And this division is not arbitrary, but depends on the nature of the types and the aspect in which they present themselves to our view. Thus the sprig of acacia, although it is material, visible, and tangible, is, nevertheless, not to be treated as a material symbol; for, as it derives all its significance from its intimate connection with the legend of Hiram Abif, which is a mythical symbol, it cannot, without a violent and inexpedient disruption, be separated from the same class. For the same reason, the small hill near Mount Moriah, the search of the twelve Fellow Crafts, and the whole train of circumstances connected with the lost word, are to be viewed simply as mythical or legendary, and not as material symbols. These legends of Freemasonry constitute a considerable and a very important part of its ritual. Without them, the most valuable portions of the masonic as a scientific system would cease to exist. It is, in fact, in the traditions and legends of Freemasonry, more, even, than in its material symbols, that we are to find the deep religious instruction which the institution is intended to inculcate. It must be remembered that Freemasonry has been defined to be "a system of morality, veiled in allegory and illustrated by symbols." Symbols, then, alone, do not constitute the whole of the system: allegory comes in for its share; and this allegory, which veils the divine truths of masonry, is presented to the neophyte in the various legends which have been traditionally preserved in the order. The close connection, at least in design and method of execution, between the institution of Freemasonry and the ancient Mysteries, which were largely imbued with the mythical character of the ancient religions, led, undoubtedly, to the introduction of the same mythical character into the masonic system. So general, indeed, was the diffusion of the myth or legend among the philosophical, historical, and religious systems of antiquity, that Heyne remarks, on this subject, that all the history and philosophy of the ancients proceeded from myths.[141] The word _myth_, from the Greek μῦθος, _a story_, in its original acceptation, signified simply a statement or narrative of an event, without any necessary implication of truth or falsehood; but, as the word is now used, it conveys the idea of a personal narrative of remote date, which, although not necessarily untrue, is certified only by the internal evidence of the tradition itself.[142] Creuzer, in his "Symbolik," says that myths and symbols were derived, on the one hand, from the helpless condition and the poor and scanty beginnings of religious knowledge among the ancient peoples, and on the other, from the benevolent designs of the priests educated in the East, or of Eastern origin, to form them to a purer and higher knowledge.
