THE LYSE FIORD.
The fear of the tempest belongs to every age. The ancient Greeks, from whom the Romans borrowed and modified the myth, told how Hephaistos toiled in his volcanic forge to form the bolts of Zeus, great father of gods and men. These flaming weapons could none oppose. By them rebellious giants were overturned. And the bold Goth, rugged and vigorous, heard the voice of the war-god, Thor, shout to him:
“Mine eyes are the lightning,
The wheels of my chariot
Roll in the thunder!”
The Arab saw the wild combat of genii, whom the great Solomon had not subdued. Woe to the luckless wight who should arouse their ill-will! The Arabian Nights tell us of a contest between one of these spirits of fire and a beautiful princess, versed in magic. The swarthy Moor beheld the hand of God, waving on his angels to contest with the hosts of evil: and the same idea of wild combat in the spirit world is found in the myths of the Caribs and Lapps. In the Hindoo cosmogony, the lightning and storm are the chief weapons of Siva, the destroyer, who will one day blot the world out of existence. Only in the red man’s tales do we find the idea of the Christian world, of one Great Spirit who rules all nature. In the Persian mythology, lightning and gloom represent the contest between the forces of Ahriman, prince of evil, and Ormuzd, the great creator and preserver of good. And among the old Etruscans, from whom the Romans borrowed many rites and ceremonies, the lightning was one of the chief objects in their system of augury and divination. A favorable flash of lightning outweighed all portents of ill. The thunder was the voice of the gods, communicating their will to men.
And so the ancients were content to pass the mystery by, unsolved. Now and then a Pliny, a Seneca, an Aristotle, ventured a timid speculation upon the origin and cause of lightning, but as electricity was an unknown force to them, their conjectures were as wild as the chimærical tales of Cimmerian darkness in ultra-Scythian realms, or of the Utopian haven of bliss, where the Hyperboreans dwelt. But one of their various conjectures is worthy of note, as it contains an element of truth. It was, that the lightning was produced by mutual friction or violent concussion of the clouds.
Since electricity has been recognized as the agent in the phenomena of thunder storms, inquiry as to whether it is a cause or a result of the formation of clouds, has produced evidence in favor of the latter fact (though clouds differently charged have mutual attraction for each other), for rapid motion of gases may be made to generate electricity. A natural sequence would be that thunder storms are most violent where clouds are heaviest. Hence, thunder storms are naturally most frequent and violent in the tropics, where the greater heat produces immense masses of vapor. and are unknown in the polar world, where the comparative dryness of the atmosphere is unfavorable. The unusual amount of electricity in dense clouds in rapid motion is shown by the tremendous electrical displays attendant upon tornadoes and cyclones. Another illustration of lightning resulting from cloud agency, rather than controlling them, may be found in the cloudless Sahara, where evidences of electricity are sometimes to be observed in the time of the Khamsin, while the thunder storm is unknown. One notable exception to the rule that thunder storms are violent and frequent in all tropical regions is to be found in Peru, with its cloudless skies and eternal sun, where a rainfall or a thunder storm would be as great a curiosity as a palm tree at the north pole. The mere fact of elevation renders the thunder storm more violent in mountainous regions, in both temperate and tropical worlds.
Knowing the character of this mysterious power, we may not enter upon a lengthy discussion of the changes, chemical, physical and otherwise, that may be produced by it. Within the scope of this work, only its rank as an agent of destruction and a historical factor may be considered. Is electricity to be greatly feared? to be put on a par with the flood, the hurricane, and the earthquake? Has it ever figured in the history of nations sufficiently to directly affect their destinies?
The first and most familiar aspect of its power is the thunder storm, which needs not a word of description. It results merely from the discharges passing between two bodies oppositely charged. There is one comparatively rare form of lightning, in which it appears as a globe of fire slowly descending, with wayward and unexpected dashes to the side, sometimes coming down a chimney and playing about the floor like a kitten, much to the discomfiture of the inmates, till it at length explodes with immense force, hurling zig-zag lightnings all about. This peculiar freak, several times observed, is as yet unexplained.
