Webster defines _symbol_ as follows: "The sign or representation of any moral thing by the images or properties of natural things. Thus, a lion is the _symbol_ of courage; the lamb is the _symbol_ of meekness or patience." Home, in his Introduction to the Study of the Bible, says: "By symbols we mean certain representative marks, rather than express pictures; or, if pictures, such as were at the time _characters_, and besides presenting to the eye the resemblance of a particular object, suggested a general idea to the mind, as when a _horn_ was made to denote _strength_, an _eye_ and _scepter, majesty_, and in numberless such instances; where the picture was not drawn to express merely the thing itself, but something else, which was, or was conceived to be, analagous to it." The main idea, then, as expressed in the foregoing definitions, is the representation of an object, not by a picture of itself, but by something analagous, such as the exhibition of moral qualities by images drawn from nature. But the use of symbols is not confined to the representation of moral subjects alone. Anything may be symbolized to which a corresponding analagous object can be found. To establish the principle of analogy here laid down, it will be necessary to refer only to a few of the numerous examples of divinely interpreted symbols in the Scriptures. Any one can readily perceive the analogy between the seven fat kine of Pharaoh's dream and as many years of plenty; so, also, with the seven full, healthy ears that grew up on seven stalks. Likewise, the analogy between the seven thin kine and as many years of famine, and the seven thin, blasted ears that represented the same thing, is apparent. One fat kine or one full ear would symbolize one year of plenty, when crops were abundant; while seven would represent as many distinct seasons of prosperity, etc. Kine do not represent kine, but something analagous. The beasts of Daniel's visions do not represent animals like themselves, or a multitude of such animals, but something of analagous disposition. The analogy between a wild, ferocious beast, stamping upon or devouring everything within its reach, and a cruel, persecuting, tyrannical government is apparent. A horn does not signify a horn, but some great power, such as a dynasty of kings or rulers; and what the horn is to the animal in manifesting its desolating disposition, kings and rulers are to an empire in executing the persecuting or oppressive principles of the body politic. A pure, chaste virgin is used to symbolize the true church of God; whereas a corrupt harlot is chosen to represent an apostate church, and fornication her idolatrous worship.
