists every month with his children at the mysteries of the Orphic priests; and finally, whenever he sees an epileptic patient, he spits in his own bosom to avert the evil omen.
