A symbol is properly a representation of any moral thing by the images or properties of natural things. Thus a circle is a symbol of eternity, as having neither beginning nor end; an eye is a symbol of wisdom; a lion, of courage; a lamb, of meekness and gentleness. This general idea of symbols is found in types, enigmas, parables, fables, allegories, emblems, hieroglyphics, &c. The symbols mostly used in the book of Revelation are _pictures_, and could be painted――and, indeed, a great part of the book could be represented in a _panorama_, and would constitute a series of the most splendid drawings that the world can conceive. The following remarks may throw some light on the reason why this mode of representation was adopted, and on the question whether a book written in this manner is necessarily unintelligible. (a) This method of representation is not uncommon in the ancient prophecies. A considerable portion of Daniel and Ezekiel is written in this way; and it is often resorted to by Isaiah and the other prophets. It was a method of representation which accorded well with the warm and glowing imagination of the Orientals, and with the character of mind in the early periods of the world. It was _supposed_ to be capable of conveying ideas of important events, although it was doubtless understood that there might be some degree of obscurity in the representation, and that study and ingenuity might be requisite in understanding it――as is always the case with parables and enigmas. We have frequent instances in the Bible of a certain kind of trial of skill in expounding dark sayings and riddles, when the sense was intentionally so conveyed as to demand acuteness of thought in the explanation. The {liii} utterance of truths in symbolic language accorded much with this prevailing bent of mind in the ancient and the oriental world――as we see in the symbolical representations in Egypt. If the use of symbols, therefore, in the Apocalypse be urged as an objection to the book, the objection would lie with equal force against no small part of the writings of the ancient Hebrew prophets, and against a method of writing which was actually in extensive use in the early ages of the world. To object to it, must be to object that our own methods and views were not the views and methods of all past ages; that the improved modes of communication in existence now were not in existence always.
