XXXV. a. Origin of Mythology

2. The Historical theory; according to which all the persons mentioned in mythology were once real human beings, and the legends and fabulous traditions relating to them are merely the additions and embellishments of later times. Thus the story of Æolus, the king and god of the winds, is supposed to have risen from the fact that Æolus was the ruler of some islands in the Tyrrhenian Sea, where he reigned as a just and pious king, and taught the natives the use of sails for ships, and how to tell from the signs of the atmosphere the changes of the weather and the winds. Cadmus, who, the legend says, sowed the earth with dragon’s teeth, from which sprang a crop of armed men, was in fact an emigrant from Phœnicia, and brought with him into Greece the knowledge of the letters of the alphabet, which he taught to the natives. From these rudiments of learning sprung civilization, which the poets have always been prone to describe as a deterioration of man’s first estate, the Golden Age of innocence and simplicity.
3. The Allegorical theory supposes that all the myths of the ancients were allegorical and symbolical, and contained some moral, religious, or philosophical truth or historical fact, under the form of an allegory, but came in process of time to be understood literally. Thus Saturn, who devours his own children, is the same power whom the Greeks called Cronos (Time), which may truly be said to destroy whatever it has brought into existence. The story of Io is interpreted in a similar manner. Io is the moon, and Argus the starry sky, which, as it were, keeps sleepless watch over her. The fabulous wanderings of Io represent the continual revolutions of the moon, which also suggested to Milton the same idea.
4. The Physical theory; according to which the elements of air, fire, and water were originally the objects of religious adoration, and the principal deities were personifications of the powers of nature. The transition was easy from a personification of the elements to the notion of supernatural beings presiding over and governing the different objects of nature. The Greeks, whose imagination was lively, peopled all nature with invisible beings, and supposed that every object, from the sun and sea to the smallest fountain and rivulet, was under the care of some particular divinity. Wordsworth, in his “Excursion,” has beautifully developed this view of Grecian mythology:
All the theories which have been mentioned are true to a certain extent. It would therefore be more correct to say that the mythology of a nation has sprung from all these sources combined than from any one in particular. We may add also that there are many myths which have arisen from the desire of man to account for those natural phenomena which he cannot understand; and not a few have had their rise from a similar desire of giving a reason for the names of places and persons.
