It is a noteworthy circumstance that (setting apart Church miracles, and the epidemic of witchcraft which broke out simultaneously with the new learning of the Renaissance, and was fostered by the enlightened Protestantism of the Reformers, the Puritans, and the Covenanters, in England, Scotland and America) the minor miracles, the hauntings and knockings, are not more common in one age than in another. Our evidence, it is true, does not quite permit us to judge of their frequency at certain periods. The reason is obvious. We have no newspapers, no miscellanies of daily life, from Greece, Rome, and the Middle Ages. We have from Greece and Rome but few literary examples of 'Psychical Research,' few collections of books on 'Bogles' as Scott called them. We possess Palaephatus, the life of Apollonius of Tyana, jests in Lucian, argument and exposition from Pliny, Porphyry, Iamblichus, Plutarch, hints from Plato, Plautus, Lucretius, from St. Augustine and other fathers. Suetonius chronicles noises and hauntings after the death of Caligula, but, naturally, the historian does not record similar disturbances in the pauperum tabernaae. Classical evidence on these matters, as about Greek and Roman folklore in general, we have to sift painfully from the works of literary authors who were concerned with other topics. Still, in the region of the ghostly, as in folklore at large, we have relics enough to prove that the ancient practices and beliefs were on the ordinary level of today and of all days: and to show that the ordinary numbers of abnormal phenomena were supposed to be present in the ancient civilisations. In the Middle Ages--the 'dark ages'-- modern opinion would expect to find an inordinate quantity of ghostly material. But modern opinion would be disappointed. Setting aside saintly miracles, and accusations of witchcraft, the minor phenomena are very sparsely recorded. In the darkest of all 'dark ages,' when, on the current hypothesis, such tales as we examine ought to be most plentiful, even witch-trials are infrequent. Mr. Lecky attributes to these benighted centuries 'extreme superstition, with little terrorism, and, consequently, little sorcery'. The world was capable of believing anything, but it believed in the antidote as well as in the bane, in the efficacy of holy water as much as in the evil eye. When, with the dawn of enlightenment in the twelfth century, superstition became cruel, and burned witch and heretic, the charges against witches do not, as a rule, include the phenomena which we are studying. Witches are accused of raising storms, destroying crops, causing deaths and blighting marriages, by sympathetic magic; of assuming the shapes of beasts, of having intercourse with Satan, of attending the Sabbat. All these fables, except the last, are survivals from savage beliefs, but none of these occurrences are attested by modern witnesses of all sorts, like the 'knockings,' 'movements,' 'ghosts,'
