Every one who has studied history is familiar with the myths which crowd its pages. I do not mean by this the frankly mythical tales which tell of gods and goddesses, of the divine founders of nations, tribes, and families, or those in which the Middle Ages delighted and which were replete with angels and devils, with witches and sorcerers, with magic and miracles. The myths to which I refer are those which masquerade as history, which are moden as well as ancient, which make no pretence to the supernatural, but which, being either pure invention or a huge growth from some little seed of fact, possess all the characteristics of their great namesakes which have rejoiced the world for centuries, awakened almost every emotion of which the human heart is capable, and from which the historian and the man of science have been able to learn innumerable lessons as to the toughs and beliefs, the hopes and fears, of primitive man. These historical myths grow up silently. Some of them reign for centuries. Modern research has exposed many of ancient lineage and long acceptance, has torn away the mask and revealed them in their true character. Yet the historical myth rarely dies. No exposure seems able to kill it. Expelled from every book of authority, from every dictionary and encyclopedia, it will still live on among the great mass of humanity. The reason for this tenacity of life is not far to seek. The myth, or the tradition, as it is sometimes called, has necessarily a touch of the imagination, and imagination is almost always more fascinating than truth. The historical myth, indeed, would not exist at all if it did not profess to tell something which people for one reason or another, like to believe, and which appeals strongly to some emotion or passion, and so to human nature.
