This belief, in its essential characteristics, was the same in the remote periods of antiquity as in more recent times; and a similar analogy exists between the modifications of it which are now entertained in different and widely separated countries.
The variations which it is found to possess are dependent upon those peculiarities of habit, religion, and social life which characterize each nation. This fact gives an important clue by which we may unravel the actual nature of the phenomena which are embodied in the belief. But previously to entering upon this task it is requisite to point out a remote consequence of mythological and legendary lore which exercises a highly important influence on the minds of most if not all persons at the present time.
The numerous myths which were retained, the implicit faith reposed in them, and the great extent to which the practice of the occult sciences was carried in the Middle Ages, fostered ideas respecting the influence which supernatural beings exercised in the ordinary affairs of life, which rivalled in extent and variety those entertained before the Christian era; but they received perhaps a more gloomy character from the doctrine of the agency of devils.
The prevalence of these superstitions throws a wild and weird-like shadow over the history of those periods, and one of the chief results was that the records of local and general events became pregnant with mysterious occurrences and supernatural interpositions; and a mass of legends, teeming with remnants of ancient myths, more or less modified, giants, demons, witches, wizards, ghosts, portents, &c., have been perpetuated to modern times, and have formed an inexhaustible mine to the novelist and romance-writer.
There are few localities in England which do not possess legends or tradition of this nature; and the standard nursery and children's tales are full of supernatural personages and occurrences in which are set aside all the known laws of matter and force, and time and space are alike annihilated. Many of these tales are of great interest, for in them we find degenerated forms of some of the most ancient traditions and myths of our own and other races.
The adventures of Jack the Giant-Killer, the most celebrated of all celebrated nursery heroes, are for the most part derived from the fabulous era of our own country, and from Scandinavian mythology; and the whole tale is a degraded and vitiated tradition in which the deeds of Corineus, a celebrated personage in the mythical history of Britain, and Prince Arthur; the adventures of Thor, the god of thunder, and other Scandinavian deities, are jumbled together in strange confusion.
Geoffrey of Monmouth, in his British History[39] states that the early inhabitants of this island were giants. Brutus, a grandson of Ascanius, the companion of Æneas in his flight from Troy, and Corineus, also of Trojan descent, guided by a dream, discovered Britain, and delighted with "the pleasant situation of the place, the plenty of rivers abounding with fish, and the engaging prospect of its woods," they became desirous of fixing their habitation in so desirable a country, and landing, drove the giants into the fastnesses of the mountains, and divided the country.
To Corineus was apportioned that part of the island which we call Cornwall, and it is recorded that he had selected this portion of the island for his share, because "it was a diversion to him to encounter the said giants, which were in greater numbers there than in all the other provinces that fell to the share of his companions."
Corineus is described as being "an ardent man in matters of council, and of great courage and boldness; who in an encounter with any person, even of gigantic stature, would immediately overthrow him as if he were a child."
In the same fabulous history (B. X, ch. 3) it is stated, that a giant who had invaded our shores, and taken refuge at the top of St. Michael's Mount, was attacked by King Arthur in the night and killed; the country being thus freed "from a most destructive and voracious monster."
